From Online Community Data to RDF
Large amounts of data are created within online community sites (forums, blogs, etc.). These can serve as a valuable source of information for web users, and usually contain rich meta-information. Most of this information is stored in relational databases, but unfortunately remains locked into these databases and cannot be used by other applications. The SIOC project is aimed at providing guidelines for making this information available on the Web and for using this information for connecting online community sites together. SIOC aims to let other sites know more about the structure and contents of online communities, and to make more use of tagging and semantic metadata in these sites.
