Table information for ''


Table Description: A table of TAP services harvested from the registry (and some spoon-fed).

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

The global TAP schema collects information on tables and columns from known TAP servers. This facilitates locating queriable data by physics (via UCD) or keywords (via description).

Note that this shouldn't really be necessary as all information present here should be exposed through Registry records. However, in reality data providers currently are much more liable to give column metadata in their tap_schema than in their Registry records. Hence, for the time being, we maintain this service by harvesting tap_schemas about monthly.

For a list of all services and tables belonging to this table's resource, see Information on resource 'GloTS, the Global TAP Schema'
