# SysSdmSystemModelVersion

**EXPERIMENTAL**

### Experimental

> **Caution:** Not production-ready. It may change or be removed without notice. See [Lifecycle](https://altiumdeveloper.github.io/platform-api-docs/guides/lifecycle.md).

### Common Data Model

- [System Model Version](https://w3id.org/altium/cdm/system/SystemModelVersion) — A specific version of a system model, capturing the state of the system design at a particular point in time.

  - IRI: [`https://w3id.org/altium/cdm/system/SystemModelVersion`](https://w3id.org/altium/cdm/system/SystemModelVersion)
  - GRID: `grid:workspace:{workspace-id}:system-design:sdm-version/{id}`
