Create and import Schemas

Introduction:

Schemas are the sum of all attributes of a credential. Example: The schema of the German personalausweis (eID) consists of 13 attributes. Once created / written to the network all issuers can use the schema to create their own credential definition.

You can import an existing schema by reviewing existing schemas, which have already been written to the IDunion (Test) Network or take a look out our pre-defined schemas.
You can also create new schemas within the Lissi Agent.

Step 1: Create a new SCHEMA by press the “+” button

Step 2: Select “New Schema”

Step 3: Enter a name for the schema (e.g. EmployeeID)

The name will be written to the ledger and displayed in your Lissi agent.

Step 4: Set a version number (e.g. 1.0)

The version number will be written to the ledger.

Step 5: Select a picture (.png file) which will later be displayed as a tile in the Agent
