Hi all,
fistly I must admit I'm a complete novice when it comes to XSLT 3.0
and streaming (though not XSLT 2.0).
My use case is as follows -- a triplestore returns streaming RDF/XML
(omitting namespaces):
<rdf:RDF>
<rdf:Description rdf:about="http://dbpedia.org/resource/Copenhagen">
<dct:title>Copenhagen</dct:title>
</rdf:Description>
...
<rdf:Description rdf:about="http://dbpedia.org/resource/Copenhagen">
<dbo:country rdf:resource="http://dbpedia.org/resource/Denmark"/>
</rdf:Description>
...
</rdf:RDF>
Since it's streaming, every resource description only contains one
property. It's not convenient, so during the first pass I group the
descriptions by subject using [1]:
<rdf:RDF>
<rdf:Description rdf:about="http://dbpedia.org/resource/Copenhagen">
<dct:title>Copenhagen</dct:title>
<dbo:country rdf:resource="http://dbpedia.org/resource/Denmark"/>
</rdf:Description>
...
</rdf:RDF>
Then as the second pass I do the main transformation to XHTML, which
could produce something like using [2][3]
<fieldset>
<label>Title</title>
<input type="text" value="Copenhagen"/>
<label>Country</title>
<input type="text" value="http://dbpedia.org/resource/Denmark"/>
...
</fieldset>
where fieldsets represent resources, and labels/inputs represent
properties/values.
Now my question is, how do I even begin analyzing the streamability of
this approach in XSLT 3.0? I guess my main concern is that such
grouping would not be streamable, but maybe there are other solutions?
Thanks.
Martynas
