FAQQuestions

What is the BIAN “Manage” functional pattern?
A Manage service domain plans, coordinates and oversees a resource or activity across its lifecycle. Open Item Management applies it to the Open Item.
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. Open Item Management is the service domain for Operations; it manages the Open Item Management Plan and exposes it through standard BIAN action terms.
What business area does Open Item Management belong to?
Open Item Management 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 Open Item Management 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.
