# DesReuseBlockRevision

Reuse block revision information.

### Common Data Model

- [Reuse Block Revision](https://w3id.org/altium/cdm/library/ReuseBlockRevision) — A revision of a Reuse Block: its schematic and/or PCB content as saved into the Workspace at one point in time, with its own lifecycle state. Editing a reuse block saves it into the next revision.

  - IRI: [`https://w3id.org/altium/cdm/library/ReuseBlockRevision`](https://w3id.org/altium/cdm/library/ReuseBlockRevision)
  - GRID: `grid:workspace:{workspace-id}:library:reuse-block-revision/{id}`

### Returned By

[`desReuseBlockRevisionById`](https://altiumdeveloper.github.io/platform-api-docs/reference/library-management/operations/queries/des-reuse-block-revision-by-id.md) query · [`desReuseBlockRevisionsByIds`](https://altiumdeveloper.github.io/platform-api-docs/reference/library-management/operations/queries/des-reuse-block-revisions-by-ids.md) query

### Interfaces

#### [`Node`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/interfaces/node.md) interface

The node interface is implemented by entities that have a global unique identifier.

```graphql
type DesReuseBlockRevision implements Node {
  comment: String!
  description: String!
  id: ID!
  lifeCycleState: DesLifeCycleState!
  name: String!
  pcbSnippet: DesDownloadableFile!
  schematicSnippet: DesDownloadableFile!
}
```

### Fields

#### `comment` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar
