I’m currently using Piwigo for a photo gallery of historic photos from science fiction fandom, with a few thousand images in it (and more on our fileserver not yet organized and published to the web gallery). I just discovered Omeka, which in some ways (oriented towards archival collections, and built around standard metadata including Dublin Core), and am trying to quickly understand Omeka enough to know if I should actually consider switching (always work; could be working on importing new images instead).
So one big question in my mind is “what is the smart way to use Omeka on a photo collection”. Should I be creating a separate item for each of thousands of photos? (not by hand for sure!!!). Or should I be creating an item for (say) all photos from one meeting or one panel at an SF convention, with all the photos from one photographer at that meeting as files on that item? Or some other way? Or it depends on things I haven’t told you?
Secondly, these photos are all labeled with date, location, tags/keywords, and such in metadata fields. In my test so far, I do see that information in the file page for an image I imported into Omeka. However, several other messages in this forum, and my tests, tell me that that information is not searchable, which kind of spoils the good impression! Has anybody found a way to fix this?
Finally, if I need to update the copy of an image file that I have published to Omeka, how can I do that? In Piwigo I just run an rsync from my local virtual gallery directory over to the Piwigo server, and everything I’ve updated since the last time gets found and swept over (then I do have to do synchronization on the web end to get that data into the database). Those updates could involve the image itself, or metadata, or both. How would I update photos here?
