Statistics plugins

Hi, I was wondering if there was any plugins out there in the wild that would generate some stats from an omeka collection, a few graphs would be nice.

I'd be looking for :

* number of items over time
* number of transcribed items over time (plugin scripto)
* number of items per contributor

Or maybe this should be done on the exposed OAI-PMH repo ?

I'm not personally aware of any plugins that do this, but the necessary data on dates and user mappings to items is stored in the database, so it's certainly doable.

I don't think the OAI-PMH repository would expose enough information to do all of what you're thinking of; in particular, it wouldn't expose which users are responsible for which items (unless you were embedding that information in a Dublin Core field manually).
