International Virtual Observatory Alliance
This note specifies how to define the roles individual VOTable fields have
within the STC data model and the coordinate systems they are expressed in
using VOTable GROUP, PARAM, and FIELDref elements.
It is hoped that the basic mechanisms proposed here can be applied to data
models other than STC as well.
This is an IVOA Note expressing suggestions from and opinions of the authors.
It is intended to share best practices, possible approaches, or other perspectives on interoperability with the Virtual Observatory. It should not be referenced or otherwise interpreted as a standard specification.
