A Vector Extension for ADQL

Markus Demleitner
Universität Heidelberg

Several relational databases now have powerful facilities for processing arrays. When these facilities are made available via – preferably standards-based – network services, they open up attractive possibilities for server-side analysis of large collections of vector-like data. The Virtual Observatory has the Table Access Protocol TAP to transmit queries in the common query language ADQL (and to retrieve metadata and query results). In this talk, we will present an extension to ADQL to provide a useful set of operations on vectors. We will show how this extension can already be used, using mainly the Gaia XP spectra on the server side and TOPCAT as a client.
