The HIEOS XDS.b implementation has enhanced the NIST XDS.b base implementation in the following ways:

• Replaced underlying ebXML registry implementation (now native ebXML v3 vs ebXML v2)
• Replaced file system based XDS.b repository with RDBMS storage mechanism
• Incorporated Patient Identity Feed HL7 V3 transaction [support for add/update/merge transactions]
• Incorporated IHE ATNA logging support
• Ported to GlassFish ESB
• Ported to MySQL [with support for PostGres]
• Replaced internal REST calls with JDBC invocations when communicating with internal ebXML registry
• Replaced internal logger with "asynchronous" logging mechanism; also added ability to "turn off".
• Incorporated database connection pooling throughout code
• Externalized URLs, ports, and other parameters in a new XML based configuration file
• Restructured code base, removed "dead code" and stripped out test utilities within mainline web service code
• Removed proprietary Sun class usage
• Enhanced client test suite
