How to get a DOI for your data or publication
What is a DOI?
A Digital Object Identifier (DOI) is a permanent online identifier for a digital asset; perhaps a journal article or a supplementary data set for a publication.
What is special about the DOI, is that while the digital object may physically move from one server to another, the link will never break. This is guaranteed by the maintenance of database that links known assets to their physical locations. This service is provided as a partnership between the publisher of the digital asset and the DOI resolving service (e.g. http://dx.doi.org/).

The anatomy of a DOI:
- DOI: Digital Object Identifier*
- ARK: Archival Resource Key*
- Object: a digital resource (can also be a collection of digital resources)
* Note that both the ARK and the DOI serve the same purpose.
