Mulgara is a scalable RDF database written entirely in Java. It is an Open Source fork of Kowari.

Redland is a set of free software libraries that provide support for the Resource Description Framework (RDF).

Kowari is an Open Source, massively scalable, transaction-safe, purpose-built database for the storage, retrieval and analysis of metadata.

It provides access to the RDF data via RDQL or SPARQL over HTTP, on the command line or via a C API.

3store is a core C library that uses MySQL to store its raw RDF data and caches.

Einen Schwerpunkt bilden dabei Soziale Lesezeichensysteme, wie bsp. unser BibSonomy-System. Ein weiteres Thema sind Peer-to-Peer-Netze. Neben Projekten in denen inhaltliche Fragestellungen im Vordergrund stehen, bieten wir auch die Möglichkeit, aktuelle Techniken aus dem Bereich des Web 2.0 wie z.B. Ajax in Projekten anzuwenden und in laufende Systeme zu integrieren.

It takes a practical approach by targeting the work to the needs of developers, answering frequently asked questions related to this subject. The report first reviews previous work in surveying semantic web data, schema and triple stores, then gives an overview of the major systems with their feature set and maturity and then uses that information to provide a set of FAQs with answers related to storing semantic web data.
