## Uses of Interface
org.modeshape.jcr.query.validate.Schemata

- Packages that use Schemata
  Package | Description
  --- | ---
  org.modeshape.jcr |
  org.modeshape.jcr.query | The Query API provides a mechanism for building and executing queries.
  org.modeshape.jcr.query.lucene | The core query engine, which currently uses Lucene for indexing and raw queries, and the Hibernate Search engine (which does not depend on or use Hibernate Core or JPA) for updating and querying the Lucene indexes.
  org.modeshape.jcr.query.process | This package defines the `QueryProcessor` interface, which is responsible for constructing for each query a tree of `ProcessingComponent` objects that each are responsible for processing a specific aspect of the query and returning the tuples to the parent component.
  org.modeshape.jcr.query.validate | This package provides the interfaces that define the tables and columns that can be queried.
