LHM: a logic-based hypertext data model for integrating hypertext and information systems

The work employs logic modeling as a common language to integrate two independent information domains-document management and hypertext. The paper extends the authors´ previous work by introducing the concept of composite objects to the logic model (J. Wan et al., 1994). Allowing high level descriptions of both the hypertext and application domains greatly extends the expressive power of these models, as well as the logical bridge laws that map application elements to hypertext elements
