## Package org.modeshape.graph.query.validate Description

This package provides the interfaces that define the tables and columns that can be queried. Though the query framework does not prescribe the semantics of a table or column, it does provide a `Schemata` interface that provides access to the immutable `Schemata.Table` and `Schemata.View` definitions (that then contain the `Schemata.Column` and `Schemata.Key` definitions).

Although any Schemata implementaiton can be used, the query framework provides an `ImmutableSchemata` class with a `builder` with a fluent API that can create the corresponding immutable table, column and key definitions.
