16 THE SEARCH FOR OBJECT X and the Virtual Educational Observatory

17 GENERAL CONSIDERATIONS in making EVOs from the NVO SELECTED DATA SETS, not access to the entire database, is what is requiredSELECTED DATA SETS, not access to the entire database, is what is required THE USER INTERFACE is of prime importance, and should be designed, if not created, by teachers. The advice and collaboration of the research community is essential, however.THE USER INTERFACE is of prime importance, and should be designed, if not created, by teachers. The advice and collaboration of the research community is essential, however. BOTH DATA and PROCESSING can be distributed, but servers may have to handle the onslaught of classes rather than sporadic users.BOTH DATA and PROCESSING can be distributed, but servers may have to handle the onslaught of classes rather than sporadic users.

18 WHATS NEXT FOR PROJECT CLEA ? WHATS NEXT FOR PROJECT CLEA ?
