# Terminology and Concepts
<a name="qs-developer-terminology"></a>

This section provides a list of terms for development in Amazon Quick Sight. 

**Caller identity:** – The identity of the AWS Identity and Access Management (IAM user making an API request. The identity of the caller is determined by Amazon Quick Sight using the signature attached to the request. Through the use of our provided SDK clients, no manual steps are necessary to generate the signature or attach it to the requests. However, you can do it manually if you want to. 

**Invoker identity:** – In addition to the caller identity, but not as a replacement for it, you can assume a caller’s identity through the IAM `AssumeRole` API when making calls to Amazon Quick Sight. AWS approves callers through their invoker’s identity. This is done to avoid having to explicitly add multiple accounts belonging to the same Amazon Quick Sight subscription. 

**Quick Sight ARN:** – Amazon Resource Name (ARN). Amazon Quick Sight resources are identified using their name or ARN. For example, these are the ARNs for a group named `MyGroup1`, a user named `User1`, and a dashboard with the ID `1a1ac2b2-3fc3-4b44-5e5d-c6db6778df89`:

```
arn:aws:quicksight:us-east-1:111122223333:group/default/MyGroup1
arn:aws:quicksight:us-east-1:111122223333:user/default/User1
arn:aws:quicksight:us-west-2:111122223333:dashboard/1a1ac2b2-3fc3-4b44-5e5d-c6db6778df89
```

In the following examples show ARNs for a template named “MyTemplate” and dashboard named “MyDashboard”.

1. Sample ARN for a template

   ```
   arn:aws:quicksight:us-east-1:111122223333:template/MyTemplate
   ```

1. Sample ARN for a template, referencing a specific version of the template

   ```
   arn:aws:quicksight:us-east-1:111122223333:template/MyTemplate/version/10
   ```

1. Sample ARN for a template alias

   ```
   arn:aws:quicksight:us-east-1:111122223333:template/MyTemplate/alias/STAGING
   ```

1. Sample ARN for a dashboard

   ```
   arn:aws:quicksight:us-east-1:111122223333:dashboard/MyDashboard
   ```

1. Sample ARN for a dashboard, referencing a specific version of the dashboard

   ```
   arn:aws:quicksight:us-east-1:111122223333:dashboard/MyDashboard/version/10
   ```

Depending on the scenario, you might need to provide an entity’s name, ID, or ARN. You can retrieve the ARN if you have the name, using some of the Quick Sight API operations.

**Quick Sight dashboard:** – An entity which identifies Quick Sight reports, created from analyses or templates. Quick Sight dashboards are sharable. With right permissions, scheduled email reports can be created from them. The `CreateDashboard` and `DescribeDashboard` API Operations act on the dashboard entity.

**Quick Sight template:** – An entity which encapsulates the metadata required to create an analysis or a dashboard. It abstracts the dataset associated with the analysis by replacing it with placeholders. Templates can be used to create dashboards by replacing dataset placeholders with datasets that follow the same schema that was used to create the source analysis and template.

**Quick Sight user:** – This is an Amazon Quick Sight user identity acted upon by your API call. This user isn't identical to the caller identity but might be the one that maps to the user within Amazon Quick Sight.
