I was wondering about governance aspects in case of SY. Guvnor project tends not to fulfil my requirements, because it is quite "stiff". It would be very convince to base on tool which resources could be edited from within eclipse. Another problem is that when we start to use external artifacts or dependencies then visual editor, which is really great, starts to be partially useless. A good example is configuring the interface for references or services.
Is SY going to integrate with Guvenor or maybe there are plans to make a love with Overlord? Any statements in this area? I really look forward to your answers, because I've easily run into problem of shared resources (like contracts) while evaluating SY.
Yes, we will integrate with Overlord for design-time governance. You can already upload SY applications and resolved shared contract artifacts from the repository today, but we are working to substantially increase the level of integration in the near future. The Overlord team just had a release which includes example projects (including a SY app) and a screencast.
