Objective
Slicer4 MRML node referencing mechanism needs some design improvement, as for each referenced node in each node type about 10 methods shall be added/updated manually. This is very difficult to do, often done incorrectly. The goal is to discuss the details and design robust, simple, centralized implementation of all node reference updates for save/load, undo/redo, scene import features
Approach, Plan
A potential solution would be to introduce a "ReferencedNodes" list, which would store pointer, ID string, node type name, and observers for each referenced node instead of adding separate member variables for these manually. This list could be fully maintained by the Copy, UpdateScene, UpdateReferenceID, UpdateReferences, ReadXMLAttributes, WriteXML, etc. methods implementation in vtkMRMLNode base class. Developers would just need to add an item to the ReferencedNodes list and all the rest would be handled by the MRML framework.
Progress
Not yet available
Delivery Mechanism
This work will be delivered to the NA-MIC Kit as changes in the Slicer4 core and in the SlicerRT extension
