I'd like to add a note on representing data *embedded in* tweets, as opposed to data strictly *about* tweets. As I see it, there are a few distinct kinds of structured data to be gotten from Twitter: 1) Twitter-generated data about users 2) Twitter-generated data about tweets 3) user-embedded data about tweets 4) user-embedded data about everything else Most of this thread has been about bits of vocabulary for expressing #1 and (especially) #2: authoritative information about Twitter users and individual microblog posts provided by Twitter through its API, RSS feeds, etc. #3 is also about individual microblog posts, but requires some trust in the user who embeds the data and the parser which interprets it. #4 is data about *anything* -- the location of an airport, whether or not you like Obama, the fact that @romeo loves @juliet, etc. -- expressed in general-purpose formats like Twitter Data and MicroTurtle. So... I'd like to suggest that this vocab cloud should also include a property for the relationship between user-generated information and the tweets it is derived from: something like the Web of Belief ontology's "hasSourceDocument" (which relates a graph reference with a Semantic Web document) but with a range of sioc:Post, foaf:Document or such, so an application like mine can link up user-generated descriptions with tweets described by some of these other services. Having looked through a few provenance-related ontologies (WOB Core, PML Trust, CWM Reason), I have not yet seen anything that entirely fits. Thoughts?
