Hi,

My class and I are working on a model-based tool for pervasive games
(treasure hunt-like where players perform tasks in the physical
environment) and an obvious task is following a path of locations.
Ideally a tool should allow us to combine Sirius on top of a map, e.g.
using tiling code from Nebula's GeoMap widget. This leads me to the
following two questions:
- Is it possible / easy to customize the background, so I can show a
map underneath?
- Is it possible to compute the position of diagram elements from data
in the underlying object?

To do that you can use the GMF API to provide your own DiagramEditPart
which inherits of Sirius DDiagramEditPart. The GMF API provides the
editPartProvider extension point to do that. And with your
DiagramEditPart you can create your own figure to display your image.

The VSM, i.e. odesign model, doesn't provide natively mean to compute
diagram elements position according to semantic change. Then you should
do it programmatically through a listener reacting to your data change
to update the GMF notation model used in Sirius.
