I've released version 0.1 of the Fedora unAPI HTTP Service to Sourceforge.
No major changes since the original prototype, except for the addition of a FedoraPmhResolver. In contrast to the FedoraResolver, the FedoraPmhResolver relies on Fedora's OAI service to describe the available formats for Fedora objects. Depending on the desired use, one may be more suitable than another. The FedoraResolver is more flexible and can support arbitrary formats, but it requires Fedora 3.x. The FedoraPmhResolver should work with any version of Fedora that supports OAI-PMH (although I've only tested it with 3.0).
Similarly, I expect the DSpacePmhResolver should work with any version of DSpace that support OAI-PMH, but I've only tested it against 1.5.1.
