Standards & Interoperability

• IVOA ObsCore: discovery metadata model for observations

• TAP/ADQL: query protocol and language for VO services

• DataLink 1.1: associated resources and service descriptors (e.g. #this, #preview, #calibration)

• PyVO: Python client to access VO services

The app uses these standards to query upstream archives and expose downloadable products via DataLink when available.
