  • 2. SMOBDigital Enterprise Research Institute www.deri.i e  Open source microblogging framework  Data is modelled and exchanged using Semantic Web standards (RDF(S) and SPARQL) and Linked Data principles  Relies on protocols emerging from Social Web systems (RSS, PubSubHubbub, WebSockets) 2
  • 3. Linked Data for the Social WebDigital Enterprise Research Institute www.deri.i e  Combines several vocabularies such as FOAF, SIOC, MOAT / CommonTag or OPO  Advantages:  Application-agnostic  Interlinking to social data  Meaningful representation of topics  Disambiguate tags  Transparent to the user 3

  • 5. PublishingDigital Enterprise Research Institute www.deri.i e  Since PuSH does not support RDF, we encode SPARQL 1.1 Update queries in the RSS feeds  Web Sockets are also added to allow client-to- server communication 5
  • 6. The privacy challengeDigital Enterprise Research Institute www.deri.i e  The WebID protocol and the Privacy Preference Ontology (PPO) allow authentication and access control  The process is transparent to the user 6
