Not asking you to mix them. Saying, look at how we deal with it via <link/> relations, for instance.
Re. URIBurner, note its ability to produce both RDFa and Microdata from the RDF it negotiates. Ditto JSON-LD :-)It's really cool that there's RDFa in the generated URIBurner code! However, I could find no Microdata embedded into the HTML (e.g. a search for "itemprop" returns empty): $ curl -s http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fvocab.e.gov.br%2F2011%2F03%2Fvcge%23imigrantes | grep itemprop
Look at the footer of a URIBurner page. Or look in <head/> or look at the "Link:" response headers re. alternative representation formats .
Is a particular parameter required in order to return HTML5 + Microdata from URIBurner? I found that adding a parameter output=application%2Fmicrodata%2Bjson to the URL does return data in the application/microdata+json format, but I found no way to get it embedded into HTML. Also, about the generated RDFa, I found this bit a little strange (intentation added by myself): <body about="http://vocab.e.gov.br/2011/03/vcge#imigrantes";> ... <ul class="obj"> <li> <span class="literal"> <!-- 43 --> <a class="uri" rel="rdf:type" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; href="/describe/?url=http%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23Concept">Concept</a> </span> </li> </ul> ... </body> This produces the following triple (see RDFa distiller [1]): <http://vocab.e.gov.br/2011/03/vcge#imigrantes> a <http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23Concept> . Shouldn't the type be just <http://www.w3.org/2004/02/skos/core#Concept>, as asserted in the source material, instead of escaping the URL around URIBurner?
