+    Formerly known as the API-WG, the API SIG scope is to improve the developer
+    experience of API users by converging the OpenStack API to a consistent and
+    pragmatic RESTful design. The working group creates guidelines that all
+    OpenStack projects should follow for new development, and promotes
+    convergence of new APIs and future versions of existing APIs.

+    The goal of the FEMDC SIG (formerly Fog/Edge/Massively Distributed Clouds
+    Working Group) is to debate and investigate how OpenStack can address
+    Fog/Edge Computing use-cases (i.e. the supervision and use of a large
+    number of remote data centers through a collaborative distributed
+    OpenStack system).

+    The Scientific SIG (formerly Scientific Working Group) is dedicated to
+    representing and advancing the use-cases and needs of research and
+    high-performance computing atop OpenStack. It's also a great forum for
+    cross-institutional collaboration. If you are (or would like to) run
+    OpenStack to support researchers/scientists/academics and/or HPC/HTC,
+    then please join!

+    Coordinate the use and development of several OpenStack projects which
+    can be combined in various ways to manage OpenStack infrastructure in a
+    policy-driven fashion, reacting to failures and other events by
+    automatically healing and optimising services.
