ADASS posters are displayed all week
The VO Registry is a set of about 30,000 metadata records of astronomical resources. It is queryable using the powerful RegTAP protocol requiring users to write ADQL. A friendlier interface using that protocol has recently been written a part of the pyVO astropy affiliated package. In this poster, we briefly introduce the standards this is implemented against. The new API can be used by astronomers to discover data based on various constraints, ranging from free text to physical concepts and areas in space, time, and spectrum.
