Versioning

Versioning shall be based on the principles of semantic versioning. For existing specifications, any new releases will conform to the following style of version numbering.

• MAJOR version when you make incompatible specification changes,
• MINOR version when you make changes in a backward-compatible manner, and
• PATCH version when you make backward-compatible editorial fixes (e.g., updating URLs in references).

Document Metadata

Each document to have the following metadata at the top:

• Version History

2. Each HTML version will reference a PDF version to be kept on Zenodo.
3. Each version will have DOI, to be obtained via Zenodo.
