Data model in Altinn Studio

How to import or view the data model in Altinn Studio.

To get to the new data model page in Altinn Studio, simply open an app and select Data model from the top menu.

When opening the page, a dialog with some information about the page is shown. You can choose to not have this dialog open every time by clicking Do not show again. As long as you use the same computer/browser, the message will not be shown again.

Upload / show data model

The data model defines which data that can be sent in via an app, and which format it should be on. In order to upload an existing data model, the model must be defined as an XSD in an external tool.

Each app needs at least one data model.

1. Open the app from the dashboard.
2. Select the Data model meny item
3. Click Upload data model and choose an XSD in the file browser.
4. Click Open in the dialog to upload the XSD

The data model is then parsed, and a C# class and JSON schema are generated from the XSD. You can see a tree view representation of the data model in the tool once it has been uploaded.

Create new data model

In addition to uploading a data model, a new model can be created from scratch.

1. Click Create new data model
2. Type in the name of the model.
3. Click Create model to create the model.

The new model is created from a template, and has a single example field called e1.

Select data model

Switch between already uploaded/created data models by using the dropdown list of available models in the top toolbar.
