Noticed this is my referrers this morning: Semantic Collaboration "seco is a system to enable collaboration in online communities. It collects RDF data from the web, stores it in an index, and makes it accessible via a web interface. At the moment the system contains information about more than 7000 people and 2000 news items. This represents most of the information on the emerging semantic web in FOAF and RDF 1.0 vocabularies. This data has been created by a large number of people. The challenge is to tidy up this data and integrate it in a way that facilitates easy access and re-use."
