How to contribute

The schema file is maintained using an XML editor like Altova XMLSpy.

1. Installation: Simply download the schema files from the repository or clone it using git.
2. Create an Issue for the proposed schema change. Follow the recipe on the Wiki on how to register an issue.
3. Then create a branch from the issue, check out the branch and implement the proposed changes.
4. When the implementation is completed, create a pull request.
5. The pull request will have to be approved by the OCXStandard maintainer before it can be included in the working draft.

Schema versioning

The UnitsML schema is following the Python PEP 440 versioning recommendations.

Following PEP 440, the canonical public version identifiers MUST comply with the following scheme:

[N!]N(.N)*[{a|b|rc}N][.postN][.devN] see the PEP 440 for a detailed explanation.

tbump versioning tool

The Python tbump tool is used to automate and bump schema versions. tbump also provides the possibility for pre- and post-commit actions. The project config file pyproject.toml contains the tbump settings.

Usage

Assume that the current schema version is 0.9.18. To bump the schema version to a new version 1.0.0 version, the following command can be issued:

> tbump 1.0.0

Naive databinding

A set of Python dataclasses are autogenerated after each version release, see databindings
