Use case from SUIT:
SUIT needs to provide a capability for users to browse all the possible metadata so users can decide what they want to explore further. The following API is needed to support this.
- SUIT needs to get all the databases (science, EFDs) to allow users to select and browse what is available:
- DB name,
- type (does it have engineering data, catalogs, image metadata, multiepoch photometry table to obtain light curves?)
- description,
- possible link to the formal document about this DB
- we also need to know the name of multiepoch photometry table, which contains the single-exposure measurements for every deep detection,
for example 'Science_Ccd_Exposure' for SDSS, 'allwise_p3as_mep' for WISE. This is assuming there is one such table per database/schema.
- For each DB, SUIT needs to get a list of tables in the DB:
- Table name,
- type (image metadata, catalog - source/forced source, EFD-related),
- description,
- possible link to the formal document about this table
- when a table has object id, what is the name of multi-epoch table to get light curve queries for this object
- For each table, SUIT needs to get the following information for each column of the table:
- UID (to identify columns that hold ra and dec, filter band, object id, image corners)
- UType (extra info like the 4 corners of an image, ...),
- name,
- description,
- unit,
- data type
- relationship with columns in other table ( objectID in object table to objectID in source table)
unless this relationship can be determined using UCDs
Since all users will login to the system, the permission of access level will be controlled by User Authorization system.
Action items
- Unknown User (xiuqin), Tatiana Goldina provide a use case in SUIT to for metaServ, with specific example if possible.
- Brian Van Klaveren post the sites that implemented RegTAP for others to explore
- Brian Van Klaveren research on the grouping of columns to express 4 corners of an image
