The IDOC: Integrated Data and Operating Center's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It is thus the VO's premier way to access public data holdings. Tables exposed through this endpoint include: epn_core from the eit_syn schema, epn_core from the gaia_dem schema, epn_core from the omega_cubes schema, epn_core from the omega_maps schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.
