# Decorators

By uploading a specific CSV file, you can "shallow-rename" fields (change their display label) or hide specific properties from users without altering the underlying technical schema.

## Decorator CSV Format

Schema decorators are defined using a CSV file. Below are the specifications for the file format.

#### CSV Dialect Rules

* Separator: Comma (`,`)
* Quotes: Double quotes (`"`) must be used for strings that contain commas.

#### Columns Specification

The CSV must contain the following headers.

| Header       | Description                                                                                               |
| ------------ | --------------------------------------------------------------------------------------------------------- |
| OBJECT\_NAME | The name of the object (resource) where the property is located.                                          |
| FIELD\_NAME  | The original technical name of the property to decorate.                                                  |
| HIDDEN       | `true` or `false`. Indicates if the field should be hidden from the UI.                                   |
| LABEL        | The user-friendly name to display in the Segment Builder and Query Tool.                                  |
| HELP\_TEXT   | A short description displayed as a tooltip when hovering over the question mark (?) icon in the platform. |
| LOCALE       | The locale for the label. Currently, this must be set to `en-US`.                                         |

#### Example

Code snippet

```
OBJECT_NAME,FIELD_NAME,HIDDEN,LABEL,HELP_TEXT,LOCALE
UserPoint,id,false,User ID,Unique identifier for the user point,en-US
UserPoint,technical_hash,true,,,en-US
UserEvent,subcategory,false,Subcategory,The specific sub-category of the event,en-US
UserEvent,subcategory_id,true,,,en-US
UserEvent,title,false,Event Title,The main title or headline of the event,en-US
UserEvent,region,false,Region,The geographic region associated with the event,en-US
```

Note on Character Encoding

You must normalize strings by removing accents. Characters such as `é`, `è`, or `à` are not supported in the CSV file and should be replaced with their non-accented counterparts.

## Managing Decorators

You can manage schema decorators either through the mediarithmics user interface (Navigator) or programmatically via the API.

### Via User Interface

In the **Datamart > Object View Configuration** section of the Navigator Settings, you can use the buttons under the Schema to manage your CSV files directly.

The available actions are:

* **Upload new Decorators**: Allows you to upload a prepared CSV file to apply new labels and visibility rules. This will overwrite existing decorators for this schema.
* **Download Template**: Downloads a blank CSV file containing the required headers (`OBJECT_NAME`, `FIELD_NAME`, etc.) to help you get started.
* **Download Decorators**: Downloads the current active decorator CSV file. This is useful if you want to make edits to the existing configuration.
* **Delete Decorators**: Removes the current decorator file. The schema will revert to displaying raw technical field names, and hidden fields will become visible again.

### Via API

#### Prerequisites

You will need the following values:

* `DATAMART_ID`: The ID of your Datamart.
* `SCHEMA_ID`: The ID of the Schema you wish to decorate.
* `MICS_API_TOKEN`: Your API authentication token.

#### Retrieve Current Decorators

To fetch the existing decorator file for a specific schema:

Bash

```
curl -H "Authorization:$MICS_API_TOKEN" \
     -X GET \
     --location "https://api.mediarithmics.com/v1/datamarts/$DATAMART_ID/graphdb_runtime_schemas/$SCHEMA_ID/schema_decorators"
```

#### Update Decorators

To upload a new decorator CSV file (replacing the existing configuration):

Bash

```
curl -H "Authorization:$MICS_API_TOKEN" \
     -X PUT \
     --location "https://api.mediarithmics.com/v1/datamarts/$DATAMART_ID/graphdb_runtime_schemas/$SCHEMA_ID/schema_decorators" \
     --data-raw "$(cat path/to/schema_decorators.csv)"
```
