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

Implementation Requirements for Data Models
The "IVOA Document Standards" standard has a broad outline of the implementation requirements for IVOA standards. These requirements fit best into the higher level standards for applications and protocols than for data models themselves. At the Oct 2017 interop in Trieste, the following implementation requirements for Data Model Standards was agreed upon, which allow the models to be vetted against their requirements and use cases, without needing full science use cases to be implemented.
- VO-DML models must validate against schema
- Serializations which touch each entity of the model. These serializations may be 'fake' (ie: not based on actual data files), and are to be produced by the modeler as unit tests/examples.
- Real world serializations covering use cases, produced by others following the model, in a mutually agreed upon format.
- Software which interprets these serializations and demonstrates proper interpretation of the content.
