Canonical Versioning (Erl)
How can service contracts within the same service inventory be versioned with minimal impact?
Problem
Service contracts within the same service inventory that are versioned differently will cause numerous interoperability and governance problems.
Solution
Service contract versioning rules and the expression of version information are standardized within a service inventory boundary.
Application
Governance and design standards are required to ensure consistent versioning of service contracts within the inventory boundary.
Impacts
The creation and enforcement of the required versioning standards introduce new governance demands.
Principles
Architecture
Service, Inventory
When services are versioned according to the same overarching strategy, they can retain their original standardization and interoperability and are more easily understood by consumer designers.
