A VVSG-derived model of election data

August 26, 2009
Author(s)
David W. Flater
An effort to define a common data format for voting systems should begin with a data model that specifies the relevant concepts. To accelerate adoption and minimize conflicts, such a model should define the smallest set of concepts needed by the desired

Rendering UML Activity Diagrams as Human-Readable Text

July 13, 2009
Author(s)
David W. Flater, Philippe A. Martin, Michelle L. Crane
We describe a modification of the Petri Net Linear Form notation to support the rendering of Unified Modeling Language (UML) Activity Diagrams as human-readable text. This new notation, called the Activity Diagram Linear Form, allows UML Activity Diagrams

Relativity of Explicit Conceptual Models

August 1, 2004
Author(s)
David W. Flater
Explicit conceptual models are supposed to capture knowledge of lasting value in a reusable form. Reuse of explicit conceptual models is hampered by arbitrary and application-specific constraints; any constraints that conflict with a new application must

The AMIS Approach to Systems Integration: An Overview

May 1, 2004
Author(s)
Donald E. Libes, Edward J. Barkmeyer Jr., Peter O. Denno, David Flater, Michelle P. Steves, Evan K. Wallace, Allison Barnard Feeney
This paper is an overview of the AMIS (Automated Methods for Integrating Systems) project approach to systems integration. The objective of the AMIS project is to reduce the cost and time for software integration by devising methods, algorithms, and tools

Automated Composition of Conversion Software

March 1, 2004
Author(s)
David W. Flater
Given a library of converters with known behaviors, an integration engine must determine which are useful in a given scenario and produce a plan for how they can be used to achieve specified goals. This report documents the algorithm implemented by the

The Challenges of Automated Methods for Integrating Systems

January 1, 2004
Author(s)
Donald E. Libes, David Flater, Evan K. Wallace, Michelle P. Steves, Allison Barnard Feeney, Edward J. Barkmeyer Jr.
Automated methods for integrating systems (AMIS) have been presented as a new approach to solving the dilemmas of multiple and uncoordinated standards, ontologies, legacy systems and the ever-growing cost of traditional integration. This paper explores the

A Logical Model of Conceptual Integrity in Data Integration

August 1, 2003
Author(s)
David W. Flater
Conceptual integrity is required for the result of data integration to be cohesive and sensible. Compromised conceptual integrity results in semantic faults, which are commonly blamed for latent integration bugs. A logical model of conceptual integrity in

Concepts for Automating Systems Integration

February 1, 2003
Author(s)
Edward J. Barkmeyer Jr., Allison Barnard Feeney, Peter O. Denno, David W. Flater, Donald E. Libes, Michelle P. Steves, Evan K. Wallace
The problem of software systems integration getting independently developed software components to communicate in order to support a business application has been altered by the introduction of new software technologies, but by no means eliminated. NIST

Finding Similar Classes with a Simplified Metamodel

February 1, 2003
Author(s)
David W. Flater
To integrate conceptual models and other types of models, it is necessary to identify the portions of the models that overlap (i.e.,find similar classes) and resolve any conflicts. Complete automation of this task is generally considered infeasible

Sumo2loom Documentation

February 1, 2003
Author(s)
David W. Flater
In 2002, a project at the U.S. National Institute of Standards and Technology (NIST) called for the use of an upper ontology in conjunction with an inference engine. After a review of available ontologies and inference engines it was decided to translate

Impact of Model-Driven Standards

January 1, 2003
Author(s)
David W. Flater
The Object Management Group (the consortium that issues the Common Object Request Broker Architecture and Unified Modeling Language standards) is making the transition from a standards architecture in which only interface definitions are normative to one
