# Entity References

Many CLI options and API parameters accept **entity references**—a consistent string format for referring to entities (and optionally a sub-resource) across the platform.

---

## Format

```
[workspace/]entity_name[#fragment]
```

| Part          | Required | Description                                                                                                               |
| ------------- | -------- | ------------------------------------------------------------------------------------------------------------------------- |
| `workspace`   | No       | Workspace name. If omitted, the workspace is taken from your current context (CLI `--workspace`, SDK client, or request). |
| `entity_name` | Yes      | The entity's unique name within the workspace.                                                                            |
| `#fragment`   | No       | Optional entity-specific path or parameters (e.g. a file path within a fileset).                                          |

---

## Examples

* **`default/my-fileset`** — Fileset named `my-fileset` in workspace `default`.
* **`my-fileset`** — Same entity when your current context already specifies the workspace.
* **`prod/my-fileset#data/training.parquet`** — A specific path inside that fileset (when the entity type supports fragments).

Can use the full form `workspace/entity_name` to keep the reference unambiguous regardless of context.
