Explains authoring and the system of record for master data
Which sources create or change each attribute, and one system of record per attribute among them (DMBOK2 ch. 10; ISO 8000-110).
Can AI do this?
AI does this well Most of the tested AI models master this. 4 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 100% | Mastered |
| gpt-6-luna | Low cost | 100% | Mastered |
| claude-haiku-5-5 | Low cost | 100% | Mastered |
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: Which sources create or change each attribute, and one system of record per attribute among them (DMBOK2 ch. 10; ISO 8000-110).
How it is assessed: Answers a written question on the master data authoring correctly
