common_interfaces

A set of packages which contain common interface files (.msg and .srv).

Purpose

Isolating the messages to communicate between stacks in a shared dependency allows nodes in dependent stacks to communicate without requiring dependencies upon each other. This repository has been designed to contain the most common messages used between multiple packages to provide a shared dependency which will eliminate a problematic circular dependency.

Contributing new messages and or packages

To be accepted into common_interfaces a package needs to have been API reviewed and be in active use in a non trivial portion of the ROS ecosystem. It’s really supposed to represent messages which are commonly used.

On the way to becoming a member of common_interfaces please release a message-only package and make it available to the community. Once it has matured, been reviewed, tested, and possibly iterated upon by early adopters, then it can be promoted to be a member of the common_interfaces metapackage.
