Existing Tool Support for Collaborative Work

• Focused on source code (text)

• Different level of abstraction:– Files instead of Models– Text instead of Model Elements

• Problems and Consequences– Change Tracking is difficult– Conflict Detection is inaccurate – Merging is error-prone

Model Change Tracking

• State-based:

– Changes derived after they occur

– Derived by differencing state before and after

• Operation-based:

– Changes recorded while they occur

– No differencing required
