Query document schema is largely complete and is in CVS (needs docuemntation and
the operator list enumeration).

Need to continue work on message structure for the result set (RSIDS).

Added a resultset schema document (resultset.xsd) to CVS. It is an initial pass
at a structure for a result set. Still needs work, as does the query.xsd, but
both are a good basis for discussion at the meeting next week in San Diego.

Modify both query.xsd and resultset.xsd to accomodate the changes we discussed
at the meeting. This may incorporate XQuery.

To my understanding, resultset.xsd is for RISD type in queryInterface.wsdl. If
it has query itself (filter) in resultset schema, it will be very easy for
PortType decodeRISD. Because RISD already has the query part.

By the way, resultset has an element name "sendTime" and in
queryInterface3.wsdl, RISD type has an element named "timeStamp". Are they
redundant?

At the Seattle (Sept 2003) EcoGrid meeting we decided:

Revise query.xsd:
-- add repeatable returnfield element for specifying structure of return records

Revise resultset.xsd:
-- add system, namespace, modificationDate, and creationDate to each record
-- identifiers for a record are considered relative URIs, with a base value
of the "system" attribute for that metadata, where the system should
contain the GSH for an ecogrid enabled server:
so, for example, system="ecogrid://ecogrid.nceas.ucsb.edu"
identifier="/knb.1.1"
-- modify the record internal structure by creating a composite document
that contains all of the values specified in returnfield elements with
their parent elements. If the path does not reference a leaf node
text element, then all of the children of that node are returned.
For example, if the query had:
returnfield="/eml/dataset/title" and returnfield="/eml/dataset/creator"
The record would look like:

<record ...>
           <eml>
               <dataset>
                   <title>Some random title</title>
                   <creator>
                       <individualName>
                           <givenName>Matthew</givenName>
                           <surName>Jones</surName>
                       </individualName>
                   </creator>
               </dataset>
           </eml>

Initial implementation based on globus finished. Closing these bugs as we move
to a new implementation based on axis.
