[ogsa-wg] Data: feedback on metadata

[Mario Antonioletti]

Hi,
   I have a couple of small comments that arose from the
previous telcon.

On slide 8 you have a bunch of existing specs that you could use for
metadata. Some of these, CIM, SQL, XQuery have semantics associated with
them while xsd does not. This then begs the question how important are
semantics in this context and should this be specified in some way or
not? It may be possible that these will grow out of communities but if
communities want to talk to each other then a semantical problem will
ensue. The Ohio folks suggested generating some top level ontologies
that could be specialised by groups. Folks would then be starting off
from a common set of parents. I don't know whether this is in scope
or going out too much to the semantic Grid.

Does anyone have any strong views on this? How important are the
semantics of metadata? Is this something that should be considered
or that we should label as being out of scope?
