BPN-DID Resolution Service

The BPN-DID Resolution Service (BDRS) provides a directory of Business Partner Numbers (BPN) and their associated DIDs. The directory is used by dataspace participant agents to resolve a DID for a BPN.

The directory is requested via a RESTFul HTTPS API and is designed to be cached locally for resolution operations. When requesting the directory, the client must include a JWT with a presentation containing its MembershipCrediential for authentication.

Implementation

The BDRS is a collection of extensions to the EDC core runtime.

Variants

There are two general variants of BDRS:

1. Production: named "bdrs-server", this distribution utilizes Postgres and Hashicorp Vault for data and secret retention. Please take a look at the helm chart README
2. Testing: named "bdrs-server-memory", this distribution uses all in-memory components to lower the barrier of entry and the need for configuration when testing against BDRS

Interacting with BDRS

BDRS comes with two APIs:

1. Management API: used to maintain directory listing entries. Should not be exposed without additional protection to the internet.
2. Directory API: clients can obtain the BPN-DID resolution mapping directory as a whole. Clients should implement a reasonable strategy to cache the directory locally. Note that a valid VerifiablePresentation in JWT format, containing a valid MembershipCredential (also JWT format) must be provided as Bearer token in the Authorization header!

Run official Helm charts

checkout the Chart README

Build and run BDRS from source

• Build sources (-x test skips the tests):

  ./gradlew build -x test

• Run with java:

  java -jar <VM-PARAMS> runtimes/bdrs-server/build/libs/bdrs-server.jar
  java -jar <VM-PARAMS> runtimes/bdrs-server/build/libs/bdrs-server-memory.jar

  Note that configuration parameters have to be supplied as VM parameters or environment variables.

• Run with Helm (recommended, assuming KinD):

  ./gradlew dockerize
  kind load docker-image bdrs-server:latest
  kind load docker-image bdrs-server-memory:latest
  
  helm install bdrs-server charts/bdrs-server \
    --set server.debug.enabled="true" \
    --set server.image.pullPolicy="Never" \
    --set server.image.tag="latest" \
    --set server.image.repository="bdrs-server" \
    -f path/to/your/values.yaml \
    --wait-for-jobs --timeout=120s --dependency-update
