I agree changing other ROS features to use keyed topics is a much larger undertaking. The only thing we are specifically looking for is the ability to create a msg file which will cause them to be generated at this point. RTI's implementation looks for the (@)key at the end of the line, so realistically just passing along comments from a msg file to the IDL would make this work. For example, our msg file is below: > string<=512 key #//(@)key > string<=512 value We made an update to basically pass this along so the IDL file now includes the following: > struct Parameter_ > { > > string<512> key_; (@)key > string<512> value_; > > }; // struct Parameter_ This obviously doesn't solve the problems with discovery that @dirk-thomas mentioned, but it allows the global parameter setup @wjwwood mentioned, which is how we are using it. --- [Visit Topic](https://discourse.ros.org/t/keys-in-msg/1942/6) or reply to this email to respond.
