RDF Collections

Determine if there is a good way of supporting RDF Collections

Description:
Determine if there is a good way of auto-generating rdf:Seq, rdf:List and rdf:Bag triples. An example of when you may need to have bnodes numbered in a particular order if they are children of an typeof="rdf:List" came up as a part of a music application - what happens if you want to automatically order the songs in an album as they are mentioned on the page? There is a mechanism to do this in RDF that autogenerates triples with predicates in the following format:

C rdf:_nnn O

Where C is the container and O is the contained object.

Related notes:

Basically, something like the following:

<ul about="xxx">
<li resource="yyy"/>
</ul>

to generate xxx rdf:type rdf:Bag; rdf:_n yyy. Of course, the li could be a literal.

<ol> would generate an rdf:Seq. Both classes could be overridden with a typeof= attribute.

You could also use <li property="rdf:li"> or <li rel="rdf:li"> to make it more explicit. In this case, the mere fact of using rdf:li should be enough to invoke the rdf:_n expansion, within the subject scope.

By explicitly using rdf:Seq/rdf:Bag and rdf:li the semantics is independent of HTML too.
