# Type Alias FilesEditSessionMetadataValue

```typescript
FilesEditSessionMetadataValue: CloudSyncJsonValue
```

Types: [CloudSyncJsonValue](core.Supporting_types.CloudSyncJsonValue.md)

Plain-JSON value carried opaquely in edit-session `metadata`. Matches the host's metadata schema exactly (it canonicalizes, size-caps, and consent-digests the bag, refusing anything that is not plain JSON data), so functions, symbols, `undefined`, and non-finite numbers are refused at `files.openWith` rather than silently dropped.
