Hello Tobias, A few comments: - When looking at the ontology in Protégé, datatype like integer appear as classes… That is weird. - This is why you have what I believe is a wrong use of 'object properties'. For example, bitrate should be a dataproperty of media resource instantiated by an integer (not a float ;-) - Language is not a class but an object property linking to a SKOS concept or a data property linking to a string -> the same for e.g. compression, format, genre, keyword, rating and targetAudience - Person should also be a subclass of Actor and probably organisation could also appear where person is. - The flattest the better: I would avoid nesting too much things like audio/video, tracks and then audio/video tracks - partOfCollection could be replaced by a more generic isMemberOf - relation would sound better like isRelatedTo and all Dublin Core relation could be subproperties - For the datatype of samplingRate, we often use rationals, which don't exist in RDF -> float? - Some properties are functional - Some properties are inverse, which I believe needs to be completed by proper object properties - Time to think of appropriate inverse properties for more inference I have put a revised version here: http://www.ebu.ch/metadata/ontologies/W3C_MAWG/ma-ont-rev.rdfs.xml To be discussed ☺ Regards, Jean-Pierre From: public-media-annotation-request@w3.org [mailto:public-media-annotation-request@w3.org] On Behalf Of Tobias Bürger Sent: jeudi, 3. juin 2010 08:03 To: johns@postech.ac.kr Cc: public-media-annotation@w3.org Subject: Re: [mawg] [rdfs taskforce] action-249: RDFS version of ma-ont availble Hi John, starting next week is fine - every review is more than welcome!

You can find it here: http://www.salzburgresearch.at/~tbuerger/ma-ont.rdfs Browsable version: http://liris.cnrs.fr/~pchampin/wsgi/t4r/?tu=ontoview.html&r=http%3A//www.w3.org/ns/ma-ont&gu=http%3A//www.salzburgresearch.at/~tbuerger/ma-ont.rdfs I am still looking for a volunteer to provide a review and to suggest changes, extensions, etc. for both RDFS and OWL versions of ma-ont. Thanks.
