WSO2 has an open source SOA registry and repository in the works, which is good news. The commercial products are generally overpriced in my opinion. You can find the project
here.
Paul Fremantle, Co-Founder and VP of Technical Sales at WSO2, lists the motivation and features of the registry on his blog. Here is an excerpt from his
blog post:
So fundamentally the approach we have taken is to build a registry/repository based on REST concepts. And as we looked at the REST space, we kept noticing how close the Atom Publishing Protocol (APP) is to our needs, so we've made that the public remote API to access the repository. Of course, if you are just browsing the registry, you only need a browser - APP is mainly there to support updating resources.
If you want to join in, you can subscribe to registry-dev, or you can download the code, have a play around and submit some JIRAs. Join the fun!
Note also that CentraSite has a community version (free) SOA registry that I have
written about.
