The Gala Framework: Version Support in Web Based Open Hypermedia
نویسندگان
چکیده
The GAIA framework prototype, described herein, explores the possibilities and problems that arise when combining versioning and open hypermedia paradigms. It will be argued that it by adding versioning as a separate service in the hypermedia architecture – is possible to build consistent versioning of both documents and hyperstructure. This approach eases some of the problems inherent in separating versioning of documents and structure and even allows versioning to be added to domains that would otherwise be unversioned. A brief introduction is given to research results in the hypermedia versioning field and GAIA is compared with previous attempts at defining hypermedia versioning frameworks. GAIA is capable of multi-level versioning and versioning of structures and supports freezing mechanisms for both documents and hyperstructure. The experiences from GAIA provide an input to new reference architectures for future versioned hypermedia frameworks.

In this paper we present a preliminary theoretical framework for the design and implementation of instructional applications for dynamic processes. These applications can be used e.g. to support the simulatorbased education. The framework is partly based on previous research on intelligent computer-aided instruction (ICAI), intelligent tutoring systems (ITS), electronic performance support syst...
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...
متن کاملAn Architecture for integrating Adaptive Hypermedia Services with Open Learning Environments
Adaptive Hypermedia Systems are capable of delivering personalized learning content to learners across the WWW. Learning Environments provide interfaces and support services to aid tutors in course construction and aid learners in navigating those courses. However, most Learning Environments deliver content sourced from local repositories. This content tends not to offer adaptive features that ...
