Bob, I wrote a similar representation in WSML-Flight [1] a few years ago
[2], where it was possible to construct an axiom that for a list of
length n there should exist unique values for each of the indices 1-n,
and no others. I doubt that this is possible here (without RIF), is it?

Hello everybody,
in a longer discussion in the Music Ontology mailing list about how to
model a playlist, Samer Abdallah came up with a very good proposal[1]
of modelling a sequence/ordered list (as recently also discussed at
RDFNext Workshop[2]) as semantic graph (in RDF).
So, here we go:
- specification[3] (please also note the anonymous inverse properties)
- concepts and relations in a graphic[4]
- funky playlist example[5,6]
Again, thanks a lot Samer Abdallah for that cool concept.
Comments, suggestions, critics are very welcome.
Cheers,
Bob
PS: its all OWL based ;) however, we could also downgrade the concept
on the basis of rdfs:class, if needed.
