I would need to pick your brains here, as you might have encountered the same situation to solve: we would like to establish a connection between our digital repository and a real library, that stores many of the documents we have in digital form.
At the moment, the idea is to add to every Item page a link to the corresponding page of the real library’s catalogue, and I was wondering what would it be the best way to proceed: using an existing DC field (like Source, f.i.)? Or maybe add an element and then included it in every single Item Metadata Type? Or even add an extra field to the DC list, so that is available for every single Item, no matter what type it is?
Restrictions are that not all Items have a corresponding one in the library, and that some Items have arrived to the digital repository from different sources, so using the Source field could mess up things a bit.
Please let me know if you have any idea.
