Global *S*emantic *C*ategory, *O*ntology, *T*ag and *T*axonomy S*y*stem, adding OWL based services as well as simple categories, tags and tagclouds. Relations are made using real SQL relations, that can be exported later on to OWL and other standards. This will enable exchange of semantic information between different systems.
The SIOC initiative (Semantically-Interlinked Online Communities) aims to enable the integration of online community information. SIOC provides a Semantic Web ontology for representing rich data from the Social Web in RDF. It has recently achieved significant adoption through its usage in a variety of commercial and open-source software applications, and is commonly used in conjunction with the FOAF vocabulary for expressing personal profile and social networking information. By becoming a standard way for expressing user-generated content from such sites, SIOC enables new kinds of usage scenarios for online community site data, and allows innovative semantic applications to be built on top of the existing Social Web. The SIOC ontology was recently published as a W3C Member Submission, which was submitted by 16 organisations.
