Almost exactly a year after open- sourcing its previously commercial portal product, Sun has decided to make a renewed push with its launch of "OpenPortal." OpenPortal is a new portal community where you can find all the source code to Sun Portal. OpenPortal remains a young project, but the portal package is indeed evolving. According to a Sun blog entry a new CMS/DM infrastructure will be introduced soon, based on the Apache Jackrabbit repository. As readers of the Enterprise Portal Report know, Sun Portal has thusfar included FatWire Spark as its default Web CMS. Perhaps this will change over time as Sun beefs up its own repository and workflow capabilities. This screencast from Sun offers some nice details about how it all works. More interesting for us is its emphasis on developer power -- so common to open source portal projects -- at a time when many commercial competitors (e.g., BEA AquaLogic, Vignette, and Oracle OWS) are pushing business-user configurability. [Update, June 3: Just to clarify: A Sun employee blog, interpreted this posting as complimenting the forthcoming CMS features. New customers should be aware that the planned CMS offering will not only be untested, but also likely offer fewer features than FatWire Spark.]
