  1. 1. Digital Enterprise Research Institute www.deri.i e SMOB: The best of both worlds Alexandre Passant, Julia Anaya, Owen Sacco, Pavan Kapanipathi FSW2011 Saturday, 4th June 2011 Berlin, Germany© Copyright 2010 Digital Enterprise Research Institute. All rights reserved.
  2. 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. 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
  4. 4. ArchitectureDigital Enterprise Research Institute www.deri.i e PubSubHubBub (PuSH) is an open, server-to- server pubsub (publish/subscribe) protocol as an extension to Atom and RSS 4
  5. 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. 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
  7. 7. Access controlDigital Enterprise Research Institute www.deri.i e 7
  8. 8. SummaryDigital Enterprise Research Institute www.deri.i e  Discussed how a combination of Semantic Web standards and pragmatic Social Web protocols could be benficial to achieve the Federated Social Web vision  Implemented privacy-by-design in SMOB http://smob.me, https://github.com/smob/smob alexandre.passant@deri.ie julia.anaya@deri.ie, owen.sacco@deri.ie, pavan.kapanipathi@deri.org 8
