I think a lot is available already, so what we mainly need is probably mainly a "suggested vocabulary blend": * type * rss:item * sioc:MicroblogPost * all typical rss properties * rss:title * rss:description * content:encoded * dc:subject (hashtags) * dc:creator for the author name * author stuff * dct:creator for author resource (profile vs person issue?) * sioc:has_creator for author profile/account URL * sioc:avatar / atom:link * links * dct:references (short or expanded? prolly the latter) * Semweb URIs * dct:subject * threads * sioc:reply_of What's missing (not sure which are really useful or possible): * type * ex:DirectMessage * ex:ReTweet * targetUser (@user) * mentioned user (... @user) * referred by ( ... via @user) * machine/triple tags? * derived stats? * number of re-tweets * number of url posts * client app (needed? there's twitter:source, but has html) * ratings (if so, which notation?) * group (identi.ca uses !group, but doesn't have rdf, I think) Benji -- Benjamin Nowack http://bnode.org/ http://semsol.com/ > >Cheers, > Michael > >-- >Dr. Michael Hausenblas >LiDRC - Linked Data Research Centre >DERI - Digital Enterprise Research Institute >NUIG - National University of Ireland, Galway >Ireland, Europe >Tel. +353 91 495730 >http://linkeddata.deri.ie/ >http://sw-app.org/about.html > > > >> From: Benjamin Nowack <bnowack@semsol.com> >> Organization: semsol.com >> Reply-To: Benjamin Nowack <bnowack@semsol.com> >> Date: Mon, 28 Sep 2009 11:35:53 +0200 >> To: Semantic Web community <semantic-web@w3.org> >> Subject: tweet2rdf vocabulary convergence >> Resent-From: Semantic Web community <semantic-web@w3.org> >> Resent-Date: Mon, 28 Sep 2009 09:36:31 +0000 >> >> >> Hi, >> >> Morton Swimmer suggested that there might be broader interest to talk >> a bit about RDF extracted from tweets, so here we go: >> >> There are multiple tools and services that convert twitter profiles >> and contacts to RDF (e.g semantictweet[1] or knowee), I think they all >> mostly re-use stuff from FOAF and don't really need new terms. >> >> But there are also tools that convert individual tweets to RDF >> (I think Tom Morris had code. smesher is another example), or the >> other way round (e.g. SMOB).
