Re: [soa-rm] Opacity calumny

[Ken Laskey <klaskey@mitre.org>]

I think there will be a constant give-and-take between providers and 
consumers, between what providers want to show (and their complaints about 
the cost of showing things and maintaining what they are forced to show) 
and what consumers want to see (e.g. product labeling requirements).  Some 
of this, in particular the information shown, the semantics of the 
information and possibly the automated means to evaluate the information, 
will likely (assuming there is widespread SOA adoption) be the subject of 
laws and regulation.

For our work, I think it is enough to note
- information will be exposed through metadata;
- the links to a/c/p and, if applicable, evaluation engines will be part of 
metadata;
- for greatest use, there should be standard ways of describing a/c/p and 
metadata associated with a/c/p so as to facilitate the greatest possible 
automated use.

What is described through a/c/p and what specific metadata is needed are 
business/implementation issues.
