As John Breslin already detailed last week, we (Tuukka Hastrup, Uldis Bojars, John and myself) recently work on SMOB, a semantic microblogging architecture, that will be presented at next SFSW workshop, co-located with ESWC in Tenerife.
While there have been a lot of buzz recently regarding ways to provide open alternatives to Twitter, then fun thing is that we worked on this in last January while I visited DERI. Our main goal was to show how Semantic Web technologies could provide an open-platform for such way of publishing content, mainly using FOAF and SIOC. Moreover, one of our aim was also to demonstrate how such technologies can provide users a way to control, share and remix their data as they want, not depending on a third-party service, a goal also shared by the dataportability project. In that way, SMOB-published data really belongs to the user that wrote it. Indeed, while SMOB servers (which display a faceted view of agregated posts as you can see on the demo server) store data in their local triple-store, this information (i.e. each update) is hosted on the client side and available in RDF.
At the moment, the complete updates dataset is public, and can be browsed with any RDF browser as the picture below shows (with Tabulator) but we plan to introduce more advanced authentication and privacy issues, in which OpenID could have a role to play.
Users can parse it as any RDF data, mash-it up with other information, eg their FOAF profile (SMOB allows to re-use existing FOAF profile as the
foaf:maker of each update), or any other RDF data. And most important, if a SMOB server closes, they still own their data.
Moreover, since SMOB content is SIOC-based, it becomes part of the SIOC-o-sphere, and could be merged with your other social media contributions (from any SIOC application) and discovered thanks to recent APIs and WordPress plug-in introduced by Sindice (automatic PTSW / Sindice pings will be soon in the code repository). This is one more advantage of getting a common semantics to model your data wherever they come from.
Finally, we just introduced in SMOB a way to publish not only to a dedicated server, but also to Twitter. So that you’ll get a real-time, self-hosted and long-life archive of your twits in RDF. Isn’t that cool ?
