Abstract

Courseware systems are often based on an assembly of different components, addressing the different needs of storage and delivery functionality. The Learning Technology Standard Architecture LTSA provides a generic architectural framework for these systems. Recent developments in Web technology – e.g. the Web services framework – have greatly enhanced the flexible and interoperable implementation of courseware architectures. We argue that in order to make the Web services philosophy work, two enhancements to the LTSA approach are required. Firstly, a combination with metadata annotation is needed to support the discovery of educational Web services. Secondly, if these components are to be provided in form of services, more support is needed for their assembly. Architectural patterns of a finer degree of granularity shall satisfy this need.
