The Digital Item Declaration Language (MPEG-21 DIDL) developed by the Moving Picture Expert Group is a generic XML format consisting of 'items' that support a modulair structure. Every 'item' contains its own descriptions of the object ('descriptors') and the object or reference tot the object that represents the item ('components').

According to the MPEG21 DIDL Application Profile for Institutional Repositories a DIDL container contains a single top-level item that may be viewed upon as the conceptual publication as a compound object. This compound object then consists out of at least one item containing bibliographic metadata and zero or more item containing (references to) objects. These objects may be PDF documents inside the repository, but also relevant links to other websites or pieces of XML. In addition to these objects, according to the specification a reference may be made to a so-called Jump-off page. This is a HTML webpage at the repository which serves as a human readable startingpoint in getting access to (descriptive) information. An example of such a jumpo-off page can be found on http://hdl.handle.net/1765/19960.
