     10Rick and I talked about on what level we should describe data: e.g., a 
     11single data set or a collection of data set. 
     12 
     13Different data archives organize their data differently. The 
     14searchable unit can be either a single FITS data set or a collection 
     15of them. 
     16 
     17One possible senario is to describe data at a level searchable by its 
     18archive, with the archive specific information encaptulated as a field 
     19in the XML meta-data desription to facilitate query 
     20translation. Alternatively, the XML meta-data description can 
     21incorporate the organizational structure of different data archives.

     47- individual data set

     54What can a data archive do?  
     55- storage 
     56- basic data search depending on database organization 
     57- data analysis? require computing resources 
     58the first two items already exist. the last item may not.

     60from the original proposal:  
     61http://sun.stanford.edu/~rick/propose/vso 
     62---------------------------------------------------------------------- 
     63data archive 
     64- geographically distributed 
     65- diversely organized 
     66- provide individually tailored access services 
     67 
     68data interoperability: translation among 
     69- data descriptions  
     70- data format 
     71-> determine the semantics of XML representation 
     72 
     73access interoperability: translation among 
     74- different search engines 
     75-> reformulate XML search into source-specific search 
     76 
     77---------------------------------------------------------------------- 
     78The NVO approach: 
     79ask some questions and see what we need to solve these problems  
     80-> identify service units, perhaps also data models.
