Interface NamespaceSupport

All Known Subinterfaces:

Model, ModelSet

public interface NamespaceSupport

This interface leaves it open to implementations where the prefixes go, e.g. if prefixes added to a Model change the mapping in the surrounding ModelSet if any. As namespaces do not really exist *in RDF*, only in syntaxes, there are no definitive specifications on this subject. This API is modeled after the OpenRDF 2.0 API.
