Techniques of consolidation and customization of graph-based models are disclosed. A first graph-based representation of a first model can comprise a first set of nodes corresponding to data items of the first model, and a second graph-based representation of a second model can comprise a second set of nodes corresponding to data items of the second model. Matching nodes between the first set of nodes and the second set of nodes can be identified. Matching topological features between the first set of nodes and the second set of nodes can be identified. Matching dependency characteristics between the first set of nodes and the second set of nodes can be identified. A third graph-based representation of a consolidated model can be created based on the matching nodes, the matching topological features, and the matching dependency characteristics.
