Hi!We've recently added some examples on how to mark up web pages using our controlled vocabulary for e-gov (Vocabulário Controlado de Governo Eletrônico - VCGE). The examples include HTML5 + RDFa 1.1, HTML5 + RDFa Lite 1.1 and HTML5 + Microdata, and we'd like to check if it's correct. For instance, if a webpage is about Education, it would be marked up like this: <!DOCTYPE html> <html> <head> <title>Página sobre Educação</title> <meta property="http://purl.org/dc/terms/subject"; content="http://vocab.e.gov.br/2011/03/vcge#educacao"; /> ... </head> ... </html> Since there's no "about" attribute to set the subject in this example, it is assumed to be the current document. Thus, the following triple would be generated: <> dcterms:subject<http://vocab.e.gov.br/2011/03/vcge#educacao> . In RDFa Lite, we followed the example set in its current draft document by using schema.org: <!DOCTYPE html> <html> <head> <title>Página sobre Educação</title> <meta vocab="http://schema.org/"; property="about" content="http://vocab.e.gov.br/2011/03/vcge#educacao"; /> ... </head> ... </html> I think this would generate the following triple: <> <http://schema.org/about> <http://vocab.e.gov.br/2011/03/vcge#educacao> .. Finally, using Microdata, we can't just assume the current document is the subject like in RDFa, and the itemscope has to be set explicitly; The empty itemid would indicate the current document: <!DOCTYPE html> <html> <head itemscope itemtype="http://schema.org/WebPage"; itemid=""> <title>Página sobre Educação</title> <meta itemscope itemprop="about" content="http://vocab.e.gov.br/2011/03/vcge#educacao"; /> ... </head> ... </html> I checked the URL with Google Rich Snippets and it did indeed find the Microdata item like this (the page is marked up using both RDFa 1.1 and Microdata): Item http://schema.org/about = http://vocab.e.gov.br/2011/03/vcge#esquema You can check how our controlled vocabulary is presented as well as the examples in the following URL: http://vocab.e.gov.br/2011/03/vcge Comments, suggestions, and especially corrections are welcome.

All conforming RDFa parsers will understand @rev and your example is just fine. Alternatively, you could reverse and use@about and duplicate the web page address in @href ursine either @property or @ref instead of @rev, but this is the case that @rev was created to address.

Happy New Year to everyone!Could you provide URLs to each of the HTML5 resource types? That makes verification and bug identification much easier.
