Hi Pere, A good place to start getting familiar with SCA is the SCA Introduction on the Tuscany website [1] and the OASIS specifications which you can find at [2]. SCA Java Component Implementation spec is of direct interest for you as you can use implementation.java as a starting point for implementation.scala. You can also check out SCA Java Common Annotations and APIs as it will help you better understand SCA.
It will also be helpful if you checkout and run a few samples [3] to see how things are working. You can also checkout the implementation-java-runtime module [4] and debug step by step through the samples and see how the internals of implementation java are working. Another useful link about Tuscany would be the Runtime Overview which you can find at [5]. Regarding the idea of the project, at the moment components written in Scala can be run using implementation.java [6]. As far as I know, there are some incompatibilities between some Scala features that can't be run using the java interpreter. The first goal of the project would be to enable full usage of Scala in component implementations. Apart from that, adding other features based on Scala's nifty features (like the one suggested by Ant) will be a plus. Once you have some ideas, I strongly encourage you to start writing your proposal on our wiki [7]. As I will participate as a student this year, I hope one of the other committers will be able to help with mentoring.
