Profile structure - relationship within containers
I am setting up a profile for the management of a print collection/catalogs.
For a given item (say an impression of a print), I would like to refer to existing catalogues raisonnés (one or more) and it would be useful to store in a container three things : the reference to the catalog, the identification number in the catalog and some comments (print states are sometimes an undecided business...). It would make sense to store the catalog references as occurrences so one would ideally store a relationship in the container. I understand that this can be obtained with the pseudo relationship (an attribute) but not with a true relationship. For th etrue relationship, one would have to get the other two in a container, and leave the relationship as stand alone. Am I getting it right ?
