Viewing and modifying a Dataset schema

Once you have created a Dataset you may need to modify its schema, either to add new Concept types to it, or to modify the properties of a Concept within.

To view the schema of a Dataset and its Concepts you can click on the menu icon in the top right of a Dataset tile on the Data Graphs app homepage, and selecting the Manage link.

This will take you to a screen showing a read-only view of the Dataset schema, its Concepts and their property definitions:

Editing Concept properties

To edit the properties of one of the Concept in the Dataset click the Edit Schema button in the bottom corner of the Concept details pane. Note, you will not be able to modify the property of a Concept schema if Concept instances already exist for the type you are editing. You can always add more properties to a Concept definition by clicking the + icon to the right of the last property:

Adding a new Concept type to a Dataset

To add a new Concept class/type to a Dataset schema, select a new Concept type from the Add a new type drop list at the top right of the Edit Schema screen. Choose a predefined Concept type, or choose Custom to create one of your own:

You will then be presented with a form to edit the properties of your new Concept.
