LLD>Yes, that is being accounted for -- within the proposed tabbed dialogs
for actors, directors and workflows, there is a parameters tab.  And within
the proposed actor tabbed dialog, there is a parameter tab and a ports tab.
This is being done so there is one dialog to go to for an actor, workflow or
director where everything about that object can be viewed and/or configured
in one place.  These dialogs were identified as a primary priority by a
group of us that prioritized the UI issues to deal with in the next release.
See: http://kepler-project.org/Wiki.jsp?page=WorkflowDirectorAndActorDialogs

As a related note, there will also be an annotations tab too so users can
easily see how an actor is annotated and users can also view port
annotations from the ports tab.

Subject: Re: [kepler-dev] actors with token rate via parameter


I looked at UpSample and noted that its input port has a fixed
'tokenConsumptionRate' of 1, while its output port has 
'tokenProductionRate' equal to 'factor'. 

Since 'factor' is an (actor) parameter, the ouput production rate can
be changed via factor.

Is this the "recommended" way of dealing with token rates? That is,
often they are fixed, but in special cases they might are mutable, and
if so this is indicated by "elevating" them to actor parameters!?

Some further questions and comments: 
- I haven't followed in detail the usability suggestions made by Laura
for Kepler, but I would guess that showing actor and port parameter in
a (possiblity tabbed) window together (albeit clearly delimited) might
be a good idea for some applications/users.
- Also being able to express parameter constraints (mandatory ones, as
well as "recommended" ones, and even plain English comments) might be
useful.

PS In Ptolemy, I *eventually* found 'upSample', but was missing the
Kepler quick-search function. Conversely, in Kepler, using
quick-search I quickly found that 'upSample' was (probably)
absent. Clearly, one wants the best of both worlds... :-) 
Maybe quick-search and some of the (planned) dynamic actor repository
stuff will make it into Ptolemy later (or if Ptolemy hackers help,
sooner :-)
