IVOA Data Model Working Group

Introduction

The role of the Data Modeling group is to provide a framework for the description of metadata attached to observed or simulated data.
The activity of the Data Model WG activity focuses on logical relationships between these metadata, examines how an astronomer wants to retrieve, process and interpret astronomical data, and provides an architecture to handle them. What is defined in this WG can then be re-used in the protocols defined by the DAL WG or in VO aware applications .

Participation

Membership of this working group is informal as people and projects come and go. To join see our page on How to participate
