Greetings – I’m still learning a great deal about Omeka, so I do apologize in advance if this question is either obvious or covered elsewhere.
What I’m currently struggling with is whether it’s possible for a resource to have more than one class, as in real life, a resource may indeed possess multiple qualities expressed as classes in an ontology in addition to the properties and subclasses contained therein. For example, after importing the BibFrame Ontology, both Agent and Role would be very useful to access for the item set at hand (rare books), but they are both in the Class drop-down, and one must pick one or the other, to the exclusion of other classes as well. Many thanks in advance for any assistance.
