This work package compared Sakai/ CHEF with Alternative Frameworks for a VRE. By a ``framework" we really imply a means to deliver the VRE services in an appropriate way to end users and developers. This comparison is restricted to the high-level open source and platform independent frameworks, that is, Sakai, Gridsphere, CHEF/ OGCE, and Bodington. For the purposes of this report, we regard uPortal and Jetspeed as enabling technologies (portal containers) and do not review them here, indeed there are many others which fall into this class. This comparison is an ongoing task and lasted for the duration of the project as much of the technology and functionality is still changing.
