The document discusses the challenges of handling a large volume of DOI registrations from multiple sources at Wiley publishing. It outlines five principles used in the XIRS system to manage this workflow: 1) Centralization through a single system, 2) Transparency through monitoring and reporting, 3) Self-healing through queuing and backup methods, 4) Validating data by assuming errors and 5) Synchronous communication to avoid lost responses. XIRS was built to centralize DOI registration for Wiley and apply these principles of managing high volumes of content from different locations.
