to me this makes all sense to start working on this - even just for
testing (without any on-the-fly re-projection) and see how it goes.; to
see where problems would be, etc.

... i think Peppe means that in every country there are typical
coordinate systems (in Austria there are about 12 -15).
If the user add some data which are "wrong" located and wants to
tranform it OPEN JUMP will recommend typical EPSG-Code basing on
the EPSG of the project. This does not mean "on the fly
transformation"?

Hi,
I fear that you aim at similar “on the fly CRS transformation”
than QGIS has. I admit that it would be nice to be able to use
layers with different native SRIDs together in OpenJUMP project
but I am pretty sure that it will introduce new problems as well
for example when editing data or making measurements in the
non-native SRID. I hope that the current robust but not so much
SRID aware behavior can still be preserved in the future as an option.
You did not mention JML data files but I think that they could
have an additional element for storing the SRID.

Hi all,
The title explains what is my idea. In a possible future we can
extend OJ projection capabilities. And the 1st step I would
explore is to add SRID code to a task (to centralize possible
transformations) and unit of measurements (retriving from SRID,
which will affect other plugins/tools like measure tools, measure
area/length, display scales etc, especially for Geographic
coordinate systems).
I gave a look at Task class , should I implement (srid and unit)
as properties into the associate xml file? Does it breaks
compatibility?
Thanks for the help
Peppe
