Conclusions from SSI applied in a Trust Policy Language

Since digitization means that more and more transactions in both the public and private sectors are being carried out electronically, automated processing is becoming increasingly important. However, automation requires a policy consisting of rules that define when a transaction request can be accepted. There exist already some solutions for traditional identity management concepts. However, for the decentralized identity management approach called Self-Sovereign Identity (SSI) there is no concrete implementation yet. We have closed this gap in the course of this project. Now we want to review the necessary changes resulting from the combination of Policy Language and SSI and give an outlook on future developments.
