Bob, A desired feature that led to the current rdf:List structure is the ability to "close" a list - so some separate sub-graph can't "silently" add properties not in the original. Your pattern might allow this through additon of a "maxSlotIndex" property on "olo:OrderedList" (not suggesting this as a design, just an example). #g -- Bob Ferris wrote: > 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. > > > > [1] > http://groups.google.com/group/music-ontology-specification-group/msg/305a42362a1e4145 > > [2] http://www.w3.org/2009/12/rdf-ws/slides/rdflist.pdf > [3] > http://motools.svn.sourceforge.net/viewvc/motools/orderedlistsonto/trunk/rdf/orderedlistontology.n3 > > [4] > http://motools.svn.sourceforge.net/viewvc/motools/orderedlistsonto/trunk/gfx/olo_-_orderedlist.gif > > [5] > http://motools.svn.sourceforge.net/viewvc/motools/orderedlistsonto/trunk/examples/orderedlist_-_example.n3 > > [6] > http://motools.svn.sourceforge.net/viewvc/motools/orderedlistsonto/trunk/gfx/olo_-_orderedlist_example.gif > >
