13. Digital Enterprise Research Institute www.deri.ie Using the Ontology Building Application Eco-System –“Bootstrap” the use of the ontology Cover the main parts of the information life-cycle –Data Creation –Data Integration –Using the Data http://rdfs.org/sioc/applications/ 13

14. Digital Enterprise Research Institute www.deri.ie SIOC Application Eco-System 14

15. Digital Enterprise Research Institute www.deri.ie Growing the Eco-System (1) Initial SIOC applications created in DERI: –SIOC export plugins for Drupal, Wordpress –Semantic Radar for Firefox –SIOC browsers, [Social] SIOC Explorer Built by the community: –SIOC APIs (Java, Perl, …) –SWAML –KiWi –Talis Aspire –Drupal 7 (RDFa) http://www.youtube.com/watch?v=r4WgTRIRoa0 15

16. Digital Enterprise Research Institute www.deri.ie Growing the Eco-System (2) 16 http://wiki.sioc-project.org/w/ApplicationTimeline Total: 54 apps – In DERI - 21 – By a larger community - 33

17. Digital Enterprise Research Institute www.deri.ie Applications of SIOC

18. Digital Enterprise Research Institute www.deri.ie 18 Social Data Portability with SIOC Importing SIOC data: –Parse SIOC RDF data (e.g. using ARC2 or RAP for PHP) –Convert SIOC data to the content model of the target system: e.g. content and other properties of blog posts and comments –Store data in the target application Wordpress plugin

27. Conclusion

28. Digital Enterprise Research Institute www.deri.ie Summary SIOC Ontology –A standard format for expressing Social Web data in RDF Applications of SIOC –Covering all parts of the data life cycle You and the SIOC project –Use it ! (data and applications) –Participate ! (it’s an open, distributed project) –Create new ideas ! 28
