Namespace: [Grasshopper2.Data.Meta](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.data.meta.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```

Enumerates all standard meta data entries considered 'transient', i.e. data which oughtn't be copied to offspring data.

## Values

| Name | Value | Description |
| --- | --- | --- |
| None | 0 | No transient data is implicated. |
| RhinoId | 1 | The [StandardNames.Rhino.Id](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.rhino/id.md) datum is implicated. This value oughtn't be copied because that makes downstream data think it's referenced. |
| UserText | 2 | The [StandardNames.Record.UserText](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.standardnames.record/usertext.md) datum is implicated. This value oughn't be copied because it stores the string from which the value was parsed. This is not relevant to modified downstream data. |
| Transient | 4 | All entries marked as [MetaName.IsTransient](https://developer.rhino3d.com/api/gh2/type/grasshopper2.data.meta.metaname/istransient.md) are implicated. |
| All | 7 | All data considered transient. |
