SIOC
From eg
The SIOC project .org is an attempt to find a common ontology for Semantically-Interlinked Online Communities. The name alone has caused the project to fail but it is notable for actually helping to outline needs for such a project:
- any such ontology requires a scoped specification, namespaces and mappings between these
- the tools that must be supported include at least
- exporters
SIOC claims to provide "methods for interconnecting discussion methods such as blogs, forums and mailing lists to each other. It consists of the SIOC ontology, an open-standard machine readable format for expressing the information contained both explicitly and implicitly in internet discussion methods, of SIOC metadata producers for a number of popular blogging platforms and content management systems, and of storage and browsing / searching systems for leveraging this SIOC data." It is "hosted at DERI, NUI Galway and supported by SFI under Grant No. SFI/02/CE1/I131. "
[edit] vs. microformats
The cite-rel draft by Ryan King and Eran Globen may be irreconcilable with semantic-web-centric approaches like SIOC. According to 'user 1' who calls himself 'Cloud', "there is no good reason that both the Semantic Web and Microformats communities can't work together... There are people on both sides who strongly feel that the other is going in the wrong direction, but it would be a mistake to let any such voices dominate. Both communities are trying to add semantics in the Web, and using things like GRDDL and Micromodels / mf RDF representations, the existing work from both sides can be reused."
[edit] vs. FOAF
The SIOC concept of a user (called correctly SIOC:user) may overlap with FOAF:person). A foaf:Person however "can own many sioc:User profiles (via the foaf:holdsOnlineAccount relationship)." There are also obvious connections with SKOS.
