The increasing interest in web-based learning environments stimulates researches and evidences the importance of developing technologies and standards that allow environments, instructors and participants to create, find, consume, reuse, and to share instructional contents, known as learning objects. Metadata standards, learning objects and architectures to support these technologies in Learning Management Systems (LMS) are the key for the success of e-learning. In this context, the learning object concept has essential importance and concentrates the majority of the researches accomplished in this field. At the same time, observing that the learning in the web happens through the aid of tools and learning services which are part of LMS, leads to the reflection about the current modeling and understanding of these services. This work defends the modification of the learning objects concept, extending the current one by incorporating services to its extent, being these modeled as Web Services. Finally, a framework is presented in order to facilitate the adapting of the Learning Management Systems to the new concept of learning objects, as well as a case study in the AulaNet Environment.
