OGSA-WG has been working on Grid information/data modeling. Info/data modeling is very controversial subject and we 
spent more than 3 years and this document is our first tangible (non abstract) outcome of this activities. 

This work is also very important for alliance and collaboration with DMTF. OGF and DMTF have a work register for 
collaboration more than 4 years. But this trailblazing work identified and remedied the practical problems.
