Data Model Working Group : November 2024

The very-high-energy gamma-ray astrophysics (above few tens of GeV up to few hundreds of TeV) is showing the emergence of observatories that will provide proposal-driven observations, open data and open science analysis tools. The largest observatory of such type is the Cherenkov Telescope Array Observatory (CTAO) that is currently under construction. In this context of opening of the VHE astrophysics, the FAIRisation of the data and an efficient data dissemination using VO technologies are necessary to allow multi-wavelength and multi-messenger analyses. The presentation will present the status of the data models of the VHE data products, in regard with the current IVOA data models and model drafts

VO-DML 1.1 candidates

The VO-DML tooling has been extended to include robust Java and Python code generation that enables XML and JSON serialization as well as ORM to databases for arbitrary data models (first reported on in the Nov 2021 Interop, with ongoing progress reported subsequently). This work has highlighed some areas where the VO-DML standard should be clarified, as well as some ideas for extensions to the standard. These ideas have mainly been managed as GitHub issues so far, and this talk is an invitation for people to contribute to the VO-DML 1.1 standardization process. The suggestions so far will be summarized as well as the progress on actually updating the standard document.
