Re: making our HTML+RDFa queryable


RDFa "extends" RDF .... as in "embrace, extend, extinguish".  OK, all RDFa really does is Brand an attribute label with less actual work than the maintenance of an XML Schema.  Engineering to be different is a game lazy, bored Engineers play and the whole HTML family can play for decades.

 I the documents would be
 using XHTML instead of HTML, you could parse
 the RDFa metadata using a simple XSLT
 stylesheet. Yet the browser
 vendors went for
 HTML5 and made parsing hard.
 Interestingly, those are the same companies
 that are able to harvest
 documents on Web
 scale, write own parsers, and manage large graphs of
 structured data.
 We are giving away the dog food yet have a hard
 time eating it
 ourselves. Which brings us
 back to the need for decentralization.
