roadmap

[Tony Linde]

We need to develop a roadmap of what we intend to do. I see the two key
goals for us to achieve as being:

 A. Create RM v1.1 (incorporating registry schema)

 B. Create Registry Interface (RI) spec v1.0 (incorporating harvesting and
query interface)

I tried a schedule which had these complete by 31-Mar-05 but working
backwards from this date made the intervening activities too tight
(especially considering how long it has taken us to get where we are now and
given that we should allow 4-6 months for testing new versions of
standards). So I then simply worked forward from now, allowing us time for
two more trial developments of the registry schema and one of the combined
RM v1.1 and RI v1.0. This pushed the delivery of the above out to end of
2005.


I would therefore propose the following activities as our roadmap:

2004
====
 1. Publish RM V1.0 to REC status
     31-Mar-2004

 2. Agree modified Resource Metadata Schema (RMS) draft v0.91
     30-May-2004

 3. Agree modified Registry Harvesting draft (RH) v0.2
     30-May-2004

 4. Demonstrate viability of RMS v0.91 and RH v0.2 between projects
     1-Jun-2004 to 30-Sep-2004

 5. Create draft Registry Interface spec (RI) v0.1 (incl harvesting & query)
     30-Nov-2004

 6. Agree draft RMS v0.92
     30-Nov-2004

2005
====
 7. Demonstrate viability of RMS v0.92 and RI v0.1
     1-Dec-2004 to 31-Mar-2005

 8. Develop draft RM v1.1 (incorporating schema)
     31-May-2005

 9. Agree modified RI v0.2
     31-May-2005

10. Demonstrate RM v1.1 and RI v0.2
     1-Jun-2005 to 30-Sep-2005

11. Publish RM v1.1 to PR/REC
     31-Dec-2005

12. Publish RI v1.0 to PR/REC
     31-Dec-2005

I know that this seems like a long time but the fact is that standards which
are widely agreed and which have been proved to work do take many years to
develop.

The key to keeping this effort moving forwards is that we continue to
develop working versions of the registry schema and the harvesting
interface. This will allow us to prove that these standards work and to find
the problem areas.

Feel free to publish an alternative timetable if you think we can deliver
the standards in less time than I've indicated. And I look forward to other
comments as well.

Cheers,
Tony.
