# Example 1: Defining a Dataset with DICOM Data

## The Data Schema

The Data Schema can be uploaded as a CSV to the Rhino Web UI or added directly to the Rhino Web UI through the built-in Data Schema editor. For this example, we will create this Dataset within the UI and name it Stroke Schema.

|                          |                   |                   |                   |                   |                               |

| **Secure Access**        | Allowed (Enabled) | Allowed (Enabled) | Allowed (Enabled) | Allowed (Enabled) | Allowed (Enabled)             |

## The Dataset's Tabular Data

The tabular data CSV file is prepared within the institutional firewall from data in clinical systems and then copied via SFTP to the Rhino Client.

|                                                       |        |      |                 |

| 1.3.12.2.1107.5.4.3.4975316777216.19951114.94101.16   | f      | 0.95 | True            |
| ...                                                   | ...    | ...  | ...             |

For this example: Let’s say this tabular CSV file was copied via SFTP to the following location on your Rhino Client: `/rhino_data/uploads/stroke/dataset1.csv`

## The Dataset's DICOM Data

All DICOM files associated with the studies in the tabular data file are queried from the PACS, de-identified, and then copied via SFTP to the Rhino Client.

The Rhino Client doesn’t require or expect any specific file structure, so all `.dcm` files can be put under the same directory, under sub-directories (e.g., for each study or series), or a mix of the two.

For this example, let's say we place our DICOM data in the following locations on our Rhino Client:

* `/rhino_data/uploads/dicom_data/`

`1.3.12.2.1107.5.4.3.11540117440512.19970422.140030.46.dcm`

* `/rhino_data/uploads/dicom_data/another.dcm`
* `/rhino_data/uploads/dicom_data/1.dcm`
* `/rhino_data/uploads/dicom_data/study1/1.dcm`
* `/rhino_data/uploads/dicom_data/study1/2.dcm`
* `/rhino_data/uploads/dicom_data/study2/1.dcm`
