Mottier - September 2000 Page 3 Registration and archiving (1) Two possible ways: 1It is done by the firm, using the Web interface of CDD 2It is done at CERN. The firms supplies the drawing files on a CD The Web is suitable if:  The firm has a fast Web connection  Strict confidentiality is not required It needs registration of the firm as a CDD user and training of one operator
