Tag a data model
Add a version tag to a data model and optionally set up a connection to swap to for a specific version of the data model.
### Usage notes
- Retrieve the **dataModelId** by calling the [/v2/dataModels](https://help.sigmacomputing.com/reference/list-data-models) endpoint.
- Retrieve the **tag** by calling the [/v2/tags](https://help.sigmacomputing.com/reference/list-version-tag) endpoint and using the `name` in the response.
- Retrieve the **connectionId** to use as the **fromId** or **toId** by calling the [/v2/connections](https://help.sigmacomputing.com/reference/list-connections) endpoint.
- If your data model includes a source that is not mapped to a new source, that source is not swapped.
- When swapping data models used as the source for the data model:
- You can only swap a data model source to another version of the same data model source. You cannot swap a data model source to a table in your data warehouse or a dataset.
- When you swap sources from one data model version to a new one, specify the version tag of the data model that you swap to with `toVersionTagId`:
- To swap to the latest published version of the data model, specify `toVersionTagId` as `null`.
- To swap to a specific tagged version of the data model, specify the `toVersionTagId` of the data model.
- If the data model already uses a specific tagged version of a data model as a source, use `fromVersionTagId` to indicate which tagged version to swap from.
- To swap from the latest published version of the data model, specify `fromVersionTagId` as `null`.
- To swap from a specific tagged version of the data model, specify the `fromVersionTagId` of the data model.
- To retrieve the `fromVersionTagId` for a data model used as the data model source, call the [/v2/dataModels/{dataModelId}/sources](https://help.sigmacomputing.com/reference/list-data-model-sources) endpoint and use the `versionTagId` in the response.
- To retrieve the `versionTagId` for a data model, call the [/v2/dataModels](https://help.sigmacomputing.com/reference/list-data-models) endpoint and use the `versionTagId` in the response.
