Which EMFT should I use to output SVG? [message #485894]

EMFT newbie. I searched the news group and found nothing. And since I am
totally new to EMTF I may just be looking in the wrong place.

I want to output some text files from the model but I also want to output
a SVG diagram. Which EMTF will do this EMF, EMFT, MDT or M2T? Or some
other one I don't know about.

Paul,

It sounds like you'd want to use some M2T technology to produce text
files from models. If you're using GMF for your diagrams, I'm not sure
if it provide export to SVG....

Just to be clear. Let us assume GMF does output SVG. What you are saying
is that M2T will output both the text file and the SVG file. In other
words M2T will invoke the GMT "thing" to output the SVG file. And that
getting M2T to invoke GMT is just a download and a configuration task, and
not writing code, correct?

As a side node, SVG is just a dialect of XML for 2D graphics.

Actually, your original question is pretty vague. It's not entire
clear what the relationship is between your model and the text or SVG
you want to output. Vague questions usually result in vague answers...

I know. It's just not clear where the 2D graphics come from. If you
have a GMF diagram view, it's definitely possible to save it as SVG.
But I'm not sure if that's your actual question.

What I was hoping is that I could take data from the model and create the
SVG directly. I have the SVG drawing already done. The only thing I
would need the M2T tool to do is replace some values in XML elements in
the SVG. I don't want to re-create the drawing in GMF just to get the
SVG output.

Thanks for your time.

I am not sure what is the problem. Nevertheless M2T Xpand can be an answer.

Part of M2T Xpand is Xtend an model-to-model transformation language. In
Xpand/Xtend, XML file can be directly manipulated like a model, as long
as there is an XML Schema for it. So one can load the SVG file, load
data model and then merge them with Xtend. Things to know: Xtend, XSD
Adapter, MWE.
Here is old documentation of XSD Adapter, so you can check if this is
what you need
http://www.openarchitectureware.org/pub/documentation/4.3.1/ html/contents/xsd_reference.html

Unfortunately SVG is not the best formed XML file out there and many XSD
files need to be refined before they are usable as EMF metamodels.
Hence, using model-to-model transformation may be inefficient. That
depends on your exact context.

You can also split your existing SVG file and put it into some code
generation technology (thus, M2T projects). Xpand can handle that well,
as the rest of M2T projects.

All that said, I think it would be easiest to use Groovy, an EMF adapter
and one of template engine integrated with Groovy, that evaluate
${a.b.c} expressions. Or even plain Java. But that is a guess, as
problem definition is ambiguous.
