HDM—a model-based approach to hypertext application design

Abstract

Hypertext development should benefit from a systematic, structured development, especially in the case of large and complex applications. A structured approach to hypertext development suggests the notion of authoring-in-the-large . Authoring-in-the-large allows the description of overall classes of information elements and navigational structures of complex applications without much concern with implementation details, and in a system-independent manner. The paper presents HDM (Hypertext Design Model), a first step towards defining a general purpose model for authoring-in-the-large. Some of the most innovative features of HDM are: the notion of perspective ; the identification of different categories of links (structural links, application links, and perspective links) with different representational roles; the distinction between hyperbase and access structures ; and the possibility of easily integrating the structure of a hypertext application with its browsing semantics. HDM can be used in different manners: as a modeling device or as an implementation device. As a modeling device, it supports producing high level specifications of existing or to-be-developed applications. As an implementation device, it is the basis for designing tools that directly support application development. One of the central advantages of HDM in the design and practical construction of hypertext applications is that the definition of a significant number of links can be derived automatically from a conceptual-design level description. Examples of usage of HDM are also included.

Toward a Framework for Semantic Organizational Information Portal

“…-Hypertext Architectures and, in particular, the WWW conceptual models such as WebML [2], W2000 [3], HDM [4], OOHDM [5], Araneus [6], and WSDM [7], that are proposals for the conceptual specification and automatic implementation of Web sites. -Ontologies, to model the domain information space, the navigation, the access, the presentation and possibly even the operation offered by a portal.…”

“…We surveyed various model-driven approaches to design Web applications available in WWW conceptual model literature [2][3][4][5][6][7]. They show it is possible, and even convenient, to model separately at least the domain information space, the navigation, the access and sometimes also the operations.…”

“…In order to design the domain information model WWWCM approaches use existing modeling languages: E-R diagrams in HDM [4], UML class diagrams in W2000 [3] and OOHDM [5], etc. Moreover, they explicitly provide a set of adhoc primitives to model navigation (e.g.…”

Techniques and Methodologies for Multimedia Systems Development: A Survey of Industrial Practice

“…Hypertext Design Model (HDM) Garzotto et al (1993) Relationship Management Methodology (RMM) Isakowitz et al (1995) Object-Oriented Hypermedia Design Methodology (OOHDM) Schwabe & Rossi (1995) World Wide Web Design Technique (W3DT / SHDT / eW3DT) Bichler & Nusser (1996) Attitudes Towards Methodology Usage When asked about the advantages or benefits of their principal methodology, the response from both samples (aggregated in Table 3) highlights cost effectiveness (74%), speed of development (63%), understandability (58%) and adaptability (53%) as the most important ones. The relative weight given by respondents to benefits that emphasize improved efficiencies in cost and speed suggests an inclination to use methodologies that assist project management.…”

Web-Based Information Systems—Innovation or Re-Spun Emperor’s Clothing?

“…Many innovative methods have been put forward by academics (Garzotto, Paolini and Schwabe, 1993;Isakowitz, Stohr and Balasubramanian, 1995;Gellersen, Wicke and Gaedke, 1997) but research indicates that practitioners are not making use of them (Barry and Lang, 2001). Should the IS community be alarmed at this?…”
