[Hawkular-dev] Questions about Inventory in agent

Hi, all. This is Austin. I've been trying to understand how the inventory in agent works. As far as I understand, an inventory is a graph, and the agent sends the graph to the hawkular server with some kind of format. Such that the hawkular server can answer queries with the data that the agent sends. I have a few of questions: 1. What are the various protocols for(dmr, jmx, platform)? 2. And there's Resource and ResourceType, each of them holds a graph, what's the relation between them? Are they isomorphic and each node of ResouceType annotates the corresponding Resource node? Thanks!
