Protege currently supports adding default annotations (e.g., author, date) when new entities are created. However, it does not automatically update ontology-level metadata (e.g., dcterms:modified) when the ontology is saved.
For tools like Widoco, which rely on accurate metadata annotations in the ontology header, this requires manual updates, or writing a script.
Request: Add an option (in Preferences) to automatically update dcterms:modified with the current date whenever the ontology is saved. Optionally allow customizing the annotation property (e.g., owl:versionInfo, prov:wasGeneratedAtTime, etc.).
