[Mulgara-dev] Sesame and Mulgara Integration

[Paul Gearon]

Announced today:  http://zepheira.com/news/releases/20080516.html

FREDERICKSBURG, Virginia, 15 May, 2008-Aduna and Zepheira, LLC
announced today that the Sesame RDF framework now supports the storage
of RDF data in the Mulgara Semantic Store.

Aduna has released Sesame version 2.2 Beta1, which includes support
for the Mulgara storage layer. Production releases are being finalized
now and are expected later this summer.

Sesame is an Open Source Java framework for the storage, inferencing
and querying of Resource Description Framework (RDF) data. The
framework is extensible and configurable with respect to storage
mechanisms, inferencers, RDF file formats, query result formats and
query languages. Sesame supports the SPARQL RDF query language, which
became a standard of the World Wide Web Consortium in January, 2008
and Aduna's own SeRQL query language. SeRQL provides advanced features
not yet available in SPARQL. Sesame offers a JBDC-like user API,
streamlined system APIs and a RESTful HTTP interface supporting the
SPARQL Protocol for RDF.

Sesame version 2.1 added support for storing RDF data in relational
databases. MySQL and PostgreSQL were supported in March, 2008. As of
this release, Sesame also includes support for Mulgara, the most
scalable of the native RDF data stores.

Mulgara is a native RDF database, written in Java and designed to
scale to hundreds of millions of RDF statements. Current work on
Mulgara aims to increase its storage capacity to hundreds of billions
of RDF statements by June of 2009. Aduna and Zepheira backed the
integration of Mulgara and Sesame to provide Sesame's users with a
single API for RDF data, regardless of the amount of data involved.

"Sesame developers may now work with the same API to manage their RDF
data, from small in-memory prototypes to the largest enterprise
projects," said Arjohn Kampman, Sesame's lead developer at Aduna.
Ralph Pere, Aduna CEO, said, "Aduna remains committed to providing
Sesame developers with the widest range of scalability options."

David Wood, a Zepheira partner and Mulgara project member, said,
"Zepheira is pleased to facilitate the integration of Mulgara and
Sesame. We see tremendous value in the integration of the projects,
their developers and their communities of users. Industry coalescence
around the SPARQL query language, the SPARQL protocol and the SAIL API
will ease the transition of legacy systems onto the Web of Data."

"The integration of Sesame and Mulgara has brought together two of the
leading Open Source Semantic Web frameworks. The comprehensive set of
APIs and standards from Sesame along with the scalability and speed of
Mulgara gives developers a single port of call for Semantic Web
projects of all levels. We have now combined the experience and skills
of the developers from both projects, giving us much greater capacity
for ongoing development than when our efforts were split between
unrelated systems," said Paul Gearon, founder and leader of the
Mulgara Project.
