Hey, I just created a PR https://github.com/hawkular/hawkular-inventory/pull/10 with my idea about how the "true" inventory API could look like + an implementation of that idea on top of Tinkerpop Blueprints graph API. A lot of stuff is missing there but they should hopefully fit in the basic picture outlined in the PR. I kindly ask for your comments and ideas about it. It does not exactly follow the ideas we were talking about in the various design talks but I think it captures the essence of them. Thanks, Lukas
