Dear Raphael, Thanks for this. I was fearing you could add an Xpath to a URI. Resolving URIs is already problematic enough whether you are a #-man or a /-man ;-) Regards, Jean-Pierre From: felix.sasaki@googlemail.com [mailto:felix.sasaki@googlemail.com] On Behalf Of Felix Sasaki Sent: mardi, 24. novembre 2009 04:12 To: Raphaël Troncy Cc: Evain, Jean-Pierre; Pierre-Antoine; public-media-annotation@w3.org Subject: Re: about representing persons (and other things) in our ontology 2009/11/24 Raphaël Troncy <Raphael.Troncy@cwi.nl<mailto:Raphael.Troncy@cwi.nl>> Dear Jean-Pierre, Good summary of the situation but if we consider the current scope of MAWG which is to map between different metadata metadata representations, and as I tried to explain during the call. I agree, good summary from Pierre Antoine. I cannot see how a URI/URL will point to e.g. a complex(type) description within an instance based on a structured schema like tva or mpeg7 personTypes or organisationTypes. These instances might as a whole be seen a linked data via the uri/url of the file location but not chunks. Or are you proposing to have the Xpath added to the uri/url? Is this feasible? Technically, yes, you can have URI containing an XPATH expression if this was your question. Furthermore, does this really make sense? This question is more interesting, and, indeed, it would not really make sense. Not terribly important, but did you have a look at the XPointer registry http://www.w3.org/2005/04/xpointer-schemes/ and the XPath schemes? From my understanding they are intended for creating URIs which contain XPath expressions, though not deployed really. Best, Felix However, this is not what Pierre Antoine was suggesting as he has clarified himself. I think that what we want to do is to provide simple attributes and if data from complex structures have to be concatenated into something meaningful, then we have to define the method in the API. ... OR, through some declarative mechanisms: e.g. a SWRL/RIF rule, or a SPARQL construct.
