Alfresco - The Open Source Alternative for Enterprise Content Management

Alfresco is the leading open source alternative for enterprise content management. It couples the innovation of open source with the stability of a true enterprise-class platform. The open source model allows Alfresco to use best-of-breed open source technologies and contributions from the open source community to get higher quality software produced more quickly at much lower cost.

Our goal is to not only provide an open source offering but to surpass commercial offerings such as Documentum or Microsoft® SharePoint® in terms of features, functionality and benefits to the user community.

Whoa. Founded by one of the guys who started up Documentum. Some big guns backing him and his team up on the money side of things.

This is definitely a product to watch.
