November 2003 InterLab Juli Hearn Savannah River Site We-SHARE Web-based Electronic Sharing and Reallocation of Assets

We-SHARE Overview Web-based application Tool for DOE Complex hosted by SRS or available for individual site deployment Identify materials and equipment for exchange to maximize the use of Government assets Utilizes open-source, non-proprietary, inexpensive systems and software Simple Powerful

We-Share Development Concept based on SRS internal version used by Property Management  Oracle and Oracle Forms Two deployment options  SRS host for complex  Distribute to individual sites for own deployment Mid 2001 re-written for external use to limit the implementation requirements Implemented as a stand-alone application – independent

We-Share Development (cont.) Challenges  Keeping simplicity to work within parameters of diverse platforms and systems complex wide  Powerful enough to be useful  Data storage – independent from individual sites’ storage methods  Security  User Interface – new vs. experienced user

We-Share Development (cont.) Software/Environment/Tools Used  Apache Web server with JServ  Java 2 v1.3  Servlets  Java Classes JDBM – Java Database Manager Prepared Text

We-Share Development (cont.) Innovations  JDBM – Java Database Management Modeled after Unix DBM Hash Table file Written in Java  Prepared Text Uses Java classes to marry data derived by JDBM with a prepared text file (style sheet) for display XML approach without XML

Deployment System/environment  Windows vs. Unix differences Access and usage  Controlled through IP list Technical Transfer  Knolls Atomic Power Lab (KAPL)

Demonstration

Future Plans Server upgrade to Java 2 v1.4  Elimination of Cocoon use Re-write to utilize XML (based on user community needs) Implement use of application complex-wide Additional tech-transfer distribution to other sites

Conclusion DOE complex-wide tool to maximize the use of government resources Utilizes open-source, non-proprietary, inexpensive systems and software  Java technology – servlets and classes  Packaged, Web-based application Limited implementation requirements  Java 2 only environment requirement Simple Powerful
