Schema Reference
UModel schemas are organized as a layered standard. This reference documents the L0 Core abstractions — the base vocabulary every model is built from.
Standard layers
| Layer | Name | Status |
|---|---|---|
| L0 | UModel Core — EntitySet, DataSet, Link, Storage | Documented below |
| L1 | Semantic Conventions — shared service/host/pod/database semantics | Roadmap |
| L2 | Domain Profiles — DevOps, APM, Kubernetes, AIOps, … | Roadmap |
| L3 | Conformance — automated standard-compliance checks | Roadmap |
See the contribution guide for how to propose L1–L3 content.
