Towards a consolidated model for a collaborative courseware authoring system

Abstract In an effort to reduce the expensive resource requirements in courseware production and to allow effective management of, and communication and collaboration between authors, a model is needed to harmonize the diverse theoretical backgrounds such a process requires. To this end we look at five abstract models which where chosen for their apparent appropriateness within the general area of collaborative authoring and reuse of multimedia courseware. These models consist of a functional model of hypertext, an infrastructure model for an open collaborative authoring system, two object-oriented communication models, and a courseware production model. We attempt a consolidation of these models and ultimately make several conclusions, which are exposed during a conceptual harmonisation. The principal conclusion is that a hypermedia logical model is not by itself adequate to support collaboration and reuse. Our modeling conclusions have driven the design of a system which will be implemented and tested.     

Hypermedia Support for Software Development: A Retrospective Assessment

Hypermedia technologies have been available for about a decade. Beginning with Douglas Engelbart, researchers have become interested in applying hypermedia concepts and technologies to software development. This paper assesses this symbiosis between hypermedia and software development as described by research contributions; by our count, more than one hundred articles. To date, no collection of, or guide to, this literature has been published. A number of significant contributions are classified, described, and appraised — providing a guide into what has been a rich but perhaps under-reported research area. Hypermedia has made significant contributions to software development in three primary areas: coping with massive amounts of information associated with software development projects; establishing and maintaining linkages between various types of software engineering documents; and enabling development engineers to record, document, and preserve knowledge about development thoughts, processes and rationale. These contributions may help direct the focus of future research towards building on, combining and assessing the resulting contributions. A research agenda is proposed along these lines.     

WWW环境下超媒体协同创作系统的设计

1 引言大型文献的创作是一种涉及到总编、美术、策划以及多个作者之间的协作活动,超媒体技术的出现为大型文献创作者提供了一种新的创作方式,能够很好地支持这种协作活动。常规文献是连续的线性结构,文献在组织结构上没有划分手段,因此协同写作时难以进行分工。超媒体文献的离散化节点和超链组织有利于多人协作时任务的划分,多成员可在分布环境下分担完成文献中的不同部分,通过超链可将各部分链接起来,保持整个文献的完整性。对于读者,超文本技术允许有选择地阅读其中感兴趣的部分,而忽略其他部     

基于Petri网超媒体模型研究

在分析当前超媒体形式化模型特点的基础上,本文提出了一个全新的模型－ＣＰＮＨ,它基于有色Ｐｅｔｒｉ网,具有刻画分布超媒体主要性质的能力,与其他模型相比该模型能够有效解决并发浏览、存到控制和版本总理２,而且有力刻画了分布环境下多媒体的动态特性文中着重给出了ＣＰＮＨ模型的形式化定义并举例说明。     

Automatic generation of instructional hypermedia with APHID

This research investigates the use of patterns in designing adaptable, flexible hypermedia applications. While patterns are particularly applicable to software design, they can also be used to assist designers of other types of applications. We have developed a method (APHID) that guides a hypermedia creator through the analysis and design process. The method ensures that good design principles are followed, both for the hypermedia application and for the interface that presents the hypermedia application. Our method uses a concept map, constraints, and patterns (instructional and presentation) to support partial automation for creating hypermedia applications. We also present a prototype software system that uses the APHID method to create instructional hypermedia applications semi-automatically. The applications created using APHID are tailored to specific types of learners. We conclude with a claim that this approach is applicable not just to instructional hypermedia, but to the larger problem of generating adaptable interfaces.
