[quote="wjwwood, post:35, topic:674"] expose through the `rmw` API and how youre going to represent it (e.g. are they entity IDs, GUIDs, something else? [/quote] Excellent, as a rule I believe the only outbound data from the RMW layer should be ROS concepts, hiding any DDS notions such as entity IDS or GUID's. I will post the representation API shortly. [quote="wjwwood, post:35, topic:674"] not necessarily mapped by the user, but instead having one participant per process or something like that [/quote] This is interesting, is there a discussion behind the scenes that I could read about and join in? --- [Visit Topic](https://discourse.ros.org/t/ros-graph-information-tools-implementation-discussion/674/36) or reply to this email to respond.
