[scxml] Is there any visualization tool ?
Hallo,
Is there anybody who knows visualization tools that can generate a state graph based on a scxml document ?
Thanks,
Frederik

Correct, its one per modeling tool, and thats a drawback. I have
nothing against others taking the XSLT approach, clearly as you show,
others are having good success with it. Might come down to personal
preference.

I do not think XSLT is fragile at all and specially
for XML Transformations I prefer it over any DOM or
SAX API approach. There are interesting efforts and
results like uml2svg [1] (to visualize XMI it uses an
XSLT[2]) in this area btw.
In any case while both solutions (with and without
XSLT) could be fine, with the XSLT one you get the
advantage of separation of concerns between the XML
Mapping (XMI to SCXML) and the graphical tool you
select to use. In that way of course changes to the
specification do not affect the work you do for any of
the specific plugin implementations (You need a plugin
for each single modelling tool you want to use able to
convert from specific graphical solution to XMI).

You got the plugin part right, but it should be a first-class
transformation plugin (each set of tooling has their own APIs,
Rational has a transformation API that is useful here). XSLT is going
to be fragile (not to mention tricky to begin with -- have you seen
the raw XMI ;-)

Indeed, those are the parts that add significant value to and from the
modeling layer. Given the demand, I think its just a matter of time
before someone decides to make that investment, and additionally make
it available to others. There are actually two transforms in this
discussion:
(a) UML state machine / activity diagram --> SCXML document
(b) SCXML document --> some visualization (such as a UML state machine diagram)
I believe (a) has come up a few times on the list, but this is the
first thread I've seen that asks for (b). Both have their place.

Hi Rahul,
I went back to the archives and I am just wondering if
you found out if the plugin to convert from "EMF model
for the statechart diagram" to "its SCXML document
serialization" is going to be available for free?
On the other hand it is clear that we need something
like:
UML <=A=> XMI <=B=> SCXML
where A=Graphical UML tool (Rational Modeler for
example)
and B=XSLT
The whole functionality could be accomplished thru a
plugin made for Rational Modeler and the main task is
just to write the XSLT part.
Of course if the plugin has already be developed
applying DRY we should just get is, use it and extend
it if necessary (SCXML is still a Draft so some
extensions will be necessary).
Thoughts?
Thanks,
-Nestor

this is becomming a good candidate question to go to
FAQ ;-)
Of course I as the rest of us I cannot wait to see
such a tool in the market.
Interesting link, however given the fact that SCXML is
XML I see more suitable to user XSLT to translate from
SCXML to State Chart Diagrams UML 2 using either
Rational or any other UML tool XML export
capabilities.

Not that I'm aware of.
There are, however, open source visualization tools such as UMLGraph
[1] that work for class and sequence diagram generation. It will
worthwhile to look at that and see how much effort it is to add
support for state machine diagrams, given the SCXML documents as
starting points, if anyone is interested.
