USEWhat it is used for

Representative use cases for the Reconciliation service domain within a BIAN-aligned core-banking landscape.

APIBIAN semantic API

The control record (Reconciliation Case Procedure) is exposed through uniform BIAN action terms. Java 21 · Spring Boot 3, OpenAPI at /swagger-ui.html, health at /actuator/health.

RUNRun it yourself

Each service domain is its own standalone Spring Boot repository — clone and run in seconds, or deploy onto Kubernetes with the bundled Helm chart behind the Cilium mesh.

# run this service domain standalone
git clone https://github.com/Sreenivas-Sadhu-Prabhakara/sd-reconciliation
mvn -f sd-reconciliation spring-boot:run
curl localhost:8080/v1/service-domain

# or deploy onto Kubernetes (Cilium eBPF mesh)
helm upgrade --install sd-reconciliation ./helm -n bian-operations

FAQQuestions

What is the BIAN “Process” functional pattern?
A Process service domain executes and tracks a defined operational procedure, step by step, to completion. Reconciliation applies it to the Reconciliation Case.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Reconciliation is the service domain for Operations; it manages the Reconciliation Case Procedure and exposes it through standard BIAN action terms.
What business area does Reconciliation belong to?
Reconciliation sits in the Operations and Execution business area — the operational core that executes payments, positions, settlements and transactions. It runs in the bian-operations namespace as one independent Spring Boot microservice.
Is Reconciliation production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
