DOI
“The DOI (Digital Object Identifier) is an international standard (ISO 26324) managed by the International DOI Foundation, which provides a system to support persistent identification of content objects and related entities in digital networks.”
“You do not have to be a member of the DOI Foundation in order to assign DOI names but you do need to be affiliated with a Registration Agency in some way. DOIs are, and will always be, free to resolve. A DOI can apply to any form of intellectual property expressed in any digital environment. An entity can be identified at any arbitrary level of granularity. This means that, for instance, DOIs can identify a journal, an individual issue of a journal, an individual article in the journal, or a single table in that article”
