【国外标准】 Information technology - SGML applications - Topic maps

NOTE 1 This clause defines the scope of this International Standard. It should not be confused with the concept of “scope” defined in 3.16, which only applies in the context of topic maps. Topic maps enable multiple, concurrent views of sets of information objects. The structural nature of these views is unconstrained; they may reflect an object oriented approach, or they may be relational, hierarchical, ordered, unordered, or any combination of the foregoing. Moreover, an unlimited number of topic maps may be overlaid on a given set of information resources.
