                      COMCIFS CLOSED MEETING
                        9 August 1999
                          1300-1500
                        Held in Etive

1. Merging dictionaries                   McMahon, Bernstein
     As new dictionaries come on line this function is becoming
     more urgent.
     
2. Intellectual property rights                      McMahon
    Where do we stand at the moment?
    
3. Cif Browser-editor
    There is a growing need for such an application to avoid
    discouraging the users.  Where do we stand in the
    development of such browsers?  What action should we be
    taking?
    
4. Encoding and Dissemination                         Berman

5. Coordinating CIF developments with non-crystallographic data
projects (items 3 and 7b are related)                 Berman
    Several non-crystallographic databases are now being
    developed using DDL2 to ensure that they are compatible with
    mmCIFs.  How can we ensure compatibility between the Star
    files and dictionaries.
    
6. Should CIF be registered with ISO?  
     This would strengthen our claim to the standard.  Should we
     pursue this route?
     
7. The next generation of CIF.

     a. Relationship to other file structures (XML, ASM.1)
          Similar file structures are now being widely adopted. 
          What should our relationship be with these other
          standards?  Do we need to build in some compatibility
          into CIF?
          
     b. The future of DDL
          i. How many versions do we need to maintain?
             Should we move towards a single DDL?  Can we define
             a DDL3 that is compatible with DDL1 and DDL2?
          ii. Should the IUCr assume ownership of the DDL's we   
              use?  (See items 5)
          iii. Additional functionality
                 1. Type constructs
                 2. Multidimensional arrays
                 3. Nested loops
                 4. Save frames
                 5. Methods
