Paper Abstract:	Learning objects have been used in e-learning with the objective of allowing reuse content material. However, this approach also demands getting the right pieces of content and assembling them together in order to build a semantically richer instructional material. In order to guide this combination of the right content, it is necessary to define sequences of topics to be covered and then the files to be used as learning objects. In this paper we discuss Learning Object composition and sequencing from suggestions taken from Knowledge Domain Modeling. We propose the use of a domain ontology for allowing the suggestion of sequences of topics to be covered, which is also based on some concepts of Semiotics and Linguistics applied to multimedia narrative structures. Learning environment and the teacher action is represented as an enactment where educational resources have a role similar to actors in a play. So, the unfolding of a lesson is conceived as a narrative, like storytelling, so that the elements are assembled in a discourse. A representation of the Knowledge Domain is coined as ontology represented by means of OWL DL and the relevant concepts are arranged in a list extracted from the representative graph of the domain. From this list of topics, the user can chose the most adequate corresponding learning objects to be used in a class or learning scenario. The proposal was validated with domain specialists and the results are also discussed
