Create and import Schemas


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.
