The Proposal Data Model is a IVOA data model for making Observation Proposals. It is being created as project within The Opticon RadioNet Pilot (https://www.orp-h2020.eu).
The model is described in more detail here
This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 101004719
The IVOA standard in development is a Working Draft at version 0.6 and a is automatically produced from this repository when changes are made.
The data model is actually developed in VODSL in directory src/main/vodsl, although the definitive representation is of course in VO-DML. An eclipse editor that can act as an IDE for vodsl can be installed by following these instructions
The use cases for the model are tested by writing java test cases against the auto-generated code. It is always useful to add a test for a new observatory to ensure that the model meets its requirements.
Model site documentation (in the docs directory) requires that graphviz and yq are installed - it can be tested with
gradle testSite
You should follow the usual github flow for making actual changes to the model or standard document. It is also possible to contribute suggestions and errata by opening an issue or less formally a discussion.
