This report surveys the state of semantic web storage for RDF / triple data using existing free software tools. 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.
Why Dog Food?!
The call to "eat your own dog-food" is often heard in the Semantic Web research area. The motto encourages us to use the languages and tools that we are developing to support our own work and demonstrate convincing arguments for the introduction of explicit semantics.
The International Semantic Web and European Semantic Web Conference series have followed this maxim and published metadata describing the events. This metadata covers information about papers, schedules, attendees etc. Tools can then consume this information and provide services, such as intelligent scheduling or search, to conference attendees.
