ZNG - what is the long-range objective?

To ZIG-list

It is unclear to me what is the long-range objective of the actual
ZNG-proposal.

I can see two very different:

A) A light weight protocol for search-and-retrieval for end-users in
databases with no overlap to the Z39.50 system-to-system protocol.

B) A protocol with focus on search-and-retrieval for end-user, but with
extensions to carry library-to-library data exchange.

The name ZNG - Z39.50 next generation - says B, men the text in the proposal
say A.

If A - why not co-operation with the OpenURL project? Some of the practical
use of OpenURL are search-and-retrieval and not only linking.

reason was holidays.
