Hello. Yes, I am planning to submit the proposal and currently I am working on it. It would be great if you give me information about XWF format. Also are there any more detailed descriptions of XMF format compilers and usage of messaging system? For now I can only explore source code and I will definitely do it lately during development, but now for better general understanding of the system internals and preparation of the proposal such documentation could be very helpful.

You got the requirement very correctly. As you > already figured it out, there are two tasks for this project, first one is a > Airavata XWF format to SWF compiler.

Airavata workflow monitoring > schema is reasonably well defined and the WS Messenger client publish and > subscribe API's have good examples bundled with.
