Linking Mechanisms The Digital Object Identifier (DOI): is a unique “dumb number” assigned to an entity remains persistent for the life of the digital object is comprised of a prefix and a suffix separated by a forward slash One or more prefix per content producer The suffix can be any type of identifier The suffix can be assigned to entities of any size or granularity or any file type Getting Technical - Linking UKSG SRM – Introduction November 2002
Linking Mechanisms The DOI is analogous to the Universal Product Code (UPC) bar code But… the DOI is not equivalent to a Universal Resource Locator (URL) A URL points to the location (to an instance) of content. Whereas a DOI permanently names that CONTENT and facilitates retrieving multiple instances of it, or of other associated information Getting Technical - Linking UKSG SRM – Introduction November 2002
