Thanks @prasenjitdan for your interest in porting and maintaining ROS2 packages!
Based on ongoing discussion at ROS2 perception porting status, it looks like the ORK stack may not be a candidate for porting. So this package may not be worth porting for now (or maybe at all), packages needing computer vision messages should consider using the new vision_msgs package instead.
To echo questions asked on separate threads, could you please provide more information on how the packages you and your team want to port are selected? as well as the ROS2 maintenance plan for the ported packages?
Thanks!
