ORS is short for Open Resource Sharing

ORS is:

• an Interlibrary loan (ILL) backend
• the backend for the ILL part of library.dk (in danish: bibliotek.dk)
• currently handling 30 000 orders each week
• robust -- designed as a statemachine to provide guarantees in the event of errors or failing components
• scalable -- designed as a distributed system with build-in load balancing
• partly implemented in c++ (the infrastructure to handle tasks and orders)
• partly implemented in javascript (business logic to transform tasks and orders)
