The demands on a universal object format are described based on a processing schema from  DIAS-Core. The object is processed as a Submission Information Package (SIP) and delivered as a Dissemination Information Package (DIP) (using the OAIS model terminology).

Within the DIAS-Core, a part of the data, the Archival Information Package (AIP), is separated and put into storage (hard drive, magnetic tape, etc.). Specific metadata are stored in a data management database, which can be accessed via an administrative interface.

Detailed information about kopal's universal object format can be found in the following reports:
