OraCIF is a set  Pl/Sql packages running on Oracle  9.2  using  dynamic SQL. It requires DBMS_LOB, UTL_FILE, DBMS_JOB, DBMS_SESSION and XML_DB Oracle Utilities. 

The routines  created  for the  Generator are Pl/Sql    database stored procedures which handle  Sql and SqlX  cursors.   OraCIF has it's own set of Oracle tables and  uses CLOB and XMLtype Columns to store the information about mmCIF and XML documents respectively. 

Two installations of OraCIF has been done, one  for the exchange with RCSB and the other to produce  the complete set of depositions from MSD databases  in XML format to  generate the Atlas pages  for MSDlite and MSDpro. Each  installation need one dedicate  Oracle user  termed   a OraCIF instance.

For now, all XML treatment is non schema based.
