The Roy Rosenzweig Center for History and New Media, George Mason University has released "Happy Beta Release Day, Omeka S!!."
Here's an excerpt:
Omeka S is the next-generation, open source web-publishing platform that is fully integrated into the scholarly communications ecosystem and designed to serve the needs of medium to large institutional users who wish to launch, monitor, and upgrade many sites from a single installation.
Though Omeka S is a completely new software package, it shares the same goals and principles of Omeka Classic that users have come to love: a commitment to cost-effective deployment and design, an intuitive user interface, open access to data and resources, and interoperability through standardized data.
Created with funding from The Andrew W. Mellon Foundation and the Institute of Museum and Library Services, Omeka S is engineered to ease the burdens of administrators who want to make it possible for their end-user communities to easily build their own sites that showcase digital cultural heritage materials.
