Compositing deltas when merging artifacts in a version control system

Embodiments of the present invention address deficiencies of the art in respect to merging artifacts in a version control system and provide a novel and non-obvious method, system and computer program product for compositing deltas when merging artifacts in a version control system. In one embodiment, a method for compositing deltas for artifacts can be provided. The method can include generating deltas for a contributor artifact of an ancestor artifact, identifying interrelated ones of the deltas and grouping the interrelated ones of the deltas into a composited set of deltas. The method further can include rendering the composited set of deltas in a hierarchical view of a compare view for a version control data processing system in a development platform.
