I’m currently learning/exploring RDFa (try searching my blog for “rdfa”). As a total newbie to the world of RDF and RDFa, these tools and resources have been helpful so far:
First, the W3C RDFa 1.1 Primer is easy reading, a great introduction to RDFa. And it links to the full specifications (which are also well-written).
The W3C RDFa 1.1 Distiller and Parser is a Web page where you enter a URL, then it summarizes the RDFa data it finds there. Good for verifying your own Web site’s RDFa. (Or try it with one of my blog posts or my home page, http://www.strehle.de/tim/ …)
If you’re like me and prefer to analyze your RDFa from the command line, install the pyRdfa distiller/parser library and run “scripts/localRDFa.py -p URL” (-p means RDF/XML output).
RDFa / Play is a Web page where you type in HTML+RDFa code and, as you type, see it turned into a pretty graph visualization. Nice for playing around with the RDFa syntax.
I’m trying to use common vocabulary if possible, often from the schema.org hierarchy.
Of course, the nice thing about RDFa is that you can always “view source” on other’s pages to see what they’re doing.
Are you into RDFa? Please let me know if I’m missing out on something!
