Description

The processAssociationEvent service is responsible for processing an Association Event (DTE), issuing a Verifiable Credential (VC), uploading it to the Storage service, registering the link to the stored DTE with the Identity Resolver service. It handles the entire lifecycle of creating and managing an association event, from data input to storage and resolution.
