A Service Versioning Model for Personalized E-Learning System
Service Versioning is a hot topic that has generated a broad range of guidance from a variety of sources. Several Web services standardization efforts are underway but none of them address the problem of service versioning. Service versioning with metadata in e-learning system makes easy search, retrieval, import and evaluate. In e-learning systems, learning objects with metadata allow the learners to use quality educational contents filling their characteristic and teacher may use quality educational contents to structure their courses. A service versioning model in e-learning objects system with metadata satisfies the requirements for learning environment. In personalized e-learning systems, when more numbers of learner searching data the retrieval time is being delayed when the data volume is increasing continuously.
