A DOI name - a digital identifier for any object of intellectual property. A DOI name provides a means of persistently identifying a piece of intellectual property on a digital network and associating it with related current data in a structured extensible way. A DOI name can apply to any form of intellectual property expressed in any digital environment.

The DOI Data Model comprises an interoperable structured data dictionary: the indecs Data dictionary (iDD) and a framework for applying it.

The IDF finances all the central, communal infrastructure and architecture work described in the DOI Handbook and fact sheets on our web site. The entry price we ask for using that work in collaboration with us is that interested parties become a member of the IDF or work with an existing member. As a member, you can get a DOI name prefix for experimental purposes: we require that this will be limited in use and not used in a production environment.
