We've just started using Omeka at my library and have been adding item information using the CSV Import tool. We have a unique identifier that we map to the Dublin Core field "identifier" on import. However, in the admin view every item says it has "no document identifier." We've deleted and readded groups of items with no change. What can we do to correct this issue?
To clarify: when you look at an item in the admin view, does it actually say "no document identifier" in the identifier field? Or is it empty?
Neither; in the item record the identifier field is populated. It's in the browse items screen.
That 'no document identifier' looks like it might be added by a plugin, but I don't see a likely suspect yet. Could you give us the list of plugins on the System Info page (link is at bottom right of the footer on the admin screens)
Looks like it's coming from the CleanUrl plugin. I'm not too familiar with it, but I suspect that if you leave the prefix empty in the configuration, it will work as expected.
That fixed the problem. Thanks so much!
