2.2 Structuring
The first part of this paper deals with a state of theชart study done to highlight the benefits of the VRE that we pro- pose. We underline the increasing role and the needs of computer science in context of Cultural Heritage data management, our reflection being divided in four main parts: Databases, Geographical Information Systems, Visualization and Communication. These parts represent the main domains of application of computer science in Cultural Heritage, par ticularlyarchaeology. We quote some theoretical as pects of documentary representation, to make clear how we have conceived the user interfaces of the Web Information System The second part concerns the development of the VRE for archaeology. Firstly, we explain the architecture of the system and the conceptual data model. Then, we show the way the corded data are retrievable and updatable, notably through the interactive maps and 3D models. Finally, we give some details about the generation of original models and graphs from the initial data.
