Hi, I am exporting models from MPS. Basically I export all the models as trees, this schema works decently with children but it does not work with references. To do that I would need to assign an ID to every node. Does not have they already an ID? How can I access it?

Yes, all nodes in MPS have ids, unique in scope of model. You can obtain the id from SNode class: SNode.getSNodeId().

If you have a node<Concept> - typed variable, you can cast it to SNode or use the "downcase to lower semantics level" operation:

node<Concept> n;
n/.getSNodeId();

For dearest Googlers, I'm using this now:

interface concept behavior IIdConcept {                                       public string getId() { 
    this/.getConcept().getName() + this/.getNodeId().toString(); 
  }
}                                                  
// For
concept GeographicSite extends BaseConcept implements IIdConcept 

// It makes Ids like this:
// GeographicSite8458086500259349004
