RDFa for notation tags

[cmueller]

I am enclosing the first draft (and now outdated) representation of the final output of JOMDoc in an rendered OMDoc and XHTML document. We agreed that JOMDoc generates ec-attributes instead of tags (so the tags are outdated). So I assume the below RDFa representation is out-of-date as we only make use of ec now?

OMDoc:

<theory>
 <tag type="notation" 
      xref="ntn123#rend456" object="obj333"/>
 <tag type="notation" 
      xref="ntn123#rend789" object="obj333"/>
 <m:semantics>
   ... 
   <om:OMOBJ xml:id="obj333"> 
   ... 
 </m:semantics>
</theory>

XHTML+RDFa

<div about="obj333" xmlns:o="http://omdoc.org/ns">
 <span rel="o:tag" href="ntn123#rend456" />
 <span rel="o:tag" href="ntn123#rend789" />
 <m:semantics> 
  ... 
  <om:OMOBJ xml:id="obj333"> 
  ... 
 </m:semantics>
</div>

Yes, I think we can drop RDFa here, as it is just not precise enough. An RDF semantics of our @ec notation tags would then, if needed, have to be established by applying an XML->RDF extraction to the document afterwards, e.g. with Krextor. For the semantics that we are interested in and that our applications should support, I think we can use RDF(a) exactly there, where we think it makes sense. Theoretically, one could even drop math content markup and represent complete mathematical formulas in RDF, but that would look quite messy and wouldn't have much value.

Okay, I just removed this part. Thank you.
