Breaking Changes

(These are changes to ontologies, classes or properties in the preexisting ontology that make the new release non-backward-compatible.)

UCO 2.0.0 will consider the following breaking changes. They are implemented in UCO 1.4.0 as “Warning”-level SHACL violations; in 2.0.0, they will be “Error”-level.

• Warned if target or source on an ObservableRelationship are not Observables (GitHub Issue 573)
• Warned of prior disjointedness declarations in core: and types: (GitHub Issue 586)
• Warned if an AlternateDataStream instance is not also a FileSystemObject (GitHub Issue 590)
• Warned if a observable:Disk instance is not also a observable:StorageMedium (GitHub Issue 612)
• Warned if an OperatingSystem instance is not also a Software (GitHub Issue 632)

Changes

(These are changes to ontologies, classes or properties in the preexisting ontology.)

• Added review mechanisms for key-uniqueness in types:Dictionary (GitHub Issue 602)
  • Added new subclasses of types:Dictionary, types:ProperDictionary and types:ImproperDictionary
  • Added test for key uniqueness of dictionary entries for types:Dictionary, with “Warning”-level SHACL violations raised if repeated keys are found
