[Go-essp-tech] Fwd: Re: [metafor] ESGF Metadata Telco

[Cecelia DeLuca]

  Hi, a few thoughts after the call about who does what:

We identified three distinct joint work areas today:
1. Evolution of the CIM (broader than ESGF since other
projects are using it)
2. Implementation of future metadata capabilities that
conform to ESGF (with one maybe as a partnership between
Curator collaborators and E.U. collaborators, so in a sense
this one is smaller than ESGF)
3. Definition of interfaces as an ESGF activity

I am thinking 3. includes:
- what portion of the CIM ESGF will use (i.e. the scope
of the CIM used but not the structure, which is covered in item 1.)
- what are acceptable exchange formats for ESGF?
- aspects of interactions with other interfaces, like the
search

Do others think those are the right jobs for the 3 group?
(This is a little tough because these are different hats
more than different people.)

The questions I had coming out of the call were
a. is there anything else we need to cover in 3?
b. how do we begin talking about 2?
