Group: OpenRDF Alibaba

Provides an in-memory index of RDF statements.

The Object Repository maps Java objects to and from RDF resources and OWL classes to Java classes in a non-intrusive manner that enables developers to work at the object level.

Auditing SAIL

The Optimistic Repository provides concurrent optimistic serializable transactions for embedded Sesame Sails.

Provides an on disk key store of RDF file streams.

Adds named query storage to a Sesame Repository.

The Object Server is a general purpose HTTP persistence store. It combines an key/value store with an RDF store to provide storage and retrieval with searchable metadata.

The Federation SAIL allows multiple datasets to be virtually combined into a single dataset. The Federation SAIL combines multiple RDF stores that may exist on a remote server or are embedded in the same JVM. The Federation uses query optimizations to distribute sections of the query to different members based on the data contained in each of the members. These results are then joined together within the federation to provide the same result as if all the data was co-located within a single repository.

The SPARQL Repository provides a read-only Sesame Repository interface to any SPARQL end-point.

The Object Composition library merges multiple Java objects into a single multi-subject object.

Runtime dependencies for an OpenRDF application

Auditing Repository

Boolean match of resource by keywords in configurable properties.

AliBaba is a collection of modules that provide simplified RDF store abstractions to accelerate development and facilitate application maintenance.

The Metadata Server is a general purpose HTTP persistence store. It combines an key/value store with an RDF store to provide general purpose storage and retrival with searchable metadata.
