Explains one catalogue entry per object
An object harvested from several tools is one entry with several sources, matched on its physical reference, so that lineage, ownership and classification attach to one node (DMBOK2 ch. 12 §2.4.1).
Can AI do this?
AI does this partly Some of the tested AI models master this; others do not show it. 2 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 91% | Mastered |
| gemini-3.5-flash-lite | Low cost | 53% | Not shown |
| gpt-6-luna | Low cost | 91% | Mastered |
| claude-haiku-5-5 | Low cost | 53% | Not shown |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: An object harvested from several tools is one entry with several sources, matched on its physical reference, so that lineage, ownership and classification attach to one node (DMBOK2 ch. 12 §2.4.1).
