[glue-wg] New Endpoint and Service types

[Florido Paganelli]

Hi Paul,

After reading all the discussion with Stephen, I am convinced of one thing:

This is the only correct approach, despite what OGSA definitions are. If
Capabilities are open enumerations, we're free to set another route, and
create specific ones for protocol.

Every other solution is cumbersome and complex in my opinion-- and the
amount of email exchanges tells.

And it also solves the problem you mentioned later:

the above means that publishing http (or any other value in the
Protocol) is the minimum common protocol that tells nothing about the
features of the endpoint. Whatever we put there will always be half the
truth.

So if we think is wise to keep the minimum common protocol in the
protocol attribute, we must have other standard means of exposing features.

Your proposed approach using profile I don't like, because it mainly
applies to web services IMHO.

I vote for creating better Capabilities.

Cheers,
Florido
