Abstract
AbstractThis paper is focused on the use of Web services for the modeling and provision of learning environments in Educational Modeling Languages (EMLs). EMLs have been proposed to support the modeling of ’Units of Learning’ (e.g. a course, a lesson, a lab practice). Such modeling involves the specification of the actors (e.g. learners, tutors), the data used, the required applications and services, the tasks to be performed and the process in which all these entities are arranged. An important part of this modeling comprises learning environments where existing services and applications are intended to be integrated. This paper is concerned with the application of Web services ideas and specifications to satisfy the requirements involved in such modeling. In addition, several management issues related with Web services are considered that enable to separate the applications and services used from the control and coordination required to interact with them.
