## Common Data Model

- [Procurement](https://altiumdeveloper.github.io/cdm/subsets/procurement/) — Models bills of materials: BOMs kept in a Workspace and worked on in the BOM Portal (managed and consolidated BOMs) with their releases, global BOMs, which are not tied to a Workspace, and BOM lines with their alternate and substitute parts and the issues found when a BOM is analysed. It corresponds to the Altium 365 BOM Portal.

## Entities

API types in this bounded context that represent Common Data Model (CDM) entities. The IRI is the entity's stable identifier in the CDM.
