The ActingWeb specification is written in the format of an IETF draft. There is currently no activity to get the specification accepted in a working group on a standards track, but this may be a desirable approach at a later point.
In absence of an external standardisation body to prevent fragmentation and derivatives, I license the ActingWeb specification under a Creative Commons Attribution-NoDerivatives 4.0 International License 
The copyright section in the specification itself gives explicit rights to implement and use the specification for both commercial and non-commercial purposes.
Feedback, suggestions, and ideas are very welcome!
