The Digital Object Identifier (DOI) system is ubiquitous in research or other published documents. Documents are assigned a unique identifier - a DOI - to enable long term retrievability and support communication.

But how are DOIs created? And how much does production cost? Why do they always start with “10.”? What software is used to actually achieve the massive scale and handle the high availability requirements? What are some unusual or special applications of DOIs? How do DOIs relate to others ids?
