FAQQuestions

What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. Knowledge Exchange applies it to the Knowledge Article.
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. Knowledge Exchange is the service domain for Corporate Services; it manages the Knowledge Article Operating Session and exposes it through standard BIAN action terms.
What business area does Knowledge Exchange belong to?
Knowledge Exchange sits in the Business Support business area — the shared corporate, finance and technology domains that run the bank itself. It runs in the bian-business-support namespace as one independent Spring Boot microservice.
Is Knowledge Exchange 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.
