How will the Upload-Match pattern be handled in VOSpace/TAP/VOQL?
A principle justification of the VO itself is to encourage statistical studies of populations of
astronomical objects, as well as the more traditional single object study. One very important usage pattern is the matching of archival catalogs with a "personal catalog" supplied by the user, that may have 10, 1000, or more sources. It should be easy for a user to do this, without the need for jumping through hoops of authentication, persistent storage, asynchrony or
ADQL. These latter are necesary evils for very large numbers of sources, but should not be necessary for smaller, simpler types of matching.
