Backlink for References

Hi,

is there a possibility in MPS to define something like a List in a Node which is possibly referenced by other nodes to get all referencing nodes easily (like in EMF f.e.)? I know how to fetch them programmatically ;-) ... just for ease of use.

Mirko,

I am not familiar with EMF. Could you give an example of what you want to define? You want to reference a list inside of a node, right?

I understood what you want. We had this features, it was called back references. But eventually it was dropped since we can't load all available models since it will slow MPS down considerably. On the other hand, we have find usages operation in smodel language which you can use to get all back references but it is quite expensive.

Hi Konstantin,

ok, i understand the performance impact.

I will have a look at the usages operation.
