> <div typeof="sioc:Post" about="http://myindex.com#post>

> Otherwise, someone trying to look up the definition for ...#post from the

> not contain that markup.

> Note that "about" in RDFa does not define the topic of the post, but teh

> This is some content related to the product.
>> It also includes a<span typeof="gr:Offering" about="
>> http://myindex.com#offer"><a rel="foaf:page"
>> href="http://somestore.com">special
>> discount offer</a></span> of the product.
>> </span>
>> <span rel="sioc:about" resource="
>> http://www.savingsocrates.com/market/atrapalocl_12#offer"></span>
>> </div>
>>
>>
>>
> At first view, that looks okay.

> @ myindex.com, something like this:
>> (xml name spaces are not shown)
>>
>> <div typeof="gr:Offering" about="#offer">
>> (some gr markup)
>> <a rel="foaf:page" href="http://somestore.com">Buy it here!</a>
>> </div>
>>
>>
>>
> At first view, that looks okay.
>
> @ somestore.com, plain and simple: no RDFa markup, just buy the product.
>>
>>
> I would also put RDFa for the offer into the somestore pages.

> As for authoring (and debugging) such markup, I suggest:
>
> 1. Use the Turtle RDF syntax for modeling the data.
> 2. Convert Turtle to RDF/XML with http://www.rdfabout.com/demo/validator/<
> http://www.rdfabout.com/demo/validator/>
> 3. Convert resulting RDF/XML to RDFa snippet with
> http://www.ebusiness-unibw.org/tools/rdf2rdfa/
>
> For checking whether your markup is correct, use the PyRDFa extractor and
> check the resulting RDF in Turtle syntax:
