Note on access policy

When the project will be completed, a hierarchy of access to the database will be provided.

• level1: Model Building. Access is reserved to the team responsible for the model construction. At this level, the database structure is implemented, the geometrical part of the model is edited, the information necessary for the projection of the images on the model is computed and the basic elements (stones in our case) are defined. Some operations can be done trough the intranet, others need to be done from the server where the database is stored.
• level2: Model Querying. Access is reserved to the people managing the cathedral (manager, architect, clerck of the work, conservators...). It provides a reading access to the database and gives some possibility of editing (create and edit new themes). Access is provided through the internet, via PHP interfaces. This level is still in an experimental stage.
• level3: General Information At this level, information about the aims and developments of the project is offered to the general public and interested researchers. This level is already partially implemented. It will contain documents presenting the project, a reduced database of images and examples of output (require a vrml plugin).
