# Datasets

Using the **Datasets** screen, users are now able to manage daily RDFs for any Dataset in the system. On top of that, the **Datasets** provides to ability to associate a [**Metadata Defenition**](/2.10.2/data-pipelines/metadata.md#step-1-defining-metadata-fields) with a **Dataset** enabling tagging of services.

### Deleting days in a Dataset

In order to remove certain days (or: [Daily RDFs](/2.10.2/advanced/digging-deeper/databases.md#daily-rdfs)) from a Dataset, browse to the **Data Pipelines > Datasets** menu and select the **Dataset** from which you want to delete certain days.

Then click the red trashbin icon next to each day for which you want to remove its data:

![Deleting days from a Dataset](/files/-M-KirlpJkJBVhVLwTw1)

Once each day has been set to delete, confirm your selection by clicking the **Update** button:

![Confirm Deletion of Daily RDFs](/files/-M-Kk-JIa-a3kyRFsLNQ)

### Deleting an entire Dataset

In order to d elete the entire **Dataset** the *Delete* button in the lift bottom corner can be used:

![Click OK to delete the entire Dataset](/files/-M-KmeF6ufNRFzxLDAmB)

After confirmation the entire **Dataset** will be deleted from disk.

### Associating Metadata to a Dataset

In order to use **Metadata** for Services, a **Metadata Defenition** needs to be associated to the corresponding **Dataset**. This can be achieved by opening the **Data Pipelines >** **Datasets** management screen, then selecting the **Dataset** for which you want to configure **Metadata:**

![Associating Metadata to a Dataset](/files/-M-Ko0YwaFtI-VN0iPrb)

Afterwards make sure to click the *Update* button to ensure your changes are saved. Now it is possible to configure Metadata values for all the [**Services** ](/2.10.2/reports/services.md#filters-and-reporting-depth)in this **Dataset**.
