Hello All

I want to somehow facilate the opening of .xmi files of concrete model in
a DSL Editor.

For Example consider:
sample1.xml
------------
<?xml version="1.0" encoding="UTF-8"?>
<datatypes:PrimitiveDataType xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:datatypes="http://q-impress.eu/samm/datatype"
id="_e94SQF8FEd6mb4izF2cfPA" documentation="" name="pr_01" type="int"/>

------------------------------------------------------------ ---------
I want to be able to open this .xml file in the DSL editor as:

------------------------------------------------------------ ---------
PrimitiveDataType id:"_e94SQF8FEd6mb4izF2cfPA"{
name:"pr_01";
doc:"";
type:1;
}
------------------------------------------------------------ ---------

Is there any way that this can be accomplished?

If my objective is unclear then, pls let me know and I shall elaborate it.

Thanks.

Durga

Durga,

This is possible, but I don't think that it is simple. The main
issue arises because you have two concrete syntaxes for your
model. You could create an Xtext based DSL that uses your
'editor' syntax. However, this would also persist your model in
the same syntax.

One way to get around this would be to intercept the load
and save methods of the Xtext DSL and copy the contents
of the resource to/from one with an .xmi extension and use the
load and save methods on this resource. Note, this only
works if the two concrete syntaxes do truely share a single
meta-model.

Andy.

Hi Durga,

I think I understood what you described, however I've no idea about the
usecase. Maybe there are other ways to achieve what you want. Would you
please be so kind an elaborate a bit on it from a more user oriented view?

Andy was right, there would be some work to do, if you want to create
such a projection-based editor for your xmi-file.

Regards,
Sebastian
