NEW WEB SERVICES BASED ON-THE-FLY SMIL GENERATOR ARCHITECTURE FOR HIGHLY AVAILABLE ELEARNING PRESENTATION

Abstract

Learning objects are usually targets to transfer from one repository to another or subject to modifications due to the unavailability of the server running the repository. Synchronized Multimedia Integration Language (SMIL) has recently become increasingly important in eLearning environments to integrate learning objects into a synchronized complex multimedia web presentation. However, this standard specification lacks the ability to provide alternative links in the case of repository unavailability and may occasionally lead to broken links. An outline of various aspects of the design and implementation of web services based on-the-fly SMIL generator architecture (WSOSGA) is presented in this paper. WSOSGA consists of three tiers which cooperate together in a simple way to search for multimedia learning objects both locally and in the internet, rank them based on learning objects (LO) author considerations, generate and publish the corresponding SMIL document and its XML profile. The latter will be used by the web services tiers on the target web server to generate SMIL documents on-the-fly. The major advantage of WSOSGA is thus achieved to give SMIL presentations high availability in eLearning instructional content.
