[Donal Lafferty] Let me bring the conversation back to the subject line...
WRT to ServerResource implementation, I'd suggested using a RESTful API to hide ServerComponent and ServerResource implementations from each other [1] This left the ServerResource open for implementation in any 'native' language. In contrast, the ServerComponent conformed to Management Server (Java/Spring/whatever our ORM is/etc), and it is meant to be 'generic' to simplify reuse. I reason that the difficulty device access for test and build, and not language choice. Integration testing requires device access, and some tools will only run on a particular platform, e.g. libvirt, MSFT compiler. The language choice is secondary to this problem. WRT to licensing, I was looking for bright line rules [2]. E.g. the Master repo only gets donated code. A process for developing rules for tools and frameworks is what I'm looking for.
