Abstract and line 46: 'Global' -> 'Open' and GGF -> OGF

Abstract & elsewhere (163, 165): You use 'interoperability' alot but there is only one implementation and only one model. Is this the right word?

141: deprecated - these terms might mean more to readers of this document from other communities. I'm not sure deprecated is the right word. Perphaps - 'these will be used in preference throughout this document'?
 
255: 'What are the same rules' ? Explicit delclaration of what you mean would be useful here.

Figure 4 did not print well in bloac & white on my printer. Additional lines in top box.

315 & 329: Workgroup -> Working Group

400: What do you mean by 'Grid Recommendation' Check with Greg Newby on the current phrasing but I believe this should 
be 'Full Recommentdation'

Generally an informative useful document. If this is designed to be a 'self help starter guide' having some text as to 
what you should do if you want to develop an infomration model, e.g. who to contact - the doument editor, OGSA-WG, OGSA 
RM design team, etc. Will they provide help etc.?
