To quote: ([http://www.cdlib.org/inside/diglib/ark/]) |
The Archival Resource Key (ARK) identifier is a naming scheme for persistent access to digital objects (including images, texts, data sets, and finding aids), currently being tested and implemented by the California Digital Library (CDL) for collections that it manages. |
An identifier is an association between a string (a sequence of characters) and an information resource. That association is made manifest by a record (in the case of this service, a METS record ) that binds th\[e identifier string to a set of identifying resource characteristics. The ARK identifier is a specially constructed, globally unique, actionable URL. Each ARK links end-users to three things: |
- Digital object metadata
- Digital object content files
- A commitment statement made by the CDL concerning the digital object.
