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

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.
