Specific representations may be agreed to meet special technical requirements. For example, the joint ANSI / Society of Cable and Telecommunications Engineers standard "Digital Program Insertion Cueing Message for Cable" (SCTE 35:2013) defines (among other things) the standard method for cable TV systems to include EIDR DOI names in-band with the programs being broadcast. It uses a compact lossless EIDR representation rather than the full ASCII DOI string. This also makes use of the resolvability of DOI names, suggesting that IDs so carried can be resolved via an out-of-band mechanism to collect more data.

DOI names may also be presented in a shortened version via the shortDOI service: see ShortDOI Service.
