Contribution

It introduces new data models and enhancements specifically designed to support radio astronomy within the IVOA framework.

Findings

Identification of incomplete data models in radio wavelengths

Development of new data models for radio astronomy

Improved integration of radio data sources in the VO

Abstract

Data Models are an essential part of automatic data processing, but even more so when trying to tie together data coming from many different data sources, as is the case for the International Virtual Observatory. In this talk we will review the different data models used in the IVOA, which parts of that Data Modelling work are still incomplete, specially in radio wavelengths, and the work the AMIGA group has done within the IVOA Data Modelling Working Group to overcome those shortcomings both in missing data models and support for Radio Astronomy.
