Hi, is there a way to update the position of some mappings so that they always stick to the edge of the diagram (at least at the top and on the left).

Stuff like: my diagram shows an activity (without the activity container), and the activity parameter nodes should be shown on the edge of the diagram.

Hello
You have the ability to define the position of the nodes at the node's creation. You just have to call a java service (from a ChangeContext operation for example) to do the job (aql:self.myservice())
Here are some tips to help you write the java code https://wiki.eclipse.org/Sirius/Cookbook#Set_Coordinates.2FPosition_at_node_creation_using_a_Node_Creation_Tool

Note that it does not prevent the user to move the node afterward.

If you want to prevent the move of the node after it has been created you will have to do much more complicated work.
You will need to provide your own IGraphicalEditPart and your own EditPolicy for this node. To do that, provide a org.eclipse.gmf.runtime.diagram.ui.services.editpart.AbstractEditPartProvider
As an example, you may install interaction [1] meta-model to have a sequence diagram in Sirius.
The lifeline can not be dragged downward. To see what has been done take a look to org.eclipse.sirius.diagram.sequence.ui.tool.internal.edit.part.InstanceRoleEditPart
org.eclipse.sirius.diagram.sequence.ui.tool.internal.provider.SequenceDiagramEditPartProvider is the provider of this EditPart.
