  Tables exposed through this endpoint include: main from the lbcs schema, main, mom0 from the sauron schema, img_main, main from the lofartier1 schema, img_main, main from the tgssadr schema, main, msssvf_img_main from the mvf schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, hetdex_images, img_main from the hetdex schema, img_main from the msss schema, obscore from the ivoa schema, beam_cubes, calibrated_visibilities, continuum_images, flux_cal_visibilities, pol_cal_visibilities, pol_cubes, raw_visibilities, spectral_cubes from the apertif_dr1 schema.

Tables defined within this resource descriptor

• tap_schema.columns – queriable through TAP and ADQL

  Columns in tables available for ADQL querying.

• tap_schema.groups – queriable through TAP and ADQL

  Columns that are part of groups within tables available for ADQL querying.

• tap_schema.key_columns – queriable through TAP and ADQL

  Columns participating in foreign key relationships between tables available for ADQL querying.

• tap_schema.keys – queriable through TAP and ADQL

  Foreign key relationships between tables available for ADQL querying.

• tap_schema.schemas – queriable through TAP and ADQL

  Schemas containing tables available for ADQL querying.

• tap_schema.supportedmodels

  Standard data models supported by this service.

  This is a non-standard tap_schema table used by DaCHS in the creation of registry records. It is manipulated through gavo imp on tables with supportsModel and supportsModelURI properties.

• tap_schema.tables – queriable through TAP and ADQL

  Tables available for ADQL querying.

• tap_schema.tapjobs

  A non-standard (and not tap-accessible) table used for managing asynchronous TAP jobs. It is manipulated through TAP job creation and destruction internally. Under very special circumstances, operators can use the gavo admin cleantap command to purge jobs from this table.

  Note that such jobs have corresponding directories in $STATEDIR/uwsjobs, which will be orphaned if this table is manipulated through SQL.
