Online education and training play critical roles in the age of Internet. For easy sharing and reusing pedagogical resources that are high-priced to develop, there are standards for encoding instructional contents and regulating their presentational formats. However, because access interfaces and message packing schemes of most e-learning resources are still proprietary, the offered contents are available to privileged users only and thus are difficult to utilize and circulate. SOAP-based Web services to some extent solve the openness issue by enforcing contents and their packing schemes conform to pre-defined formats.
