All Implemented Interfaces:

Serializable

public class SchemaSchema

extends Schema

This is the schema for all documents that have persistent schemas on them. This schema is used to remember what other schemas are in effect.

The SchemaSchema lets a document persistently remember what schemas have been applied to it. AddSchema(), removeSchema(), etc should all muck with properties under this schema.

There are many possible ways to implement this. One could have the schema list be names which refer to singleton documents that persistently represent *particular* schemas (for example, a document that represents the fields of the ContentSchema or the ResourceSchema).

But currently our schemas are all "pure code," so I haven't taken this approach. Instead, the SchemaSchema remembers the fully-qualified class names of the SchemaDescriptors used to generate the schemas that are applied to it.

This may change in the future...
