(thought it better to have a subject line) By way of a response to Etienne's request to hear from other fedora-commons development, and our own announcement:
The NSDL technical network services group (TNS) has released it's own set of tools for repository management based on a fedora-commons back end. At http://ncore.nsdl.org/ you can find information about EduPak (http://ncore.nsdl.org/index.php?menu=services&submenu=services!EduPak) The EduPak bundle (http://sourceforge.net/projects/nsdl-core/) includes a catalog management and search/discovery tool integrated with a fedora-commons-backed repository along with a generalized fedora-commons API for handling resource references and metadata objects. The fedora-commons project has two complete OAI services already, but the MOAI service looks like OAI aggregator heaven. Tim
