Apologies for jumping in late on this topic.

In the geospatial community, "process" is the term most often associated 
with the set of processes (as captured in an overall workflow) applied to a 
specific set of content, such as a satellite image or full motion video 
feature extraction. This concept is captured in ISO 19115: Metadata as 
ProcessStep. The only reason I bring this issue to the group is that ISO 
19115 is the mandatory geospatial metadata model (and related encoding) as 
specified in the INSPIRE implementing rules in Europe as well as in a number 
of Asian countries. Further, all of the OGC Sensor Standards use the concept 
of "Process" as part of those specifications.

Obviously, names/concepts can be mapped from one to the other.

Thanks

Carl
