VersioningStrategy

Versioning strategy for CIM

• Standard major.minor.trivial numeric scheme, e.g 2.11.13
• Bump major when changing any part of the schema layout, base metadata or constraint & reference structure, currently:
  • Schema layout ontologies/v2/schema (but not adding a new extension package to core/schema)
  • Mandatory components of doc_meta_info
  • Mandatory components of reference
  • Changes to the specification documents.
• Bump minor when adding a new document class or a new extension package
  • Modifying document_types or changing the mandatory components of an existing document class.
  • Adding a completely new extension package (similar to cmip6 and hence modifying `extension_packages')
• Bump trivial when changing any other properties (including adding new classes/enums that are not enumerations).
• Do not bump anything when changing properties in an extension package like cmip6, that ought to be a version change there, and only there.
