The Aristotle Approach to Open Hypermedia
نویسندگان
چکیده
Large-scale distributed hypermedia systems comprise a generation of powerful tools to meet the demands of the new information globalization era. The most promising of such systems have characteristics that allow for the easy adaptation both to an, actually, unpredictable technological evolution and to the constantly evolving information needs of users. Such systems are generally known as Open Hypermedia Systems (OHS). Recently, research effort has been focused on the formulation of a solid set of OHS standards (i.e., protocols, reference models and architectures) that would stem from a common understanding and thus, direct future implementations. Unfortunately, sophisticated hypermedia notions like composite nodes and dynamic linking, still found in older, monolithic hypermedia systems, have been overlooked or roughly portrayed. This paper presents a distributed system architecture implemented on top of a hypermedia model for OHS, which captures notions like these and sets the foundation for straightforward implementations. The proposed hypermedia model comprises a Hypermedia Data Model, which is extensible and fulfils a series of OHS requirements, and a Structural Model, which ensures controlled hyperdocument construction and flexible dynamic linking. Aspects of a prototype hypermedia server (Aristotle), which has been the testbed for this architecture, are discussed.

Transoral Resection of Giant Parapharyngeal Space Tumors via a Combined Surgical Approach
Introduction: Parapharyngeal space (PPS) tumors account for 0.5% of the head and neck neoplasms. Based on the evidence, 80% of these tumors are of a benign nature. Surgical excision is the treatment of choice for this condition. The present study was conducted to propose transoral resection as an efficient way to excise the benign well-defined tumors of the PPS. Materials and Methods: Thi...
متن کاملScripting Facilities in Open Hypermedia: Experiences from the Webvise Open Hypermedia System
This paper discusses an approach to scripting in open hypermedia systems. The approach is based on an embedded interpreter that enables scripts to communicate with the hypermedia engine as well as external applications in an open way. The design and implementation of the scripting facilities in the Webvise open hypermedia system exemplify this approach. In Webvise, scripting is closely connecte...
متن کاملExtending User-Interface Toolkits with Hypermedia Functionality
This paper1 describes a technique for extending user-interface toolkits with hypermedia functionality. The technique employs a separation-of-concerns approach which is incremental, reusable, and maintainable. The essence of the approach is to integrate a user-interface toolkit with an open hypermedia system. The integration occurs through a set of integrated widgets and a hypermedia infrastruct...

متن کاملLogic-Based Open Hypermedia for the Semantic Web
A challenge of the semantic web is provision of distributed information with well defined meaning, understandable for different parties. The aim of open hypermedia research has been to support such understanding on hypertext structures since several years. In this paper we show how the semantic web resource description formats can be utilized for automatic generation of hypertext structures fro...
