The integration of SQI in a reusable learning objects system: Advantages and disadvantages

Abstract:

Current e-learning applications should provide universal access to educational information, regardless of the standards, protocols or programming languages used. This would maximize the reuse of learning objects and help this technology to gain its place as a fundamental and, in some cases only, support tool for present day educational systems. To achieve this, it is necessary that standards are adopted that guarantee, both the development of learning objects and the search systems that provide access to the repositories that contain them; this being the only way to guarantee universal access. In this article the effects produced by one of the standards attempting to guarantee universal access are studied. The main features of the principal systems that execute it are identified, as well as its more notable advantages and disadvantages. The integration of the SQI (Simple Query Interface) standard in a reusable learning objects system, previously developed by the authors, is put forward, describing the conclusions of the process. © 2008 ACM.
