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. 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.
