RDFa for Semantic MediaWiki [GSoC 2008]

David McCabe, July 1st, 2008

Hello, world!

My name is David McCabe, and this summer I am adding RDFa support to Semantic MediaWiki, as part of the Google Summer of Code 2008. I am an undergraduate in Mathematics at Portland State University. For the Google Summer of Code 2006, I wrote Liquid Threads, a MediaWiki extension that replaces talk pages with a threaded discussion system.

Semantic MediaWiki (SMW) is the software used for the CC wiki and many other wikis. SMW allows authors to mark up wiki pages so that their contents and relationships are machine-readable. SMW already publishes this machine-readable data in RDF/XML format.

You can read about RDFA on the CC Wiki. There is also a Google Tech Talk on RDFa.

Metadata work of interest

Mike Linksvayer, August 3rd, 2007

Some of these could turn out to be interesting for describing licensed content on the web, all rather interesting.

hAudio proposed microformat.

Proposed hAudio to RDFa mapping.

RDFa-deployed Multimedia Medata (ramm.x) may be an effort to map and standardize use of existing and upcoming media description standards in RDFa … I had to skim “ramm.x in 10 sec” and “what ramm.x is NOT” a few times to gather that, but the key description on that page seems to be:

Does ramm.x replace RDF-based multimedia vocabularies, as, e.g., the Music Ontology Specification?

No! ramm.x aims at bringing existing formats, as MPEG-7 and the like, into the Semantic Web. It acts as a bridge using a certain formalisation of an existing vocabulary.

Getting a bit more esoteric, Protocol for Web Description Resources (POWDER):

facilitates the publication of descriptions of multiple resources such as all those available from a Web site.

Which is a bit of an understatement.
