A description of work over the last 5 years in a number of communities who wish to establish standards for communication of processes, workflow information, plans and activity descriptions. This will include work on KRSL, PIF, NIST PSL, and SPAR. The talk will also mention Edinburgh work on a simple underlying abstraction for plan/activity/process ontologies based on representing activity as "constraints on behaviour" - called. This is compatible with the emerging standards. It is proposed as an approach that could be widely used in other Edinburgh work.
