Chapter 5: Conceptual Modeling

Questions

(Ann Clark) Section 5.3 p. 66 mentions ontology for data governance. Can you provide an example of how an ontology can be used to support data governance?

Also Section 5.3 p.71 For maintenance of external ontologies - can you explain why this is important? I assumed I would import a version of an ontology into an ontology editor and select portions to use. If I've customized or only reused certain classes, how important is the external maintenance aspect?

Another Section 5.3 - If I reuse only properties, but not the specific relationships in an existing ontology, say for a machine learning use case, I assume I'd add it as reference metadata, but may not care about the maintenance or updating of the external ontology. Does this assumption hold water?

Ch. 5 overall: Is a directed graph the optimal way to visualize an ontology regardless of use case? Can you think of any use cases that would benefit from a different type of representation or visualization?
