Hi Everyone!
I am working with a relatively new installation of Omeka. We have successfully harvested data into Omeka using the OAI plug-in. Now I am working with the data in Omeka and having some problems. I do not think it is an OAI issue, but rather a problem with the search functions in Omeka.
I have 5121 items in Omeka. For now they are all from one repository, which should be listed in the "source" element. When I search in the Omeka administrative interface I get 4112 items with the proper source. I get the same number if I search "is not empty" in source. However, if I search source "is empty" I get no items. About 1,000 items are therefore missing their sources, but I cannot produce a list of them.
I think this is a problem with the metadata we harvested. However, unless I can figure out what items are missing the source element, I can't go back to the original repository and fix the items. I did find one item (by random luck) that seems to be among the missing records. It has nothing in the source element, on the public, administrative, or editor interfaces. Yet a "is empty" search does not return it. If it has an invisible white space character, it should show up under the "is not empty" search, right?
Any advice, or description of similar problems would be useful.
I am running:
Omeka version 1.3.1
Exhibit Builder 1.0
OAI Harvester 1.0
Simple Pages 1.0
and Simple Contact Form .3
Other plug-in are inactive
Thanks
