David Jordan founded Object Identity, Inc. in 2001 to provide JDO consulting services. He became interested in the integration of object type systems and databases while earning his M.S. in Computer Science in the early 1980s. At Bell Labs in 1985, he initiated the development of the first C++ object database. He has developed a variety of applications using C++ object models on top of network, relational, and object database systems. Bell Labs appointed him a Distinguished Member of Technical Staff in 1990 for his contributions in object and database technologies. The Object Data Management Group (ODMG) asked him to serve as their C++ editor in 1993. He served in that role until 2000 and was appointed their Java editor in 1998. He coedited four books published by the ODMG. David served as a C++ Report columnist describing the ODMG standard from 1994 to 1996, at which point he stopped to write his first book, C++ Object Databases. David started using Java in late 1995. Upon his selection as ODMG's Java editor, he became a columnist for Java Report, initially covering ODMG and then JDO. David was part of the small group that initiated JSR-12, and he became one of the initial members of the JDO expert group. The JDO specification has a special acknowledgment of David's contributions to the JDO standard. When the JDOcentral.com community web site was formed, David was selected to serve as its moderator.

Craig Russell studied applied mathematics at Harvard University (B.A. '70 - '71) and acquired practical experience working as a technician repairing mainframes with the computing power of a 1997 model laptop. His early experiences in distributed computing included building applications with CICS and DL/I and designing heterogeneous network server implementations for file, print, and communications sharing among personal computers. Craig later dealt with issues of persistent object interoperability among Smalltalk, C++, and Java and integrating object and relational databases using X/OPEN XA protocols and commercial transaction processing systems. Craig served as the Java Chair of the Object Data Management Group and played a key role in the development of the ODMG 3.0 Java binding. For the next standard for database access from Java, the ODMG decided to support the Java Community Process as the delivery vehicle. With support from all major relational database and middleware vendors, Java Specification Request 12, Java Data Objects, was proposed in May 1999 and released in April 2002. Concurrent with the development of the JDO standard, Craig's primary responsibility was to lead the implementation of the object-relational database engine for several Sun products, including Java Blend and Forte for Java Transparent Persistence. Craig currently is the architect for the Container Managed Persistence implementation of Sun ONE Application Server, where he deals with the reality of implementing the high-performance, specification-compliant version of the object-relational database component of the J2EE application server.
