Class SailRepository

java.lang.Object

org.openrdf.repository.base.RepositoryBase

org.openrdf.repository.sail.SailRepository

All Implemented Interfaces:

Repository

public class SailRepository
extends RepositoryBase

An implementation of the Repository interface that operates on a (stack of) Sail object(s). The behaviour of the repository is determined by the Sail stack that it operates on; for example, the repository will only support RDF Schema or OWL semantics if the Sail stack includes an inferencer for this.

Creating a repository object of this type is very easy. For example, the following code creates and initializes a main-memory store with RDF Schema semantics:

 Repository repository = new SailRepository(new ForwardChainingRDFSInferencer(new MemoryStore()));
 repository.initialize();
 

Or, alternatively:

 Sail sailStack = new MemoryStore();
 sailStack = new ForwardChainingRDFSInferencer(sailStack);
 
 Repository repository = new SailRepository(sailStack);
 repository.initialize();
