status of OWL amidst other standards

[adasal <adam.saltiel@gmail.com>]

Does anyone have thoughts about the following?



This example below XACML, but it *is* just an example.




I am interested in the relationship between xml -> rdf -> owl



I think this can be divided into two concerns from my point of view but
I will just mention the first, that of the position of OWL in the
market.


This concerns the status of owl amidst all the competing xmls.




An example would be the following:-




ucml have created a framework demo by Harry Chin called COBRA which is
a context aware ontology broker. It allows a mobile client to hold an
owl ontology that includes a permissions profile and a server broker to
reason that the permisions allow certain types of data to be shared.
For instance, suppose I request permision to enter a room in a certain
building, I just request by room. The broker does two things. It
reasons that the room resides in a particular building and, looking at
my profile, it finds I do not have permision for the room, but I do for
the building (which at least will get me to the front desk!)




So that is what it return to me. Introducing time makes this more
interesting, since I may gain permision to that room only on a certain
date, this is returned.




But I have a colleague who, intreaguingly, has told me that he worked
on the first implementation of an XACML server. I don't know enough to
doubt this, that is whether XACML would cover the same ground, but he tells me this is what XACML does.


There must be many other examples. Thoughts anyone?
