The DIP format is the last in sequence of the three IP formats defined in the OAIS reference model. As with the two others, the SIP and the AIP format, the E-ARK DIP builds upon the same foundation - the Common Specification for Information Packages.
The definition of an E-ARK DIP is led by practical access considerations: a DIP is an Information Package which is ready to be processed by its designated Access Software; if it is not suited for processing and rendering by its designated Access Software, it is not (yet) a DIP.
In order to meet the stated access scope, much of the specification deals with scenario descriptions that are associated with specific Content Information Types (Databases, Data warehouses, Electronic Records Managements Systems, Simple File-System Based Records, and Geodata).
This document is structured according to the specifications and access scenarios of the five aforementioned content information types. This structure has the advantage that each content information type section can stand alone. The drawback is that there are repetitions in each section.
