2 years of Ruote : some kind of census
John Mettraux
It's been two years since I started OpenWFEru / Ruote.
I was wondering who's using it, I'd like to know what's the size of
the tribe approximately. Here are my questions :
1). which version of Ruote are you using ?
2). in what kind of project / industry ?
3). are there things that you'd like to see appear ? which direction
would you like the project to take ?
4). can I use the name of your company/org as a reference ?
Feel free to answer or not.
My answers :
1). 0.9.18
2). inside of a CMS to drive approval processes (on top of JRuby), 40
instances deployed
2b). next project is about processes driving the commit/checkout of
complete web site snapshots
3) these days, working on 0.9.19 and
http://jmettraux.wordpress.com/2008/09/29/ruote-on-rails-20/
4). yes, http://wsp.macnica.co.jp/
Best regards,

1). which version of Ruote are you using ?
2). in what kind of project / industry ?
3). are there things that you'd like to see appear ? which direction would you like the project to take ?
If community is interested in some of these features we could try to integrate them into trunk.
4). can I use the name of your company/org as a reference ?

And my answers are:
1). which version of Ruote are you using ?
0.9.18
2). In what kind of project / industry ?
NASA SensorWeb for Emergency & DIsaster Support Worldwide. Aerospace/
Remote Sensing
3). Are there things that you'd like to see appear? which direction
would you like the project to take ?
I would love to see convergence with WfXML-R for the REST API and XPDL
2.0 ingest.
A BPMN editor that generates XPDL and connects to OpenWFE would be nice.
4). can I use the name of your company/org as a reference ?
Vightel Corporation / NASA Goddard Space Flight Center.

Hi Diego,
I've seen your post on the WfXML-R list
(http://groups.google.com/group/wfxml/browse_frm/thread/8b4d1477e079bb30)
I'm following WfXML-R as well, but have had to implement something meanwhile.
I don't know how you've devised your project, maybe it could be an
entity on its own (http://github.com/search?q=ruote). I wouldn't have
the time to help directly, but I could certainly try to adjust Ruote
to it if it's thus visible.
I've also got a revised XML ( + JSON) serialization going on
(http://github.com/jmettraux/ruote/tree/master/lib/openwfe/representations.rb).
Maybe another way of collaborating would be for you to "advise" on the
further REST work. I'm open to your suggestions and requirements.
Thanks for your answers,
John Mettraux

Hi Pat,
thanks a lot for your answers.
We're (John + Diego) waiting for the final WfXML-R, keep up at it.
About XPDL, I've got something of a beginning at :
http://github.com/jmettraux/ruote-transition, turning XPDL into Ruote
trees of expressions. Nobody's been using it so far.
I've been struggling lately to make Ruote web interfaces closer to
this "tree of expressions" representation of process definitions and
instances, meaning that Ruote definitions are very close to Ruote
execution models.
Advantage : what you see is what gets executed (and you can modify the instance)
Disadvantage : Ruote will never be a "direct XPDL" engine (well XPDL
is a serialization format after all). There will always be a
compilation step from XPDL to Ruote expression trees.
On the other hand, I've been doing some preparation work on a
potential <graph> expression for Ruote that would make XPDL -> Ruote
'compilation' easier. We'll see.
So your idea of finding a decent BPMN editor with XPDL serialization
still prevails.
Thanks for your support,

Hello Nicholas,
the engine itself is quite independent from ruote-web[2] and
ruote-rest... You can use it as a plain library. Maybe you meant
something else.
Ruote-rest is based on Rack (http://rack.rubyforge.org/) which
provides a convenient platform on top of many [ruby oriented] web
servers.
Ruote-web2 is Rails based indeed, so all the Rails knowledge applies indeed.
Thanks for your support, kind regards,
Nicholas Petrella
I honestly haven't looked much yet at ruote-web 2. I ran into a lot of problems when I tried to use both ruote-rest and ruote-web on top of the same engine. I figured ruote-web2 would be much improved so I am glad to hear that. Once we finalize all the other parts we are putting with the engine (all of our python code), I will give the new version a try both because I am really excited about it and to give you some more QA.

Ah OK, understood :)
Yes, I really want ruote-web2 to be a superset of ruote-rest.
Thanks in advance for the QA, cheers,

Just got the revision form Keith Swenson. His team has something
working and they are getting ready to give more feedback. As we get
more people implementing it, we get start tuning that spec. Stay
tune. This is high priority now.

Not sure what that means but I trust you. :)

Can't take credit for it though. This is Community Work. The Way it
should be.
Keep up the good work.

processes between two or more running engine instances would be nice
(so that you can run ruote-web2 or something similar ;-) in a mongrel
cluster for example). Perhaps I should try the DBPersistedEngine for
that -- but I don't have need for this right now.

Sorry because I am writing three weeks late, but I hope this will not be the usual way.
In our project, we are working with openwferu and some extensions over ruote-web. I hope we can contribute with some pieces of this effort. My idea is to analyze ruote-web2 and see what our improvements we can integrate (if it is possible).
The most interesting thing is we have planned two subprojects:
1) One graphical editor of workflows on Flex tecnology.
2) And a graphical editor of web forms also on Flex, but these forms will be only visible in a Flex form renderer we are writing too.
If somebody is interested in some of these projects we can colaborate in aid for community.
Regards.

Hi Diego,
that's great news. Maybe you should just start the projects and see if
people follow your efforts. I'm always here for the interfacing with
the core.
BTW, how did your Rails conference presentation go ? Do you have the
slides available somewhere ?
Cheers,
Diego Moreno
the conference went very well (IMHO). There were some questions during the conference and also some people made me some more questions out of the conference. I hope I did a good salesman job with openwferu :)
I have uploaded the slides on:
http://www.slideshare.net/d_moreno/workflows-on-rails-presentation/
And you can see the conference called "Workflows on Rails" in:
http://isabel.dit.upm.es/component/option,com_docman/task,cat_view/gid,132/Itemid,74/
Both are in Spanish. Sorry :(
With the subprojects, our group are decided to initiated them. When we can start the development we will announce our advances to the list.
Best Regards.
Diego Moreno
John Mettraux
So many people speak Spanish, it's perfect.
That's an excellent presentation. I like the fact you started with
"act as a state machine" and you gave the broad view on Ruote, thanks
a lot !
If you need any assistance for starting the projects I'd be glad to help.
Thanks again !

Hello Diego,
I was just wondering if your group had had a look at
http://bpt.hpi.uni-potsdam.de/Oryx
It's not flex based, but it's a tremendous effort. It is graphical
editor for processes and it has a webform editor IIRC.

Thanks Torsten ! Thanks to you all for your answers !
Cheers,

Pat, we have some ideas to XPDL support. When project starts I will tell you. So, we can choose the better way to achieve this XPDL support.
