Instructions for doing a doc review

See DocReviewProcess for more instructions

  1. Does the documentation define the Users of your Package, i.e. for the expected usages of your Stack, which APIs will users engage with?
  2. Are all of these APIs documented?
  3. Do relevant usages have associated tutorials? (you can ignore this if a Stack-level tutorial covers the relevant usage), and are the indexed in the right places?
  4. If there are hardware dependencies of the Package, are these documented?
  5. Is it clear to an outside user what the roadmap is for the Package?
  6. Is it clear to an outside user what the stability is for the Package?
  7. Are concepts introduced by the Package well illustrated?
  8. Is the research related to the Package referenced properly? i.e. can users easily get to relevant papers?
  9. Are any mathematical formulas in the Package not covered by papers properly documented?

For each launch file in a Package

  1. Is it clear how to run that launch file?
  2. Does the launch file start up with no errors when run correctly?
  3. Do the Nodes in that launch file correctly use ROS_ERROR/ROS_WARN/ROS_INFO logging levels?

Concerns / issues

Tully

  • All messages are documented in the msg file.
  • The summary is accurate.
  • Tutorials links to tf package.
  • Troubleshooting links to trac

Jeremy

  • Nit-picky detail. I don't like the "This expresses" usage in the message docs. It is inconsistant across messages. I much prefer the "A representation of _____" phrasing.

    • For example, in Wrench I would rather see: "A representation of force in free space, separated into linear and angular parts."
  • (./) r24763 I would like a pointer from TransformStamped to the the appropriate tf documentation.

  • (./) (ticketed into geometry stack https://code.ros.org/trac/ros-pkg/ticket/3008) On several messages, a pointer to good reference on fixed-axis representation would be nice.

    • A possibility would be a section on the main page for: definitions of terms and conventions. I don't think it has to be fully flushed out yet, but it would serve as a place to start putting that information when they needed it.
  • (./) (added to common_msgs)A short description and links as appropriate to an explanation of ROS messages, the the goal of having message-only packages to serve as a means of allowing nodes to interact without compilation dependenciees would be great, but probably unnecessary.
