Relations between some archimate elements are not supported - e.g. between Data Object and Artifact there can be the "Realization relation" (Archimate 3.0). And it is not supported...
Hi, yes we're aware of discrepancies in the ArchiMate 3.0 spec regarding relationships. The relationships in Archi 4 beta are taken from the relationship matrix in the documentation. We are tracking this here - https://github.com/archimatetool/archi/issues/164 As and when these are agreed we will correct them in Archi.
