---------------------------------
-
-2.1. Grants
-
-Each Contributor hereby grants You a world-wide, royalty-free,
-non-exclusive license:
-
-(a) under intellectual property rights (other than patent or trademark)
-    Licensable by such Contributor to use, reproduce, make available,
-    modify, display, perform, distribute, and otherwise exploit its
-    Contributions, either on an unmodified basis, with Modifications, or
-    as part of a Larger Work; and
-
-(b) under Patent Claims of such Contributor to make, use, sell, offer
-    for sale, have made, import, and otherwise transfer either its
-    Contributions or its Contributor Version.
-
-2.2. Effective Date
-
-The licenses granted in Section 2.1 with respect to any Contribution
-become effective for each Contribution on the date the Contributor first
-distributes such Contribution.
-
-2.3. Limitations on Grant Scope
-
-The licenses granted in this Section 2 are the only rights granted under
-this License. No additional rights or licenses will be implied from the
-distribution or licensing of Covered Software under this License.
-Notwithstanding Section 2.1(b) above, no patent license is granted by a
-Contributor:
-
-(a) for any code that a Contributor has removed from Covered Software;
-    or
-
-(b) for infringements caused by: (i) Your and any other third party's
-    modifications of Covered Software, or (ii) the combination of its
-    Contributions with other software (except as part of its Contributor
-    Version); or
-
-(c) under Patent Claims infringed by Covered Software in the absence of
-    its Contributions.
-
-This License does not grant any rights in the trademarks, service marks,
-or logos of any Contributor (except as may be necessary to comply with
-the notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-No Contributor makes additional grants as a result of Your choice to
-distribute the Covered Software under a subsequent version of this
-License (see Section 10.2) or under the terms of a Secondary License (if
-permitted under the terms of Section 3.3).
-
-2.5. Representation
-
-Each Contributor represents that the Contributor believes its
-Contributions are its original creation(s) or it has sufficient rights
-to grant the rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-This License is not intended to limit any rights You have under
-applicable copyright doctrines of fair use, fair dealing, or other
-equivalents.
-
-2.7. Conditions
-
-Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
-in Section 2.1.
-
-3. Responsibilities
--------------------
-
-3.1. Distribution of Source Form
-
-All distribution of Covered Software in Source Code Form, including any
-Modifications that You create or to which You contribute, must be under
-the terms of this License. You must inform recipients that the Source
-Code Form of the Covered Software is governed by the terms of this
-License, and how they can obtain a copy of this License. You may not
-attempt to alter or restrict the recipients' rights in the Source Code
-Form.
-
-3.2. Distribution of Executable Form
-
-If You distribute Covered Software in Executable Form then:
-
-(a) such Covered Software must also be made available in Source Code
-    Form, as described in Section 3.1, and You must inform recipients of
-    the Executable Form how they can obtain a copy of such Source Code
-    Form by reasonable means in a timely manner, at a charge no more
-    than the cost of distribution to the recipient; and
-
-(b) You may distribute such Executable Form under the terms of this
-    License, or sublicense it under different terms, provided that the
-    license for the Executable Form does not attempt to limit or alter
-    the recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-You may create and distribute a Larger Work under terms of Your choice,
-provided that You also comply with the requirements of this License for
-the Covered Software. If the Larger Work is a combination of Covered
-Software with a work governed by one or more Secondary Licenses, and the
-Covered Software is not Incompatible With Secondary Licenses, this
-License permits You to additionally distribute such Covered Software
-under the terms of such Secondary License(s), so that the recipient of
-the Larger Work may, at their option, further distribute the Covered
-Software under the terms of either this License or such Secondary
-License(s).
-
-3.4. Notices
-
-You may not remove or alter the substance of any license notices
-(including copyright notices, patent notices, disclaimers of warranty,
-or limitations of liability) contained within the Source Code Form of
-the Covered Software, except that You may alter any license notices to
-the extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-You may choose to offer, and to charge a fee for, warranty, support,
-indemnity or liability obligations to one or more recipients of Covered
-Software. However, You may do so only on Your own behalf, and not on
-behalf of any Contributor. You must make it absolutely clear that any
-such warranty, support, indemnity, or liability obligation is offered by
-You alone, and You hereby agree to indemnify every Contributor for any
-liability incurred by such Contributor as a result of warranty, support,
-indemnity or liability terms You offer. You may include additional
-disclaimers of warranty and limitations of liability specific to any
-jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
----------------------------------------------------
-
-If it is impossible for You to comply with any of the terms of this
-License with respect to some or all of the Covered Software due to
-statute, judicial order, or regulation then You must: (a) comply with
-the terms of this License to the maximum extent possible; and (b)
-describe the limitations and the code they affect. Such description must
-be placed in a text file included with all distributions of the Covered
-Software under this License. Except to the extent prohibited by statute
-or regulation, such description must be sufficiently detailed for a
-recipient of ordinary skill to be able to understand it.
-
-5. Termination
---------------
-
-5.1. The rights granted under this License will terminate automatically
-if You fail to comply with any of its terms. However, if You become
-compliant, then the rights granted under this License from a particular
-Contributor are reinstated (a) provisionally, unless and until such
-Contributor explicitly and finally terminates Your grants, and (b) on an
-ongoing basis, if such Contributor fails to notify You of the
-non-compliance by some reasonable means prior to 60 days after You have
-come back into compliance. Moreover, Your grants from a particular
-Contributor are reinstated on an ongoing basis if such Contributor
-notifies You of the non-compliance by some reasonable means, this is the
-first time You have received notice of non-compliance with this License
-from such Contributor, and You become compliant prior to 30 days after
-Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-infringement claim (excluding declaratory judgment actions,
-counter-claims, and cross-claims) alleging that a Contributor Version
-directly or indirectly infringes any patent, then the rights granted to
-You by any and all Contributors for the Covered Software under Section
-2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all
-end user license agreements (excluding distributors and resellers) which
-have been validly granted by You or Your distributors under this License
-prior to termination shall survive termination.

+Project Mentat is a persistent, embedded knowledge base. It draws heavily on [DataScript](https://github.com/tonsky/datascript) and [Datomic](http://datomic.com).

[Their repository](https://github.com/mozilla/mentat) was marked read-only, [this fork](https://github.com/qpdb/mentat) is an attempt to revive and continue that interesting work.  We owe the team at Mozilla more than words can express for inspiring us all and for this project in particular.
 
+*Thank you*.
+
+[Documentation](https://docs.rs/mentat)
+
+---
 
 ## Motivation
 
-Datomish is intended to be a flexible relational (not key-value, not document-oriented) store that doesn't leak its storage schema to users, and doesn't make it hard to grow its domain schema and run arbitrary queries.
+Mentat is a flexible relational (not key-value, not document-oriented) store that makes it easy to describe, grow, and reuse your domain schema.
 
-Our short-term goal is to build a system that, as the basis for a User Agent Service, can support multiple [Tofino](https://github.com/mozilla/tofino) UX experiments without having a storage engineer do significant data migration, schema work, or revving of special-purpose endpoints.
+By abstracting away the storage schema, and by exposing change listeners outside the database (not via triggers), we hope to make domain schemas stable, and allow both the data store itself and embedding applications to use better architectures, meeting performance goals in a way that allows future evolution.
+
+## Data storage is hard
+
+We've observed that data storage is a particular area of difficulty for software development teams:
+
+- It's hard to define storage schemas well. A developer must:
+  - Model their domain entities and relationships.
+  - Encode that model _efficiently_ and _correctly_ using the features available in the database.
+  - Plan for future extensions and performance tuning.
+
+  In a SQL database, the same schema definition defines everything from high-level domain relationships through to numeric field sizes in the same smear of keywords. It's difficult for someone unfamiliar with the domain to determine from such a schema what's a domain fact and what's an implementation concession — are all part numbers always 16 characters long, or are we trying to save space? — or, indeed, whether a missing constraint is deliberate or a bug.
+
+  The developer must think about foreign key constraints, compound uniqueness, and nullability. They must consider indexing, synchronizing, and stable identifiers. Most developers simply don't do enough work in SQL to get all of these things right. Storage thus becomes the specialty of a few individuals.
+
+   Which one of these is correct?
+
+   ```edn
+   {:db/id          :person/email
+    :db/valueType   :db.type/string
+    :db/cardinality :db.cardinality/many     ; People can have multiple email addresses.
+    :db/unique      :db.unique/identity      ; For our purposes, each email identifies one person.
+    :db/index       true}                    ; We want fast lookups by email.
+   {:db/id          :person/friend
+    :db/valueType   :db.type/ref
+    :db/cardinality :db.cardinality/many}    ; People can have many friends.
+   ```
+   ```sql
+   CREATE TABLE people (
+     id INTEGER PRIMARY KEY,  -- Bug: because of the primary key, each person can have no more than 1 email.
+     email VARCHAR(64),       -- Bug?: no NOT NULL, so a person can have no email.
+                              -- Bug: nobody will ever have a long email address, right?
+   );
+   CREATE TABLE friendships (
+     FOREIGN KEY person REFERENCES people(id),  -- Bug?: no indexing, so lookups by friend or person will be slow.
+     FOREIGN KEY friend REFERENCES people(id),  -- Bug: no compound uniqueness constraint, so we can have dupe friendships.
+   );
+   ```
+
+   They both have limitations — the Mentat schema allows only for an open world (it's possible to declare friendships with people whose email isn't known), and requires validation code to enforce email string correctness — but we think that even such a tiny SQL example is harder to understand and obscures important domain decisions.
+
+- Queries are intimately tied to structural storage choices. That not only hides the declarative domain-level meaning of the query — it's hard to tell what a query is trying to do when it's a 100-line mess of subqueries and `LEFT OUTER JOIN`s — but it also means a simple structural schema change requires auditing _every query_ for correctness.
+
+- Developers often capture less event-shaped than they perhaps should, simply because their initial requirements don't warrant it. It's quite common to later want to [know when a fact was recorded](https://bugzilla.mozilla.org/show_bug.cgi?id=1341939), or _in which order_ two facts were recorded (particularly for migrations), or on which device an event took place… or even that a fact was _ever_ recorded and then deleted.
+
+- Common queries are hard. Storing values only once, upserts, complicated joins, and group-wise maxima are all difficult for non-expert developers to get right.
+
+- It's hard to evolve storage schemas. Writing a robust SQL schema migration is hard, particularly if a bad migration has ever escaped into the wild! Teams learn to fear and avoid schema changes, and eventually they ship a table called `metadata`, with three `TEXT` columns, so they never have to write a migration again. That decision pushes storage complexity into application code. (Or they start storing unversioned JSON blobs in the database…)
+
+- It's hard to share storage with another component, let alone share _data_ with another component. Conway's Law applies: your software system will often grow to have one database per team.
+
+- It's hard to build efficient storage and querying architectures. Materialized views require knowledge of triggers, or the implementation of bottleneck APIs. _Ad hoc_ caches are often wrong, are almost never formally designed (do you want a write-back, write-through, or write-around cache? Do you know the difference?), and often aren't reusable. The average developer, faced with a SQL database, has little choice but to build a simple table that tries to meet every need.
 
 
 ## Comparison to DataScript
 
-DataScript asks the question: "What if creating a database would be as cheap as creating a Hashmap?"
+DataScript asks the question: "What if creating a database were as cheap as creating a Hashmap?"
 
-Datomish is not interested in that. Instead, it's strongly interested in persistence and performance, with very little interest in immutable databases/databases as values or throwaway use.

+One might say that Mentat's question is: "What if a database could store arbitrary relations, for arbitrary consumers, without them having to coordinate an up-front storage-level schema?"
+
+Consider this a practical approach to facts, to knowledge its storage and access, much like SQLite is a practical RDBMS.
 
 (Note that [domain-level schemas are very valuable](http://martinfowler.com/articles/schemaless/).)
 
-Another possible question would be: "What if we could bake some of the concepts of CQRS and event sourcing into a persistent relational store, such that the transaction log itself were of value to queries?"

 Some thought has been given to how databases as values — long-term references to a snapshot of the store at an instant in time — could work in this model. It's not impossible; it simply has different performance characteristics.
 
-Just like DataScript, Datomish speaks Datalog for querying and takes additions and retractions as input to a transaction. Unlike DataScript, Datomish's API is asynchronous.

 Many of these design decisions are inapplicable to deployed desktop software; indeed, the use of multiple JVM processes makes Datomic's use in a small desktop app, or a mobile device, prohibitive.
 
-Datomish is designed for embedding, initially in an Electron app ([Tofino](https://github.com/mozilla/tofino)). It is less concerned with exposing consistent database states outside transaction boundaries, because that's less important here, and dropping some of these requirements allows us to leverage SQLite itself.

 ## Comparison to SQLite
 
-SQLite is a traditional SQL database in most respects: schemas conflate semantic, structural, and datatype concerns; the main interface with the database is human-first textual queries; sparse and graph-structured data are 'unnatural', if not always inefficient; experimenting with and evolving data models are error-prone and complicated activities; and so on.

-Datomish aims to offer many of the advantages of SQLite — single-file use, embeddability, and good performance — while building a more relaxed and expressive data model on top.

+## Building
 
-At present this code is licensed under MPLv2.0. That license is subject to change prior to external contributions.
+You first need to clone the project.  To build and test the project, we are using [Cargo](https://crates.io/install).
+
+To build all of the crates in the project use:
+
+````
+cargo build
+````
+
+To run tests use:
+
+````
+# Run tests for everything.
+cargo test --all
+
+# Run tests for just the query-algebrizer folder (specify the crate, not the folder),
+# printing debug output.
+cargo test -p mentat_query_algebrizer -- --nocapture
+````
+
+For most `cargo` commands you can pass the `-p` argument to run the command just on that package. So, `cargo build -p mentat_query_algebrizer` will build just the "query-algebrizer" folder.
+
+## What are all of these crates?
+
+We use multiple sub-crates for Mentat for four reasons:
+
+1. To improve incremental build times.
+2. To encourage encapsulation; writing `extern crate` feels worse than just `use mod`.
+3. To simplify the creation of targets that don't use certain features: _e.g._, a build with no syncing, or with no query system.
+4. To allow for reuse (_e.g._, the EDN parser is essentially a separate library).
+
+So what are they?
+
+### Building blocks
+
+#### `edn`
+
+Our EDN parser. It uses `rust-peg` to parse [EDN](https://github.com/edn-format/edn), which is Clojure/Datomic's richer alternative to JSON. `edn`'s dependencies are all either for representing rich values (`chrono`, `uuid`, `ordered-float`) or for parsing (`serde`, `peg`).
+
+In addition, this crate turns a stream of EDN values into a representation suitable to be transacted.
+
+#### `mentat_core`
+
+This is the lowest-level Mentat crate. It collects together the following things:
+
+- Fundamental domain-specific data structures like `ValueType` and `TypedValue`.
+- Fundamental SQL-related linkages like `SQLValueType`. These encode the mapping between Mentat's types and values and their representation in our SQLite format.
+- Conversion to and from EDN types (_e.g._, `edn::Keyword` to `TypedValue::Keyword`).
+- Common utilities (some in the `util` module, and others that should be moved there or broken out) like `Either`, `InternSet`, and `RcCounter`.
+- Reusable lazy namespaced keywords (_e.g._, `DB_TYPE_DOUBLE`) that are used by `mentat_db` and EDN serialization of core structs.
+
+### Types
+
+#### `mentat_query`
+
+This crate defines the structs and enums that are the output of the query parser and used by the translator and algebrizer. `SrcVar`, `NonIntegerConstant`, `FnArg`… these all live here.
+
+#### `mentat_query_sql`
+
+Similarly, this crate defines an abstract representation of a SQL query as understood by Mentat. This bridges between Mentat's types (_e.g._, `TypedValue`) and SQL concepts (`ColumnOrExpression`, `GroupBy`). It's produced by the algebrizer and consumed by the translator.
+
+### Query processing
+
+#### `mentat_query_algebrizer`
+
+This is the biggest piece of the query engine. It takes a parsed query, which at this point is _independent of a database_, and combines it with the current state of the schema and data. This involves translating keywords into attributes, abstract values into concrete values with a known type, and producing an `AlgebraicQuery`, which is a representation of how a query's Datalog semantics can be satisfied as SQL table joins and constraints over Mentat's SQL schema. An algebrized query is tightly coupled with both the disk schema and the vocabulary present in the store when the work is done.
+
+#### `mentat_query_projector`
+
+A Datalog query _projects_ some of the variables in the query into data structures in the output. This crate takes an algebrized query and a projection list and figures out how to get values out of the running SQL query and into the right format for the consumer.
+
+#### `mentat_query_translator`
+
+This crate works with all of the above to turn the output of the algebrizer and projector into the data structures defined in `mentat_query_sql`.
+
+#### `mentat_sql`
+
+This simple crate turns those data structures into SQL text and bindings that can later be executed by `rusqlite`.
+
+### The data layer: `mentat_db`
+
+This is a big one: it implements the core storage logic on top of SQLite. This crate is responsible for bootstrapping new databases, transacting new data, maintaining the attribute cache, and building and updating in-memory representations of the storage schema.
+
+### The main crate
+
+The top-level main crate of Mentat assembles these component crates into something useful. It wraps up a connection to a database file and the associated metadata into a `Store`, and encapsulates an in-progress transaction (`InProgress`). It provides modules for programmatically writing (`entity_builder.rs`) and managing vocabulary (`vocabulary.rs`).
+
+### Syncing
+
+Sync code lives, for [referential reasons](https://engineering.linkedin.com/distributed-systems/log-what-every-software-engineer-should-know-about-real-time-datas-unifying), in a crate named `tolstoy`. This code is a work in progress; current state is a proof-of-concept implementation which largely relies on the internal transactor to make progress in most cases and comes with a basic support for timelines. See [Tolstoy's documentation](https://github.com/mozilla/mentat/tree/master/tolstoy/README.md) for details.
+
+### The command-line interface
+
+This is under `tools/cli`. It's essentially an external consumer of the main `mentat` crate. This code is ugly, but it mostly works.

 ## SQLite dependencies
 
-Datomish uses partial indices, which are available in SQLite 3.8.0 and higher.
+Mentat uses partial indices, which are available in SQLite 3.8.0 and higher. It relies on correlation between aggregate and non-aggregate columns in the output, which was added in SQLite 3.7.11.
 
 It also uses FTS4, which is [a compile time option](http://www.sqlite.org/fts3.html#section_2).
 
-## Running a REPL
+By default, Mentat specifies the `"bundled"` feature for `rusqlite`, which uses a relatively recent
+version of SQLite. If you want to link against the system version of SQLite, omit `"bundled_sqlite3"`
+from Mentat's features.
 
-### Prep
-
-You'll need [Leiningen](http://leiningen.org).
-
-```
-# If you use nvm.
-nvm use 6
-
-lein deps
-npm install
-
-# If you want a decent REPL.
-brew install rlwrap
+```toml
+[dependencies.mentat]
+version = "0.6"
+# System sqlite is known to be new.
+default-features = false
 ```
 
-Run `lein cljsbuild auto advanced` to generate JavaScript into `target/`.

-### Starting a ClojureScript REPL from the terminal
+## License
 
-```
-rlwrap lein run -m clojure.main repl.clj
-```
-
-### Connecting to a ClojureScript environment from Vim
-
-You'll need `vim-fireplace`. Install using Pathogen.
-
-First, start a Clojure REPL with an nREPL server. Then load our ClojureScript REPL and dependencies. Finally, connect to it from Vim.
-
-```
-$ lein repl

-
-Now you can use `:Eval`, `cqc`, and friends to evaluate code. Fireplace should connect automatically, but if it doesn't:
-
-```
-:Connect nrepl://localhost:62385
-```
-
-## To run the ClojureScript tests
-
-Run `lein doo node test once`, or `lein doo node` to re-run on file changes.
-
-### Preparing an NPM release
-
-The intention is that the `release-js/` directory is roughly the shape of an npm-ready JavaScript package.
-
-To generate a require/import-ready `release-js/datomish.js`, run
-```
-lein cljsbuild once release
-```
-To verify that importing into Node.js succeeds, run
-```
-node release-js/test
-```
-
-Many thanks to ([David Nolen](https://github.com/swannodette)) and ([Nikita Prokopov](https://github.com/tonsky)) for demonstrating how to package ClojureScript for distribution via npm.

 # Style Guide
 
+Our Rust code approximately follows the [Rust style guide](https://github.com/rust-lang-nursery/fmt-rfcs/blob/master/guide/guide.md). We use four-space indents, with categorized and alphabetized imports; see the examples in the tree. We try to follow [these guidelines](https://aturon.github.io/), too.
+
+We do not automatically use `rustfmt` because it tends to make code incrementally worse, but you should be prepared to consider its suggestions.
+
+An example of 'good' Rust code, omitting the license block:
+
+```rust
+#![allow(…)]
+
+extern crate foo;

+use std::borrow::Borrow;
+use std::error::Error;
+use std::iter::{once, repeat};

+
+pub type Thing = Borrow<String>;
+
+pub fn foo_thing(x: Thing) -> Result<(), MyError> {
+    // Do things here.
+}
+```
+
 Our JavaScript code follows the [airbnb style](https://github.com/airbnb/javascript)
 with a [few exceptions](../../blob/master/.eslintrc). The precise rules are
 likely to change a little as we get started so for now let eslint be your guide.

+# Worked examples of modeling data using Mentat
+
+Used correctly, Mentat makes it easy for you to grow to accommodate new kinds of data, for data to synchronize between devices, for multiple consumers to share data, and even for errors to be fixed.
+
+But what does "correctly" mean?
+
+The following discussion and set of worked examples aim to help. During discussion sections a simplified syntax is used for schema examples.
+
+## Principles
+
+### Think about the domain, not about your UI
+
+Given a set of mockups, or an MVP list of requirements, it's easy to leap into defining a data model that supports exactly those things. In doing so we will likely end up with a data model that can't support future capabilities, or that has crucial mismatches with the real world.
+
+For example, one might design a contact manager UI like macOS's — a list of string fields for a person:
+
+* First name
+* Last name
+* Address line 1
+* Address line 2
+* Phone
+* _etc._
+
+We might model this in Mentat as simple value properties:
+
+```edn
+[:person/name                  :db.type/string :db.cardinality/one]      ; Incorrect: people can have many names!
+[:person/home_address_line_one :db.type/string :db.cardinality/one]
+[:person/home_address_line_two :db.type/string :db.cardinality/one]
+[:person/home_city             :db.type/string :db.cardinality/one]
+[:person/home_phone            :db.type/string :db.cardinality/one]
+```
+
+or in JSON as a simple object:
+
+```json
+{
+ "name": "Alice Smith",
+ "home_address_line_one": "123 Main St",
+ "home_city": "Anywhere",
+ "home_phone": "555-867-5309"
+}
+```
+
+We might realize that this proliferation of attributes is going in the wrong direction, and add nested structure:
+
+```json
+{
+ "name": "Alice Smith",
+ "home_address": {
+   "line_one": "123 Main St",
+   "city": "Anywhere"
+ }}
+```
+
+(quick, is a home phone number a property of the address or the person?)
+
+Or we might allow for some people having multiple addresses and multiple homes:
+
+```json
+{"name": "Alice Smith",
+ "addresses": [{
+   "type": "home",
+   "line_one": "123 Main St",
+   "city": "Anywhere"
+ }]}
+```
+
+There are [lots of reasons the address model is wrong](https://www.mjt.me.uk/posts/falsehoods-programmers-believe-about-addresses/), and [the same is true of names](https://www.kalzumeus.com/2010/06/17/falsehoods-programmers-believe-about-names/). But even the _structure_ of this is wrong, when you think about it.
+
+A _physical place_, for our purposes, has an address. (It might have more than one.)
+
+Each place might play a number of _roles_ to a number of people: the same house is the home of everyone who lives there, and the same business address is one of the work addresses for each employee. If I work from home, my work and business addresses are the same. It's not quite true to say that an address is a "home": an address _identifies_ a _place_, and that place _is a home to a person_.
+
+But a typical contact application gets this wrong: the same _strings_ are duplicated (flattened and denormalized) into the independent contact records of each person. If a business moves location, or its building is renamed, we must change the addresses of multiple contacts.
+
+A more correct model for this is _relational_:
+
+```edn
+[:person/name             :db.type/string :db.cardinality/one]
+[:person/lives_at         :db.type/ref    :db.cardinality/many]    ; Points to a place.
+[:person/works_at         :db.type/ref    :db.cardinality/many]    ; Points to a place.
+[:place/address           :db.type/ref    :db.cardinality/many]    ; A place can have multiple addresses.
+[:address/mailing_address :db.type/string :db.cardinality/one      ; Each address can be represented once as a string.
+                          :db.unique/identity]
+[:address/city            :db.type/string :db.cardinality/one]     ; Perhaps this is useful?
+```
+
+Imagine that Alice works from home, and Bob works at his office on South Street. Alice's data looks like this:
+
+```edn
+[{:person/name "Alice Smith"
+  :person/lives_at "alice_home"
+  :person/works_at "alice_home"}
+ {:db/id "alice_home"
+  :place/address "main_street_123"}
+ {:db/id "main_street_123"
+  :address/mailing_address "123 Main St, Anywhere, WA 12345, USA"
+  :address/city "Anywhere"}]
+```
+
+and Bob's like this:
+
+```edn
+[{:person/name "Bob Salmon"
+  :person/works_at "bob_office"}
+ {:db/id "bob_office"
+  :place/owner "Example Holdings LLC"
+  :place/address "south_street_555"}
+ {:db/id "south_street_555"
+  :address/mailing_address "555 South St, Anywhere, WA 12345, USA"
+  :address/city "Anywhere"}]
+```
+
+Now if Alice (ID 1234) moves her business out of her house (1235) into an office in Bob's building (1236), we simply break one relationship and add a new one to a new place with the same address:
+
+```edn
+[[:db/retract 1234 :person/works_at 1235]     ; Alice no longer works at home.
+ [:db/add     1234 :person/works_at "new_office"]
+ {:db/id "new_office"
+  :place/address [:address/mailing_address "555 South St, Anywhere, WA 12345, USA"]}]
+```
+
+If the building is now renamed to "The Office Factory", we can update its address in one step, affecting both Alice's and Bob's offices:
+
+```edn
+[[:db/retract 1236 :address/mailing_address "555 South St, Anywhere, WA 12345, USA"]
+ [:db/add 1236 :address/mailing_address "The Office Factory, South St, Anywhere, WA 12345, USA"]]
+```
+
+You can see here how changes are minimal and correspond to real changes in the domain — two properties that help with syncing. There is no duplication of strings.
+
+We can find everyone who works at The Office Factory in a simple query without comparing strings across 'records':
+
+```edn
+[:find ?name
+ :where [?address :address/mailing_address "The Office Factory, South St, Anywhere, WA 12345, USA"]
+        [?office :place/address ?address]
+        [?person :person/works_at ?office]
+        [?person :person/name ?name]]
+```
+
+Let's say we later want to model move-in and move-out dates — useful for employment records and immigration paperwork!
+
+Trying to add this to the JSON model is an exercise in frustration, because there is no stable way to identify people or places! (Go ahead, try it.)
+
+To do it in Mentat simply requires defining a small bit of vocabulary:
+
+```edn
+[:place.change/person :db.type/ref :db.cardinality/many]
+[:place.change/from   :db.type/ref :db.cardinality/one]       ; optional
+[:place.change/to     :db.type/ref :db.cardinality/one]       ; optional
+[:place.change/role   :db.type/ref :db.cardinality/one]       ; :person/lives_at or :person/works_at
+[:place.change/on     :db.type/instant :db.cardinality/one]
+[:place.change/reason :db.type/string :db.cardinality/one]    ; optional
+```
+
+so we can describe Alice's office move:
+
+```edn
+[{:place.change/person 1234
+  :place.change/from   1235
+  :place.change/to     1237
+  :place.change/role   :person/works_at
+  :place.change/on     #inst "2018-02-02T13:00:00Z"}]
+```
+
+or Jane's sale of her holiday home:
+
+```edn
+[{:place.change/person 2468
+  :place.change/reason "Sale"
+  :place.change/from   1235
+  :place.change/role   :person/lives_at
+  :place.change/on     #inst "2018-08-12T14:00:00Z"}]
+```
+
+Note that we don't need to repeat the addresses, we don't need to change the existing data, and we don't need to complicate matters for existing code.
+
+Now we can find everyone who moved office in February:
+
+```edn
+[:find ?name
+ :where [?move :place.change/role :person/works_at]
+        [?move :place.change/on   ?on]
+        [(>= ?on #inst "2018-02-01T00:00:00Z")]
+        [(< ?on #inst "2018-03-01T00:00:00Z")]
+        [?move :place.change/person ?person]
+        [?person :person/name ?name]]
+```
+
+## Tend towards recording observations, not changing state
+
+These principles are all different aspects of normalization.
+
+The introduction of fine-grained entities to represent data pushes us towards immutability: changes are increasingly changing an 'arrow' to point at one immutable entity or another, rather than re-describing a mutable entity.
+
+In the previous example we introduced _places_ and _addresses_. Places and addresses themselves rarely change, allowing us to mostly isolate the churn in our data to the meaningful relationships between entities.
+
+Another example of this approach is shown in modeling browser history.
+
+Firefox's representation of history is, at its core, relatively simplistic; just two tables a little like this:
+
+```sql
+CREATE TABLE history (
+  id INTEGER PRIMARY KEY,
+  guid TEXT NOT NULL UNIQUE,
+  url TEXT NOT NULL UNIQUE,
+  title TEXT
+);
+
+CREATE TABLE visits (
+  id INTEGER PRIMARY KEY,
+  history_id INTEGER NOT NULL REFERENCES history(id),
+  type TINYINT,
+  timestamp INTEGER
+);
+```
+
+Each time a URL is visited, an entry is added to the `visits` table and a row is added or updated in `history`. The title of the fetched page is used to update `history.title`, so that `history.title` always represents the most recently encountered title.
+
+This works fine until more features are added.
+
+### Forgetting
+
+Browsers often have some capacity for deleting history. Sometimes this appears in the form of an explicit 'forget' operation — "Forget the last five minutes of browsing". Deleting visits in this way is fine: `DELETE FROM visits WHERE timestamp < ?`. But the mutability in the data model — title — trips us up. We're unable to roll back the title of the history entry.
+
+### Syncing
+
+But even if you are using Mentat or Datomic, and can turn to the log to reconstruct the old state, a mutable title on `history` will cause conflicts when syncing: one side's observed titles will 'lose' and be discarded in order to avoid a conflict. That's not right: those titles _were seen_. Unlike a conflicting counter or flag, these weren't abortive, temporary states; they were _observations of the world_, so there shouldn't be a winner and a loser.
+
+### Containers
+
+The true data model becomes apparent when we consider containers. Containers are a Firefox feature to sandbox the cookies, site data, and history of different named sub-profiles. You can have a container just for Facebook, or one for your banking; those Facebook cookies won't follow you around the web in your 'personal' container. You can simultaneously use separate Gmail accounts for work and personal email.
+
+When Firefox added container support, it did so by annotating visits with a `container`:
+
+```sql
+CREATE TABLE visits (
+  id INTEGER PRIMARY KEY,
+  history_id INTEGER NOT NULL REFERENCES history(id),
+  type TINYINT,
+  timestamp INTEGER,
+  container INTEGER
+);
+```
+
+This means that each container _competes for the title on `history`_. If you visit `facebook.com` in your usual logged-in container, the browser will run something like this SQL:
+
+```
+UPDATE TABLE history
+SET title = '(2) Facebook'
+WHERE url = 'https://www.facebook.com';
+```
+
+If you visit it in the wrong container by mistake, you'll get the Facebook login page, and Firefox will run:
+
+```
+UPDATE TABLE history
+SET title = 'Facebook - Log In or Sign Up'
+WHERE url = 'https://www.facebook.com';
+```
+
+Next time you open your history, _you'll see the login page title, even if you had a logged-in `facebook.com` session open in another tab_. There's no way to differentiate between the containers' views.
+
+The correct data model for history is:
+
+- Users visit a URL on a device in a container.
+- Pages are fetched as a result of a visit (or dynamically after load). Pages can embed media and other resources.
+- Pages, being HTML, have titles.
+- Pages, titles, and visits are all _observations_, and as such cannot conflict.
+- The _last observed_ title to show for a URL is an _aggregation_ of those events.
+
+The entire notion of a history table — a concept centered on the URL — having a title is a subtly incorrect choice that causes problems with more modern browser features.
+
+Modeled in Mentat:
+
+```edn
+[{:db/ident       :visit/visitedOnDevice
+  :db/valueType   :db.type/ref
+  :db/cardinality :db.cardinality/one}
+ {:db/ident       :visit/visitAt
+  :db/valueType   :db.type/instant
+  :db/cardinality :db.cardinality/one}
+ {:db/ident       :site/visit
+  :db/valueType   :db.type/ref
+  :db/isComponent true
+  :db/cardinality :db.cardinality/many}
+ {:db/ident       :site/url
+  :db/valueType   :db.type/string
+  :db/unique      :db.unique/identity
+  :db/cardinality :db.cardinality/one
+  :db/index       true}
+ {:db/ident       :visit/page
+  :db/valueType   :db.type/ref
+  :db/isComponent true                    ; Debatable.
+  :db/cardinality :db.cardinality/one}
+ {:db/ident       :page/title
+  :db/valueType   :db.type/string
+  :db/fulltext    true
+  :db/index       true
+  :db/cardinality :db.cardinality/one}
+ {:db/ident       :visit/container
+  :db/valueType   :db.type/ref
+  :db/cardinality :db.cardinality/one}]
+```
+
+Create some containers:
+
+```edn
+[{:db/ident :container/facebook}
+ {:db/ident :container/personal}]
+```
+
+Add a device:
+
+```edn
+[{:db/ident :device/my-desktop}]
+```
+
+
+Visit Facebook in each container:
+
+```edn
+[{:visit/visitedOnDevice :device/my-desktop
+  :visit/visitAt #inst "2018-04-06T18:46:00Z"
+  :visit/container :container/facebook
+  :db/id "fbvisit"
+  :visit/page "fbpage"}
+ {:db/id "fbpage"
+  :page/title "(2) Facebook"}
+ {:site/url "https://www.facebook.com"
+  :site/visit "fbvisit"}]
+```
+
+```edn
+[{:visit/visitedOnDevice :device/my-desktop
+  :visit/visitAt #inst "2018-04-06T18:46:02Z"
+  :visit/container :container/personal
+  :db/id "personalvisit"
+  :visit/page "personalpage"}
+ {:db/id "personalpage"
+  :page/title "Facebook - Log In or Sign Up"}
+ {:site/url "https://www.facebook.com"
+  :site/visit "personalvisit"}]
+```
+
+Now we can show the title from the latest visit in a given container:
+
+```edn
+.q [:find (max ?visitDate) (the ?title)
+    :where [?site :site/url "https://www.facebook.com"]

+# Project Mentat
+
+Project Mentat is a persistent, embedded knowledge base. It draws heavily on [DataScript](https://github.com/tonsky/datascript) and [Datomic](http://datomic.com).
+
+Mentat is implemented in Rust.
+
+The first version of Project Mentat, named Datomish, [was written in ClojureScript](https://github.com/mozilla/mentat/tree/clojure), targeting both Node (on top of `promise_sqlite`) and Firefox (on top of `Sqlite.jsm`). It also worked in pure Clojure on the JVM on top of `jdbc-sqlite`. The name was changed to avoid confusion with [Datomic](http://datomic.com).
+
+The Rust implementation gives us a smaller compiled output, better performance, more type safety, better tooling, and easier deployment into Firefox and mobile platforms.
+
+---
+
+## Motivation
+
+Mentat is intended to be a flexible relational (not key-value, not document-oriented) store that makes it easy to describe, grow, and reuse your domain schema.
+
+By abstracting away the storage schema, and by exposing change listeners outside the database (not via triggers), we hope to make domain schemas stable, and allow both the data store itself and embedding applications to use better architectures, meeting performance goals in a way that allows future evolution.
+
+## Data storage is hard
+
+We've observed that data storage is a particular area of difficulty for software development teams:
+
+- It's hard to define storage schemas well. A developer must:
+  - Model their domain entities and relationships.
+  - Encode that model _efficiently_ and _correctly_ using the features available in the database.
+  - Plan for future extensions and performance tuning.
+
+  In a SQL database, the same schema definition defines everything from high-level domain relationships through to numeric field sizes in the same smear of keywords. It's difficult for someone unfamiliar with the domain to determine from such a schema what's a domain fact and what's an implementation concession — are all part numbers always 16 characters long, or are we trying to save space? — or, indeed, whether a missing constraint is deliberate or a bug.
+
+  The developer must think about foreign key constraints, compound uniqueness, and nullability. They must consider indexing, synchronizing, and stable identifiers. Most developers simply don't do enough work in SQL to get all of these things right. Storage thus becomes the specialty of a few individuals.
+
+   Which one of these is correct?
+
+   ```edn
+   {:db/id          :person/email
+    :db/valueType   :db.type/string
+    :db/cardinality :db.cardinality/many     ; People can have multiple email addresses.
+    :db/unique      :db.unique/identity      ; For our purposes, each email identifies one person.
+    :db/index       true}                    ; We want fast lookups by email.
+   {:db/id          :person/friend
+    :db/valueType   :db.type/ref
+    :db/cardinality :db.cardinality/many}    ; People can have many friends.
+   ```
+   ```sql
+   CREATE TABLE people (
+     id INTEGER PRIMARY KEY,  -- Bug: because of the primary key, each person can have no more than 1 email.
+     email VARCHAR(64),       -- Bug?: no NOT NULL, so a person can have no email.
+                              -- Bug: nobody will ever have a long email address, right?
+   );
+   CREATE TABLE friendships (
+     FOREIGN KEY person REFERENCES people(id),  -- Bug?: no indexing, so lookups by friend or person will be slow.
+     FOREIGN KEY friend REFERENCES people(id),  -- Bug: no compound uniqueness constraint, so we can have dupe friendships.
+   );
+   ```
+
+   They both have limitations — the Mentat schema allows only for an open world (it's possible to declare friendships with people whose email isn't known), and requires validation code to enforce email string correctness — but we think that even such a tiny SQL example is harder to understand and obscures important domain decisions.
+
+- Queries are intimately tied to structural storage choices. That not only hides the declarative domain-level meaning of the query — it's hard to tell what a query is trying to do when it's a 100-line mess of subqueries and `LEFT OUTER JOIN`s — but it also means a simple structural schema change requires auditing _every query_ for correctness.
+
+- Developers often capture less event-shaped than they perhaps should, simply because their initial requirements don't warrant it. It's quite common to later want to [know when a fact was recorded](https://bugzilla.mozilla.org/show_bug.cgi?id=1341939), or _in which order_ two facts were recorded (particularly for migrations), or on which device an event took place… or even that a fact was _ever_ recorded and then deleted.
+
+- Common queries are hard. Storing values only once, upserts, complicated joins, and group-wise maxima are all difficult for non-expert developers to get right.
+
+- It's hard to evolve storage schemas. Writing a robust SQL schema migration is hard, particularly if a bad migration has ever escaped into the wild! Teams learn to fear and avoid schema changes, and eventually they ship a table called `metadata`, with three `TEXT` columns, so they never have to write a migration again. That decision pushes storage complexity into application code. (Or they start storing unversioned JSON blobs in the database…)
+
+- It's hard to share storage with another component, let alone share _data_ with another component. Conway's Law applies: your software system will often grow to have one database per team.
+
+- It's hard to build efficient storage and querying architectures. Materialized views require knowledge of triggers, or the implementation of bottleneck APIs. _Ad hoc_ caches are often wrong, are almost never formally designed (do you want a write-back, write-through, or write-around cache? Do you know the difference?), and often aren't reusable. The average developer, faced with a SQL database, has little choice but to build a simple table that tries to meet every need.
+
+
+## Comparison to DataScript
+
+DataScript asks the question: "What if creating a database were as cheap as creating a Hashmap?"
+
+Mentat is not interested in that. Instead, it's strongly interested in persistence and performance, with very little interest in immutable databases/databases as values or throwaway use.
+
+One might say that Mentat's question is: "What if an SQLite database could store arbitrary relations, for arbitrary consumers, without them having to coordinate an up-front storage-level schema?"
+
+(Note that [domain-level schemas are very valuable](http://martinfowler.com/articles/schemaless/).)
+
+Another possible question would be: "What if we could bake some of the concepts of [CQRS and event sourcing](http://www.baeldung.com/cqrs-event-sourced-architecture-resources) into a persistent relational store, such that the transaction log itself were of value to queries?"
+
+Some thought has been given to how databases as values — long-term references to a snapshot of the store at an instant in time — could work in this model. It's not impossible; it simply has different performance characteristics.
+
+Just like DataScript, Mentat speaks Datalog for querying and takes additions and retractions as input to a transaction.
+
+Unlike DataScript, Mentat exposes free-text indexing, thanks to SQLite.
+
+
+## Comparison to Datomic
+
+Datomic is a server-side, enterprise-grade data storage system. Datomic has a beautiful conceptual model. It's intended to be backed by a storage cluster, in which it keeps index chunks forever. Index chunks are replicated to peers, allowing it to run queries at the edges. Writes are serialized through a transactor.
+
+Many of these design decisions are inapplicable to deployed desktop software; indeed, the use of multiple JVM processes makes Datomic's use in a small desktop app, or a mobile device, prohibitive.
+
+Mentat was designed for embedding, initially in an experimental Electron app ([Tofino](https://github.com/mozilla/tofino)). It is less concerned with exposing consistent database states outside transaction boundaries, because that's less important here, and dropping some of these requirements allows us to leverage SQLite itself.
+
+
+## Comparison to SQLite
+
+SQLite is a traditional SQL database in most respects: schemas conflate semantic, structural, and datatype concerns, as described above; the main interface with the database is human-first textual queries; sparse and graph-structured data are 'unnatural', if not always inefficient; experimenting with and evolving data models are error-prone and complicated activities; and so on.
+
+Mentat aims to offer many of the advantages of SQLite — single-file use, embeddability, and good performance — while building a more relaxed, reusable, and expressive data model on top.

+<h1 class="title">How This API Document Is Organized</h1>
+<div class="subTitle">This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.</div>
+</div>
+<div class="contentContainer">
+<ul class="blockList">
+<li class="blockList">
+<h2>Package</h2>
+<p>Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:</p>
+<ul>
+<li>Interfaces (italic)</li>
+<li>Classes</li>
+<li>Enums</li>
+<li>Exceptions</li>
+<li>Errors</li>
+<li>Annotation Types</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Class/Interface</h2>
+<p>Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:</p>
+<ul>
+<li>Class inheritance diagram</li>
+<li>Direct Subclasses</li>
+<li>All Known Subinterfaces</li>
+<li>All Known Implementing Classes</li>
+<li>Class/interface declaration</li>
+<li>Class/interface description</li>
+</ul>
+<ul>
+<li>Nested Class Summary</li>
+<li>Field Summary</li>
+<li>Constructor Summary</li>
+<li>Method Summary</li>
+</ul>
+<ul>
+<li>Field Detail</li>
+<li>Constructor Detail</li>
+<li>Method Detail</li>
+</ul>
+<p>Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</p>
+</li>
+<li class="blockList">
+<h2>Annotation Type</h2>
+<p>Each annotation type has its own separate page with the following sections:</p>
+<ul>
+<li>Annotation Type declaration</li>
+<li>Annotation Type description</li>
+<li>Required Element Summary</li>
+<li>Optional Element Summary</li>
+<li>Element Detail</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Enum</h2>
+<p>Each enum has its own separate page with the following sections:</p>
+<ul>
+<li>Enum declaration</li>
+<li>Enum description</li>
+<li>Enum Constant Summary</li>
+<li>Enum Constant Detail</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Tree (Class Hierarchy)</h2>
+<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.</p>
+<ul>
+<li>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.</li>
+<li>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</li>
+</ul>
+</li>
+<li class="blockList">
+<h2>Deprecated API</h2>
+<p>The <a href="deprecated-list.html">Deprecated API</a> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p>
+</li>
+<li class="blockList">
+<h2>Index</h2>
+<p>The <a href="index-files/index-1.html">Index</a> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</p>
+</li>
+<li class="blockList">
+<h2>Prev/Next</h2>
+<p>These links take you to the next or previous class, interface, package, or related page.</p>
+</li>
+<li class="blockList">
+<h2>Frames/No Frames</h2>
+<p>These links show and hide the HTML frames.  All pages are available with or without frames.</p>
+</li>
+<li class="blockList">
+<h2>All Classes</h2>
+<p>The <a href="allclasses-noframe.html">All Classes</a> link shows all classes and interfaces except non-static nested types.</p>
+</li>
+<li class="blockList">
+<h2>Serialized Form</h2>
+<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.</p>
+</li>
+<li class="blockList">
+<h2>Constant Field Values</h2>
+<p>The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.</p>
+</li>
+</ul>
+<span class="emphasizedPhrase">This help file applies to API documentation generated using the standard doclet.</span></div>
