SMOB

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)

3


Linked Data for the Social Web

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

4


Architecture

PubSubHubBub (PuSH) is an open, server-to-server pubsub (publish/subscribe) protocol as an extension to Atom and RSS

5


Publishing

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

6


The privacy challenge

The WebID protocol and the Privacy Preference Ontology (PPO) allow authentication and access control

The process is transparent to the user

7


Access control

8


Summary

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
