Not asking you to mix them. Saying, look at how we deal with it via<link/>

relations, for instance.

Yes, that's a very nice thing at URI burner! We intend to include it
soon in the VCGE resource as well.

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

"Link:" response headers re. alternative representation formats .

Look at the footer of a URIBurner page. Or look in<head/> or look at the

Do you mean this link at line 35?

<link href="http://linkeddata.uriburner.com/sparql?query=define%20sql%3Adescribe-mode%20%22LOD%22%20%20DESCRIBE%20%3Chttp%3A%2F%2Fvocab.e.gov.br%2F2011%2F03%2Fvcge%23imigrantes%3E&amp;output=text%2Fhtml";

rel="alternate" type="text/html"  title="Structured Descriptor
Document (HTML+Microdata format)" />

Despite what the title says, the linked document [1] does not seem to
contain any embedded Microdata. See [2].

Then its a bug!

I'll have it looked into.

Augusto,



1. http://linkeddata.uriburner.com/c/IA47SB -- query results

Looking into this matter further, this time going directly to the SPARQL endpoint which is basically the handler for the URLs used across <link/>, "Link:", and footer links. 2. http://linkeddata.uriburner.com/c/IA47SH -- query text in the HTML editor associated with the sparql endpoint.

Now I need to find out why that isn't in the footer .

Augusto,

I forgot to add this Google snippets link re. item #1: http://uriburner.com/c/IBJW3O .

How did you arrive at this problem via either of these URIBurner pages:

1. http://linkeddata.uriburner.com/about/html/http://vocab.e.gov.br/2011/03/vcge%01imigrantes 2. http://linkeddata.uriburner.com/describe/?uri=http%3A%2F%2Fvocab.e.gov.br%2F2011%2F03%2Fvcge%23imigrantes .
