Folks, Following a weeks time for comments, I have received very little but valuable feedback. I have clarified the definition of the Infrastructure Level, which several people noted was not as clear as it could be. Further comments welcome. It is not yet frozen. -- Take care: Dr. David Snelling < David . Snelling . UK .

Hi, A couple of questions: o Would be good to clarify whether profiles only clarify existing standards or wtherer they can change them? I would hope only clarify or restrict but do not change. Should this be stated explicitly? o I worry about the statement that profiles need not be consistent with other profiles. This then puts in a requirement for meta profiles to clarify interoperability issues between profiles and you get into an endless loop. Surely once a profile is accepted by the GGF process other profiles should be consistent with their predecessors *unless* they have good reason not to do so. People need to talk to each other to make sure profiles interoperate at some level. Also, one typo on page 2 end of first paragraph "later"->"latter", Mario On Tue, 12 Apr 2005, David Snelling wrote:

This is indeed the case. The Profile Template document outlines this in detail and follows exactly the WS-I formulation of profiles. There are a bunch of other details also outlined here as well.
o I worry about the statement that profiles need not be consistent with other profiles. This then puts in a requirement for meta profiles to clarify interoperability issues between profiles and you get into an endless loop.

This is the fine line we are trying to tread. Clearly, the potential for conflicting profiles is a danger to interoperability. However, in order to foster continued innovation, we have not enforced a notion that all subsequent profiles be consistent with those already published (the best solutions might come later). Therefore, the value of consistent profiles verse the value of a new one etc. will be addressed in the internal OGSA review process and then again in the public comment period. I think we can make it work, but we do see your point and have discussed it at length.
Also, one typo on page 2 end of first paragraph "later"->"latter",
Thanks.
