Omeka S

As many of you know, we at the Roy Rosenzweig Center for History and New Media have been busy working on the next generation of Omeka, Omeka S.

Omeka S is different from Omeka Classic (aka, the 2.x series) in several respects, both in conception and in technology stack.

The two primary conceptual differences are that 1) it aims to be ‘multisite’, fitting the needs of institutions that need to deploy many Omeka sites from one installation, and 2) it aims to have better interoperability with other systems, such as Fedora, DSpace, and Linked Open Data.

More details about the evolving shape of Omeka S can be found on the "What to expect in Omeka S" page and in the README file.

End User Information

The End User Documentation has its own section on the Omeka S site.
