Since, as stated under Constraints, an exhibit shall not have more than one electronic source, then this could be made into an attribute of the Exhibit class rather than an association.

The intent of the Evidence Metamodel is to provide more structured ways of constructing
statements related to evidence. One of the goals is to facilitate normalized representation
of such statements as well as the mapping of such statements to RDF triples. Therefore, a
uniform mechanism was selected, which involves using an explicit association class
technique, where the extra association class directly corresponds to a verb in the evidence
statement. The above suggestion does not satisfy these objectives.
