public interface ModelQuerySession extends OsidSession

This session provides methods for searching among Models . The search query is constructed using the ModelQuery .

This session defines views that offer differing behaviors for searching.

  • federated warehouse view: searches include models in warehouses of which this warehouse is an ancestor in the warehouse hierarchy
  • isolated warehouse view: searches are restricted to models in this warehouse

Models may have a query record indicated by their respective query record types. The query record is accessed via the ModelQuery .
