An IMS LD Graphic Editor using the graphs representation for modifying the course structures

We developed a Web portal, named netUniversité, that enables the teachers to create their courses online then to visualize, manage and participate to them. In order to create and execute the courses content, we have implemented an IMS LD player and an IMS LD web course content editor. These modules are integrated in the netUniversité. Using this application the teacher can automatically generate educational Web site structures, adding the pedagogical contents in these structures. However, the main weakness of a web editor (like ours) is the lack of a global view of course structure. These aspects prompted us to create a graphical editor that offers to the teacher a perspective on the IMS LD document with the possibility to perform some basic editing operations (adding, moving, deleting) in order to complete the web editor. In this paper we describe our approach concerning this graphical editor that is included in the web editor to the netUniversité web portal.
