# Library Management

Managed components, component templates, parts, symbols, footprints, datasheets, reuse blocks and library search.

## Common Data Model

- [Library Management](https://altiumdeveloper.github.io/cdm/subsets/library/) — Models the components stored in a Workspace and their revisions, the symbols, footprints, parameters, datasheets and part choices that make them up, and the component templates they can be created from. It also covers manufacturer parts in the Workspace part catalog, part requests, and reusable design content such as reuse blocks, managed sheets, and schematic and PCB snippets. It corresponds to Workspace components and design reuse in Altium Designer and Altium 365.

## 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.
