The Web of Linked Data

The goal of the semantic web / linked data movement is tomake the content of the web more usable by machines.But the web evolves continuously.

The added value of linked data

specialising the vocabulary

e.g. deriving subproperties of sioca:object with verbsfrom activitystrea.ms

linking actions to the LOD cloud

e.g. DBpedia concepts for Wikipedia pagese.g. a SVN commit to the bug it solvese.g. tracking provenance of UGC

linking actions from the LOD cloud

anybody can add information about actionse.g. “like” button for actions?

Conclusion

actions are becoming first class citizens of the social webthe web of linked data can leverage the potential ofaction-based applicationswe propose a vocabulary and a translation service toachieve that
