Several hypermedia data models have been proposed in order to face hypermedia as a paradigm to develop information-oriented systems. However, hypermedia modeling introduces very specific requirements not found within conventional database modeling due to several issues must be considered during a design effort, such as modeling of data navigation, data perception, and human-machine interaction.
... [Show full abstract] Most of present data models oriented to hypermedia present differences on abstraction level, modeling issues, and considered data aspects. An Abstract Categorization Map is proposed as a graphical tool through which it is possible to assess and compare existing specification mechanisms of data models oriented to hypermedia. The map allows an analysis of existing models as an exercise to relate them and therefore derive strengths, weaknesses, overlaps, or omissions. It also allows observing existing gaps between the modeling of data considering different levels of abstraction ¦ .
