OMEKA as library system

As being one of the few open-source projects applying the full dublin core is was an excellent candidate for a library system.(here in Mexico)

Only wish there was a template that cataloged things alphabetically or gave you similar choices.

Multi language support might not be a bad thing either.

Support for different languages is coming to Omeka; it's tentatively on our roadmap for the 1.5 release (the release after next).

Of course, even in the meantime, you can customize your theme to use any language you want for visitors to the "public" side of the site.
