Summary Object Interchange Format
SOIF

   <World-Wide Web, protocol> (SOIF) The attribute-value pair
   record format which {Harvest Brokers} use to exchange
   {Harvest} content summaries.

   SOIF provides a means of bracketing collections of summary
   objects, allowing {Harvest Brokers} to retrieve SOIF content
   summaries for many objects in a single, efficient compressed
   stream.  Harvest Brokers provide support for querying SOIF
   data using structured attribute-value queries and many other
   types of queries.
