title: FIREBIRD BLR DECODER
body: <p>folks. When i belived i was a genius and that metadata was my intelectual property, i developed a procedure  in firebird to track changes on a single table, something with id´s and time stamps. So, i´ve done a mega clever move and deleted the source of this procedure. </p>
  
  <p>Does anyone knows a BLR decoder, or the doc´s that i need to build one?</p>
  
  <p>TIA.</p>
