Solving the use case
Tracking an emerging music community over time Question: What is happening in the Dubstep scene
in Dublin? Solutions that do not work:
Google:– Sites updated too frequently– Bad results: new and relevant pages get buried due to ranking
RSS: – not all types of sites have RSS– RSS feeds do not include all relevant information

Details: the SIOC ontology
SIOC allows re-using the data at the center of a community: content:
– blog and forum posts– wiki pages– freeform text (new types can be defined)
topics: – tags and categories– complex hierarchies possibly with SKOS
user relations:
FOAF and openID identities
the next SIOC version will be geared towards major social networking sites and Web 2.0 hub sites

Exploring SIOC data
SIOC Explorer crawls and aggregates SIOC data allows exploring and browsing
– filter by topic– view posts of a certain day
Implements faceted browsing step-wise filtering of displayed content filtering works across sites
