roadmap

[Markus Dolensky]

Hi Tony,

Coming back to the proposed roadmap: Speaking from a content provider point of 
view there is really only a single date that matters. That is the day when 
there is a query adapter* (detailed at EOF message) to a full registry. The 
state of maturity of the underlying Schema is secondary to content providers 
who want to publish their data.

So, the question is:
Which bullets (1-12) in the roadmap need to be done to reach this point?

Again, this is not about harvesting between registries, but utilizing 
registries by applications.

Markus


BTW, thanks Ray et al. for your excellent summary on lessons learned using Schemas.

*)
The server side registry adapter is the piece of software that enables an 
arbitrary archive browser (web form, servlet) to talk to the registry through a 
standard interface. Similar to a target resolver the idea is that a user will 
not query the registry directly, but the archive browser will generate queries 
to a full registry dynamically depending on the context of a user session.

Of course, the assumption is that at least one institution is willing to 
implement the specifications for such a registry and provide it as an 
operational service and not just as a prototype for prove of concept.
