  • Preliminaries

    • [Kat ][1 min] Please remember to fill out your contribution report at the bottom of this document prior to the meeting.

    • [Angelo Cosaro][5 min] Announcement from ADLINK ⇒ Zettascale

    • [Kat][5 min] 2021 Metrics Report
    • [Lange][20 min] License documentation in ROS
      • Notes
        • Alberto – Similar problems for iRobot. Commercial (BlackDuck) tools don’t play well with ROS 2. More problems working from source vs installation. No consistency in license / copyright locations.
        • Ralph will issue a PR.
        • Chris – Propose and update to the REP that defines package.xml
          • How to manage two license files? This needs to be in a REP.
        • Andrei – Are you scanning deps?
          • Ralph: yes, depends on referenced files.
      • Introduction to license and snippet analysis and examples of findings in ROS.
      • Good news: No severe findings found in ROS 2 core packages (w/o tools) by Bosch-internal license and snippet analysis
      • Bad news: Process is very time consuming and error prone because of insufficient license documentation
        • Information by LICENSE file and package.xml is too unspecific
        • Lack of license information in Debian packages
      • Ideas:
        • Introduce machine readable debian/copyright files
        • Use SPDX identifiers in package.xml, etc.
        • Improve tooling, to check consistency and ideally also completeness
  • Recurring business

PickNik’s @Henning_Kayser and @tylerweaver were also in attendance, but I think they forgot to add themselves to the attendee list.

TSC members: I miss you all!
