Hi Everyone,
Please take a look at the proposed REP 144 for final voting.
https://github.com/ros-infrastructure/rep/pull/96
The body of the rep is available at REP 144 -- ROS Package Naming (ROS.org) pending a few clarifications in the initial parts of the final review.
This is just formalizing the naming requirements into a REP from what’s already expressed on the wiki page: ROS/Patterns/Conventions - ROS Wiki
And please follow up with a vote on the issue to ratify the REP in the github issue. REP voting guidelines are available at REP 10 -- Voting Guidelines (ROS.org)
