   High,

   The PSI mail system is ill in the moment, I'am not sure if I got all
   messages in the NAPI-list. But I comment on those I got:

   - I agree with Jon about Occams Razor.Let us stick as much to HDF 
     standards as possible. The only reasonable change I can think of
     is to use vGroup attributes instead of those SDS's with text data.

   - file_time: was in my notion the creation date of the file, there is 
     another time with each entry which jots down when the entry was written.
   - file_name: the reason to put it in was that it should be recognizable
     what the initial file name of the thing was before a user renamed it
     and dir other mean things to it. Could be useful.
   - Do not worry to much about those old PSI files. It mainly concerns 
     one instrument, the powdwer diffractometer DMC. We had test runs only
     last year. So no massive amounts of files have been transferred from
     PSI to everywhere else. I supplied these files as examples and we may
     need to tell some people about these issues. I'll make sure that the
     new data files we write when starting up at June 29 (scheduled) use
     only NX_CHAR for text. 

                                     Regards,
                                                  Mark
