***************************************************************************
07-Jan-97 2MASS DBWG Meeting Minutes

ATTENDED: Nian-Ming Chiu, Roc Cutri, Tracy Evans, John Good, Carol Lonsdale, 
          Joe Mazz

HIGHLIGHTS:

Nian:      o Initial Informix server config is ready for 2MASS testing.
             See his email.
           o We initially have one big data partition to play with.

Roc:       o We need to integrate the 'master scan database'
             (subset of 'scan log' for scheduling observations)
             into the system.

Tracy:     o Working on SIS's for DBMAN & WSDB field defs.

Joe, John: o Suggested name for the system now on the draft Web pages is
             "IPAC Science Archive Information System" = ISAIS
             (this is an info. system based on the IPAC science archive).
             "IPAC Science ARChive" (ISARC) was suggested previously. 
             (Joe & John say: "But this is not just an archive.
             It is a software information system to do science with it.)
             Other name suggestions or comments?
           o ISAIS Web page (and directory) layout for draft design 
             docs and the prototype user system were revised. 
             Point Netscape to crystal:8080/ 
             Suggestions for improvements and additions are always welcome.
           o 2MASS Web accessible directly at crystal:8080/2mass/
           o Work on infrastructure & user system design docs.

Tracy:     o Work on DBMAN SIS's.   

Carol:     o Data disk partitioning and system design should be done
             considering that spatial cuts, typically in |glat|,
             will be common to the majority of queries.

All:       o We need to learn in detail how missing data (NULL) and 
             scaled ints are treated by Informix/Illustra.
           o Schedule 16 Jan meeting to review 2MASS+IRAS
             science requirements for ISAIS (or ISARC?) with 
             to open channels for requirements input for other
             IPAC missions.

PRIORITY ACTION ITEMS FOR NEXT WEEK
(Ongoing actions omitted here. See task schedule on Web.)

Nian:      o (Re)configure Informix data/work space for non-2MASS db's.
           o Work with Tracy and Joe to load IRAS FSC and 2MASS SIM 
             into Informix.

Tracy:     o Load 2MASS SIM into Informix (w/ Nian & Joe)
           o Document DBMAN (3 SIS's); define additional fields, etc.
           o Help Joe make Web index for 2MASS SIS's, especially those
             requirded for ISAIS.

John:      o Schedule Informix/Illustra (Universal Server?) class for us.
           o Ping Informix about more copies of the docs for us.
           o Help Tracy complete draft column definitions.
           o Read docs to learn how missing data (NULL) and 
             scaled ints are treated in detail by Informix/Illustra.

Carol:     o Sign off on Joe's revisions to the Requirements doc.
           o Discuss hardware budget with Tom & Roc.

Joe:       o Load IRAS FSC into Informix (w/ Nian & Tracy)
           o Evaluate SDSS interface.
           o Complete Xcatscan+IRAS sections and revisions of 
             Requirements doc in preparation for 16-Jan meeting.
           o Hook SIS's to internal 2MASS Web (w/ Tracy & Roc).
