Hi all, I've developed an implementation of OCCI with Elixir language: exocci. Elixir is built on top of erlang platform but is largely inspired by Ruby for the syntax (Jose Valim, founder of Elixir, is a former core developer of Ruby). One of Elixir strength is its capacity to write DSL... which is particularly useful for OCCI. exocci then defines a DSL for defining categories. Examples can be found in tests: https://github.com/erocci/exocci/tree/master/test So far, I've developed: * implementation of core concepts with associated DSL for defining kind, mixin, attributes, actions. * a store for creating/deleting/... entities with filtering DSL Basically, less more features than erocci but far more easy way to use it, I hope :) Any feedback welcome !
