 - [ ] Support sparse fieldsets. At the moment, not sure what this support will look like. A client can likely just define a new model to represent a sparse population of another model in a very specific use case. On the server side, it becomes much more appealing to be able to support arbitrary combinations of omitted fields.

 - [x] Only allow `TransformedAttribute` and its derivatives as stored properties within `Attributes` struct. Computed properties can still be any type because they do not get encoded or decoded.

-## JSONAPITestLib
-The `JSONAPI` framework is packaged with a test library to help you test your `JSONAPI` integration. The test library is called `JSONAPITestLib`. It provides literal expressibility for `Attribute`, `ToOneRelationship`, and `Id` in many situations so that you can easily write test `Entity` values into your unit tests. It also provides a `check()` function for each `Entity` type that can be used to catch problems with your `JSONAPI` structures that are not caught by Swift's type system. You can see the `JSONAPITestLib` in action in the Playground included with the `JSONAPI` repository.

+# JSONAPI+Arbitrary
+The `JSONAPIArbitrary` framework adds `Arbitrary` support via `SwiftCheck`. With a little extra work on your part, this framework will allow you to create "arbitrary" (i.e. randomly generated) instances of your JSONAPI entities, includes, documents, etc.
+
+This library does not offer full support of all `JSONAPI` types yet. The documentation will grow as the framework becomes more complete.
+
+# JSONAPI+OpenAPI
+The `JSONAPIOpenAPI` framework adds the ability to generate OpenAPI compliant JSON documentation of a JSONAPI Document.
+
+This library is in its infancy. The documentation will grow as the framework becomes more complete.
