Hi Luc,
Comments on your example are interleaved

However, take an activity run by my email client. I would argue that my email
client executable is a specification of an activity and is also a plan.
In this specific case, what's the difference between a Plan and a (Software) Agent?

The code for the email client is a specification vs. email client process corresponding to the distinction between a program (in memory or on disk etc.) and a process (being actively executed).

So a plan would be "check inbox", "read email",  "write email", "check calendar", "check rss feed", etc?

Yes, also update smart folders, show todos ...

But all this is encoded in the programme executable.

A program can have multiple processes, similar to the blueprint of a welding robot, reconnaissance drone and actual robots, drones etc.

The same question also applies to a workflow script, controlling an activity.  Is it an agent
or a plan?

Workflow script is a "plan" or "recipe" or "specification" etc. and not an agent.

Would the workflow engine would be the agent?

For a techie, maybe. But the the workflow script
is an input. So not a plan.

The other issue is that the workflow script can  be seen as an entity. But I understood the plan to be outside dm.

+1 for replacing Recipe.

Plan is a nice alternative - should we make it Activity/Process Plan (corresponds to the Activity/Process Execution)?

PROV-ISSUE-147 (Replace recipe): Change the name if "Recipe" [Data Model]


Raised by: James McCusker
On product: Data Model

We chose Recipe to be explicitly clear about the use of a method or plan to guide a ProcessExecution. We should find a broader term that isn't as tied to the cake example. This is what I recommend. We start with the term "Recipe" and replace it with ever more general terms that are unambiguous. We then accept the broadest possible term that cannot be confused with an occurrent.

My first cut is "Plan". It's short, simple, and unambiguous. I think it's sufficiently general to cover the definition of "Recipe" without being confused with "Process".
