David W. Flater (Fed)

Computer Scientist

Dr. Flater is a Computer Scientist with the Software and Systems Division of the Information Technology Laboratory at the US National Institute of Standards and Technology.  His current research focus is software metrology—helping physical scientists and computer scientists understand one another a little bit better so that metrology (the science of measurement) and science generally (the system of human knowledge) will be more cohesive across disciplines.

Dr. Flater's previous works have covered interoperability, semantics, conceptual integrity, and conceptual modelling.  His software portfolio includes the NIST SQL conformance test suite, bootBCa, Chrome Reaper, and Votetest.  He has worked with ANSI X3H2, OMG, the CCU, and the TGDC on various standards.
