scope:

This International Standard specifies an International Standard Document Link (ISDL) identifier of links between entities in the field of information and documentation. These entities may be media resources, people or more abstract items such as times or places. The ISDL identifies links between entities that are related to each other so that, for example, they can be rendered simultaneously. It does this by registering each identifier with information (metadata) that specifies the link. This International Standard does not specify the technology used to represent the identifier or realize the link. It enables applications to be built which use the interoperable ISDL system for the identification of links.
