Versioning

This page provides information about versioning in the CAC Ontology Family.

Versioning Strategy

CAC Ontology follows Semantic Versioning principles:

• Major version (X.0.0): Breaking changes or major architectural updates
• Minor version (0.X.0): New modules, features, or significant additions
• Patch version (0.0.X): Bug fixes, corrections, and minor updates

Current Version

The current version of CAC Ontology includes:

• 30+ ontology modules
• 20+ SHACL validation modules
• Full gUFO integration
• CASE/UCO compatibility

Version History

For detailed version history, see:

• Releases Page - Release information and downloads
• CHANGELOG.md - Detailed changelog in the repository

Module Versioning

Individual modules within the CAC Ontology Family may have their own version numbers, but all modules are released together as part of the main ontology family version.

Compatibility

Backward Compatibility

• Minor and patch releases maintain backward compatibility
• Major releases may include breaking changes (documented in release notes)
• Deprecated features are marked and supported for at least one major version

CASE/UCO Compatibility

All versions maintain compatibility with:

• CASE Ontology: Full compatibility with CASE investigation structures
• UCO: Compatible with Unified Cyber Ontology foundational concepts
• gUFO: Integration with Unified Foundational Ontology patterns

Migration Guides

When upgrading between major versions, migration guides will be provided in the release notes and documentation.
