A Brief History of the LREETB: Dublin Core, NNTP => LRE Thesaurus CELEBRATE: LOM, Brokerage System (JMS +
WS) => Simple Query Interface (SQI) + LRE Application Profile (LRE AP)
FIRE: LOM, SQI Brokerage System => S2QLCALIBRATE: LRE AP, SQI + OAI-PMH Brokerage
System, S2QL => PLQL MELT: Service-Oriented Architecture => >150,000
