Question 1 of 3

1. Question

What is the core modelling commitment that lets CIDOC CRM represent contested and evolving knowledge about an object?

It records every claim as a direct attribute of the object with a confidence score attached
Correct Incorrect Correct answer

It stores each curator's dataset in a separate named graph so disagreements never meet
Correct Incorrect Correct answer

Almost nothing is asserted directly between an object and a value; production, acquisition, identifier assignment and attribution are modelled as events and activities
Correct Incorrect Correct answer

It uses open-world reasoning so contradictory dates do not trigger an inconsistency
Correct Incorrect Correct answer

Question 3 of 3

3. Question

What is the lesson’s stated rule for linking your records to entities in a public graph?

Replace your local identifier with the public one so both systems share a single key
Correct Incorrect Correct answer

Never overwrite your own identifier; keep your identity and add an external match assertion, so changes upstream degrade to a stale mapping rather than a corrupted identity
Correct Incorrect Correct answer

Link only to DBpedia, since Wikidata items are merged and split too frequently to cite
Correct Incorrect Correct answer

Accept a link when the entity labels match exactly, and record no confidence value
Correct Incorrect Correct answer

Correct / 1 Points

Incorrect / 1 Points
