Task Status

This page is part of the ongoing SWIM communities of interest discussions. The content is working material. It should not be treated as final as it is still subject to review, comment and change.

This task will work on service categories in support of SWIM-SERV-009 Service categories. It will reflect the more flexible approach that will be adopted.

Published service category schemes

The current published service categories are at: https://reference.swim.aero/information-services/service-categories.html
