An HL7 v2 Platform for Standards Development and Testing

July 16, 2017
Sandra I. Martinez, Robert D. Snelick
Development of healthcare data exchange standards has long been problematic, plagued with ambiguous and inconsistent requirement specifications. This situation leads to potential misinterpretation by implementers, thus limiting the effectiveness of the

An Interoperability Test Bed for Distributed Healthcare Applications

March 24, 2014
Robert D. Snelick
Standards provide the foundation for ensuring interoperability, but if they are not implemented correctly or consistently, their value is diminished leading to problematic installations and higher costs. Conformance and Interoperability testing is

Principles for Profiling Healthcare Data Communication Standards

July 22, 2013
Robert D. Snelick
Healthcare organizations often have many proprietary heterogeneous information systems that must exchange data reliably. Seamlessly sharing information among systems is complex. The widely adopted HL7 version 2 messaging standard has helped the process of

Testing Environments for Assessing Conformance and Interoperability

July 12, 2012
Robert D. Snelick, Leonard E. Gebase
We present a classification framework of testing environments that support conformance and interoperability testing of distributed systems. We describe each testing environment and state the applicability and requirements placed on a realization of a

A Framework for Testing Distributed Healthcare Applications

July 13, 2009
Robert D. Snelick, Leonard E. Gebase, Gavin W. O'Brien
We present an architectural framework for supporting conformance and interoperability testing among distributed healthcare systems. Healthcare organizations such as hospitals employ information systems that are composed of multiple, distributed

Assessing Approaches for Evaluating Remote Heterogeneous Applications

July 13, 2009
Leonard E. Gebase, Robert D. Snelick
We examine several methods for testing disparate, heterogeneous systems that intercommunicate through message exchanges governed by a set of well defined message exchange rules. Rather than basing our assessment on a set of abstract applications, we will

Conformance Testing and Interoperability: A Case Study in Healthcare Data Exchange

July 14, 2008
Robert D. Snelick, Leonard E. Gebase, Mark Skall
Correct data exchange is critical for ensuring reliable healthcare systems. Standards based systems are the foundation for achieving this goal. However, standards alone are not enough to ensure this promise; conformance and interoperability testing are

Dynamically Generating Conformance Tests for Messaging Systems

June 26, 2006
Robert D. Snelick, Leonard E. Gebase, Sydney Henrard
The advent of XML technologies for data exchange negotiations in B2B applications is proliferating a new class of messaging standards that are only fully designed at the implementation level. These specifications offer unmatched flexibility. However, this

Selecting Effective Test Messages

June 1, 2006
Leonard E. Gebase, Roch Bertucat, Robert D. Snelick
One of the first problems that must be addressed when attempting to test the reliability of any software implementation is determining what is to be tested. The number of paths an implementation can follow is generally much too large to be able to test all

Selecting Effective Test Sets

May 26, 2006
Leonard E. Gebase, Robert D. Snelick, Roch Bertucat
One of the first problems that must be addressed when attempting to test the reliability of any software implementation is determining what is to be tested. The number of paths an implementation can follow is generally much too large to be able to test all

Studies of One-to-One Fingerprint Matching With Vendor SDK Matchers

June 24, 2004
Craig I. Watson, Charles L. Wilson, Karen Marshall, Michael D. Indovina, Robert D. Snelick
NIST has conducted testing of one-to-one SDK (Software Development Kit) based COTS fingerprint matching systems to evaluate the accuracy of one-to-one matching used in the US-VISIT program. Fingerprint matching systems from eight vendors not used in US

Multimodal Biometric Authentication Methods: A COTS Approach

December 1, 2003
Michael D. Indovina, Robert D. Snelick, Alan Mink
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometrics on a population approaching 1000 individuals. Prior studies of multimodal biometrics have been

Multimodal Biometrics: Issues in Design and Testing

November 1, 2003
Robert D. Snelick, Michael D. Indovina, James H. Yen, Alan Mink
The results of experimental studies on multimodal biometric systems for small-scale populations have shown better performance compared to single-mode biometric systems. We examine if such techniques scale to larger populations, introduce a methodology to

Implementation of an Interactive Digital TV Java Environment

January 1, 2000
Robert D. Snelick, Wayne J. Salamon, Alan Mink
The emergence of interactive digital television (DTV) brings about a host of exciting opportunities for broadcasters, content providers, tool developers, and equipment manufacturers. Interactive DTV combines aspects of traditional television and the

Using S-Check ML Version 3.0

February 1, 1998
Robert D. Snelick, N V. Drouin, John K. Antonishek, Michael D. Indovina, M M. Courson
S-Check is a tool for detecting performance bottlenecks in programs on computer systems with multiple processors. S-Check automates the techniques of Synthetic Perturbation Screening. Synthetic Perturbation Screening systematically perturbs selected
