Configuration

Flow Manager Service​

The application includes by default two flow manager services with a basic configuration, one used as the main flow and the other one as the sub flow. To complete the configuration is needed to:

  1. customize the steps and the configuration file for the main flow
  2. customize the steps and the configuration file for the sub flow
  3. add and customize new flow manager services to includes new sub flows, in particular:
    • create a new flow manager service from the marketplace
    • edit the configuration file to define the steps of the processes
    • define a new CRUD collection to collect the data related to the new process

Flow Manager Router​

The flow manager router manages the communication between external services and the set of sub flows. The plugin comes in the application with only one default rule that holds information about the used identification process, but it is possible to add more rules in order to add more identification processes to the application.

Identification Provider Adapter​

With the Application service adapter template it is possible to quickly implement a new integration for a custom identification service.

In general, the resulting microservice needs to expose an interface compatible with the flow manager service and provide a correct mapping of the extracted data as described in the previous section.

Verifiable Credential​

Usually, at the end of an identification process a document that certificate the identification is produced. It is possible to use the verifiable credentials generator template in order to speed up the implementation of your custom solution to create the verifiable credential.

Communication Modes​

The services defined in the application can communicate relying on REST or KAFKA. Switching from a mode to another is simple:

  • change the COMMUNICATION_MODE public variable value to REST or KAFKA,
  • change the FLOW_MANAGER_CONFIG_PATH public variable value to the path of the file holding the Flow Manager configurations with the REST/Kafka communication protocols. Default values are
    • /sagaConfiguration/rest.json
    • /sagaConfiguration/kafka.json

Kafka Topics​

Here we provide a suggestion for topic management:

  • two topics for the flow manager router
  • one topic for the verifiable credential
  • one topic for the main flow
  • one topic for each sub flow
