A recent Forrester Research report on "Web Content Management and Open Source" highlighted Drupal and Alfresco as the top two projects to watch.
From the CNET news article quoting the Forrester report:
For an open source WCM vendor to be relevant, it must
have a satisfactory product offering, proven enterprise-level
implementations, and a large--and passionate--community of developers
and service providers. Currently, enterprises interested in open source
should keep an eye on two offerings--Alfresco Software and
Drupal--because:
- Both have taken pages from the commercial vendors' playbooks [i.e., enterprise-class support, stability, etc.]....
- Technologists praise the product architectures....
- Both have strong professional communities.
