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

+
+What can a data archive do? 
+- storage
+- basic data search depending on database organization
+- data analysis? require computing resources
+the first two items already exist. the last item may not.
+
+from the original proposal: 
+http://sun.stanford.edu/~rick/propose/vso
+----------------------------------------------------------------------
+data archive
+- geographically distributed
+- diversely organized
+- provide individually tailored access services
+
+data interoperability: translation among
+- data descriptions 
+- data format
+-> determine the semantics of XML representation
+
+access interoperability: translation among
+- different search engines
+-> reformulate XML search into source-specific search
+
+----------------------------------------------------------------------
+The NVO approach:
+ask some questions and see what we need to solve these problems 
+-> identify service units, perhaps also data models.
