[Openflow-dev] Bug, renaming a process

[<jm...@so...>]

When I rename a process, it seems that it takes in account if the process
internals is good or not.

I got this error, and the process folderish object is not renamed:


Zope Error

          Zope has encountered an error while publishing this resource.

          Error Type: AttributeError
          Error Value: begin_end



          Troubleshooting Suggestions

              The URL may be incorrect.
              The parameters passed to this resource may be incorrect.
              A resource that this resource relies on may be encountering
an error.

          For more detailed information about the error, please refer to
the HTML source for this page.

          If the error persists please contact the site maintainer. Thank
you for your patience.

Check the value of the "application" attribute, it has to be the url of 
the application linked to the activity. If the url is not correct it 
generate a broken link.

[Openflow-dev] Which is the latest version?

[Thomas G. <gu...@we...>]

Hi!

I searched the web for the latest version.
On Zope 0.4 seems to be the latest. On Sourceforge, too.
But on downloads.sourceforge.net/openflow is a 1.0.2. 

There the 1.0 Version is twice as big as the 1.0.2

Please tell me where to get the latest version (CVS)?

[Openflow-dev] Bug in todolist.dtml

[Thomas G. <gu...@we...>]

I already filled a bug report. But I send it here again.
Please CC: to me, I am not on the list.

I am using version 0.4

There is a broken link  in the To-Do list of OpenFlow.

I want to follow the link to "unnamed_customerNUMBER" but the URL
is not there.

The problem seems to be in   
<a href="<dtml-var "_['sequence-item']['application']" url_quote>?<dtml-var "_['sequence-item']['parameters']">">

of todolist.dtml

The link goes to:
http://localhost:8080/mywf/myBegin 

myBegin is the name of my Begin action

I changed it manually to:
<a href="mypr/Begin?<dtml-var "_['sequence-item']['parameters']">">
and it seems to work. But up to now I have no deep understanding of
OpenFlow

Why do I need to set the name of the activity?

For the moment is possible to import/export only workflow without tokens=20
and I think we have to work a lot for impletment also token=20
import/export. Every comments and suggestions ar welcome.

Yes, also in mine. Xron works well for me running zope as a user, but not
as root.



In fact, the idea I think is true and must be applied in the real life, is
that a manual activity can be automatized.

For example, I define a process with manual activities, I do manually
while I am developping some tools for doing it automatic. That is very
powerfull, because my process can start working (a kind of "fast
developpment) with a slow load, while I am developping the automatic
product, which I will put in activity to have a faster machine (process).
Suppose that something this automatic product is failing: I can allways
go back to manual (and sleeping less :-)
I am thinking in the workflow of an e-commerce enterprise, a
process is a glue for the software modules: accounting, web, etc...


A difference is: while an employee must do its work, how do I know that an
automatic activity is not "dead" ?? But this is another problem.

No sorry, I was talking about "my" vision, which seems to be the same than
yours. I have not yet tried last version of Openflow (0.4) which has

Yes we are interested in share work and we are also very interested in CMF integration. We aren`t CMF experts but we think is a good product.

Let me know in which direction you want to start the integration and we can build together a development plain.

Every good ideas (and good developers :) ) are well accepted in the 
OpenFlow Project, so if you have suggestions on the structures, the code 
or everything else, let us know and we could work together to build a 
better product.

[Openflow-dev] Idea for automatic activities

[<jm...@so...>]

I think that there could be a kind of automatic activity, marked with a
boolean property "automatic (true/false)"

When a token arrives, pushed by the "moveto" signal or because it has just
been created, it looks fot this property, and if it is true:

a new thread is created, and the url in the field "activity" is open (like
it is done in the Xron product). And then, maybe this activity could be
marked as "pending" (???).

In fact, there is not difference with a normal activity, because the
workflow is still waiting for an external "moveto" signal to do something.


What do you think ??

[Openflow-dev] Task triggering

[<jm...@so...>]

I have been thinking a bit on how to trigger events from openflow.

In fact, openflow is a passive map of the process, and tokens are moved by
tasks.

I am asking myself if it is a virtue or a defect.

The fact is that when you don't execute the tasks, you don't have to
bother about what happens if they fail.

Is a mixt model good ?
In a kind of task (passive task) tokens are moved by the task (calling
activity.moveToken, like it happens in the example) and in other (active
task) the token is moved by an intermediate unix process which launch the
"pending" tasks (the tasks that have activated the "automatic" flag). It
could even be possible to define what to do if the task has failed (two
methods, do_the_task, undo_the_task).


Uhm, is there some plans at this respect ???

Ok, now I see from where it comes from.
But I don't see the relationship between

 http://localhost:8080/test/test/example_workflow/one_end?<parameters>
and
 http://localhost:8080/test/test/one_end

How does this work?

[Openflow-dev] OpenFlow 0.3 questions

[<jm...@so...>]

I have installed OpenFlow 0.3,
some questions:


Q: Why when you watch the url example_workflow/todolist you can see a
determined user the todolist list ?
A: The folder example_workflow is a OpenFlow object, and the todolist
method does this.
(correct?)

Q: In this todolist, I can see the activities, and in each activity I can
see the tokens in this activity (this is VERY nice), with hyperlinks on
the tokens like:
http://localhost:8080/test/test/example_workflow/one_end?token_id=3DAnonymo=
us+User996332330.652
(this is for the activity END of example_one)
Where does "one_end" come from ?
Is it related with my the folder /test/test/one_end ??
When I create my own process, must I create this folders for each activity
?

Q: What are the modes of the activities: "and, And, Xor ??"
A: It is the logic gate.
From=3Dand, means that to start the activity, the token must have
finished all the activities converging to this one.
From=3Dxor, menas that to start the activity, the token must have finished
only one (??) of the activities converging to this one (what happens
if the token finish one activity, and then another ??)
From=3DAND ????

To=3D I don't know what it is for.


Q: Flexibility. Is Openflow flexible ?? Can I change easily "by hand" the
state of a token, move it manualy, because in practice the workflow is
orientative, and sometimes things don't happen the way you think.
A: It seems, because it is zope and than can be changed through zope admin
interface (correct ???)

I fully agree that most applications have a significant workflow component 
and that we have reached a point where this becomes more and more apparent 
and explicit.  It is great that OIO breaks ground here!

In my current way of thinking, I rather see PROforma as an application on 
top of a generic workflow system than the other way around.  <quote>The 
PROforma language structure is based on a simple but versatile clinical 
process model referred to as the "dominio model".</quote> (figures 1 and 2 
in http://www.acl.icnet.uk/PUBLICATIONS/ms364.pdf).  This dominio model 
seems to be the basis for the definition of PROforma's formal 
semantics.  In my reading, this implies that the process model is clearly 
specialized (and thus not general).

Some sections of the paper show workflow processes as "task networks" (also 
called "object-oreinted view".  While this makes the impression of 
generality, I understood that the object view has more to do with making 
the process model accessible to users (through a GUI) than with defining 
the process model.

So the main point is that the dominio process model is highly domain 
specific.


I'm thinking aloud here, comparing PROforma to the general process model of 
the WfMC to try to find other possible differences (please correct where 
necessary):  PROforma's Enqueries and Actions roughly correspond to WfMC's 
Activities;  Plans seem to correspond to Processes;  Decisions are 
comparable to WfMC's Process, and Decisions are loosely related to 
And/Or-Joins/Splits.

One of the major differences I see are in the expressiveness (and level of 
specialization) of Decisions/Joins/Splits.  Obviously, PROforma--being a 
decision support tool--gives much more "meat" to the decision aspects.

Another significant difference of the PROforma and WfMC approaches that I 
sense is that PROforma's process model explicitly includes resource 
(patient data).  WfMC's deals very little with resources and an RFC for a 
resource model seems to be out only now.

This is my reasoning for thinking that it may be possible to implement 
PROforma on a general purpose workflow engine but not the other way around.

>How different are PROforma and OpenFlow in terms of the range of workflow 
>that they can model?

I believe PROforma is specialized and OpenFlow much more 
generic.  Therefore, it seems that it is difficult to apply PROforma 
outside its domain, but possible to specialize OpenFlow for various 
applications.


The question of how resources are treated in the workflow model is actually 
a quite interesting one, possibly directly related to what kinds of 
applications a workflow model (system) can support.  It seems that no 
standardized solutions are ready (see mention of WfMC's RFC above).

Some applications give very little importance to how resources interact 
with the workflow process.  This is typically the case where resources are 
data that sit in some repository and can be used (at least read only) 
without limit and concurrently from many actions/tasks.

In other apps, such as LIMS, resources have a quite central role in the 
workflow.  In a lab the main resource are samples/specimen.  They exist 
physically and have to be moved around, subsampled, etc.  The LIMS should 
be able to track these resources as they move through the lab (guided by 
the work process).

Another class of resource-centric workflow are bioinformatics 
applications.  Systems such as PIPER (open source, but alpha or pre-alpha) 
(http://bioinformatics.org/piper/) and Khoros 
(http://www.khoral.com/ideas/technology/cantata.pdf) actually speak of data 
flow (generalizable to resource-flow) and model how data/resources move 
around in the process.  Every action node has then input and output 
resources.  In my thinking, this is also the most natural approach for LIMS 
applications (see http://www.sistema.it/labinfo/topics_3.html#Relationships 
between Entities).

>How hard would it be to make PROforma interoperate with one of the generic 
>workflow standards?

Conceptually, I believe the limiting factor is the process model.  On the 
surface, it seems that a PROforma workflow definition may be translated 
into the WfMG Process Definition Language, but the reverse is not true in 
the general case.

This probably means that a 3rd party workflow engine cannot ask a PROforma 
engine to enact a workflow defined outside PROforma.  It can however 
request the enactment of an already defined PROforma process.

A PROforma workflow engine can possibly request a WfMC workflow engine to 
enact a process defined within PROforma--but all the special decision 
support features would get lost on the way...  But take all that as a very 
rough line of thought...

Looking forward to your comments and see whether you understood PROforma 
the same way...

cheers
