Earlier Projects & Other Areas of Interest


Application Gateway System

The Application Gateway System (AGS), a distributed server system consisting of multiple heterogeneous servers that appears as a single high performance system on the Internet.


Computer Science Technical Reports Project

The Computer Science Technical Reports (CS-TR) project, funded by the Defense Advanced Research Projects Agency, developed network access to archives of technical information in the domain of computer science, with the goal of evolving knowledge in the field of information storage, search, and retrieval. The Digital Object Architecture project continues the architecture work of the CS-TR project.


Congressional Testimony (1998)

Congressional testimony on the Domain Name System and Electronic Commerce.


Cross Industry Working Team

CNRI supported and participated in the Cross Industry Working Team (XIWT), a multi-industry coalition that was committed to defining the architecture and key technical requirements for a powerful, sustainable national information infrastructure (NII). (See Managing Access to Digital Information, May 1997, and other XIWT White Papers.


Defense Virtual Information Architecture (DVIA)

The Defense Technical Information Center (DTIC), the Defense Advanced Projects Agency (DARPA), and CNRI extended and transfered CNRI's Digital Object Architecture work into a pilot digital library implementation, the Defense Virtual Information Architecture, adapted to DTIC's needs and using DTIC data.


Distributed Integration Testbed

The Distributed Integration Testbed Project was a three year effort that included the D-Lib Test Suite, metrics and quantitative measures for digital libraries research, interoperability research, and experiments in electronic publishing including D-Lib Magazine.


Electronic Payments Forum

The EPF was initiated in November, 1995, to provide a mechanism for information exchange and to identify and examine issues regarding financial payment systems on the Internet. The EPF was organized under the auspices of CommerceNet, the Financial Services Technology Consortium (FSTC) and the Cross-Industry Working Team (XIWT), dedicated to the advancement of the Global Information Infrastructure (GII).


Gigabit Testbed Initiative

The Gigabit Testbed Initiative was a major effort by approximately forty organizations representing universities, telecommunication carriers, industry and national laboratories, and computer companies to create a set of very high-speed network testbeds and to explore their application to areas such as weather modeling, chemical dynamics, radiation oncology, and geophysics data exploration. This effort was funded by the National Science Foundation (NSF), the Defense Advanced Research Projects Agency (DARPA), and by industry. See the Testbed Initiative Final Report (PDF Version: hdl:42634537/5036; HTML Version: hdl:4263537/5035).


Grail® Internet Browser

Grail, an Internet browser written in Python, is a web browser primarily for Unix that is easily extensible to support new protocols or file formats.


Initial CNRI Repository Software

Initial CNRI Repository Software is based on the digital object architecture and provides distributed digital object services via an open architecture in the network environment.



IOPS.ORG promoted cooperation and information-sharing across and among Internet service providers in the public interest, including joint problem resolution, technology assessment, and global Internet scaling and integrity. It supported engineering analysis, system simulation and testing, and interaction with other groups and organizations.



MAGIC-II, a collaborative project involving seven major participants, developed a large-scale distributed information system based on a very general paradigm in which high-performance computing, storage, and communications were used to provide rapid access to real-time data sources and to large volumes of stored data, the existence and locations of which may not be known in advance. Applications that used this paradigm arose in a variety of situations including military operations, intelligence imagery analysis, and natural disasters.


National Digital Library Program at the Library of Congress

CNRI worked with the Library of Congress to provide technology for the National Digital Library Program.


Python® and JPython®

Python is a state-of-the-art portable, interpreted, object-oriented programming language that runs on most platforms.

JPython is an implementation of Python that is seamlessly integrated with the Java platform, providing a powerful companion to Java where use of a higher level language is appropriate.



Stackworks is an activity which focuses on the organization and management of archival collections of information.


Spoken Dialogue Systems

Spoken dialogue systems enable users to interact with computer systems via natural and intelligent dialogues, as they would with human agents. Development of such systems requires a wide range of speech and language technologies. These include automatic speech recognition to convert audio signals of human speech into text strings, language understanding to interpret the meaning of the recognized utterances, and dialogue processing and response planning to generate cooperative and useful system replies. Text-to-speech synthesis is used to convert the system utterance into actual speech output.

CNRI participated in research in creating speech interfaces that can interact in natural and fluid conversations with people. The projects were concerned with building systems that made it easier for people to navigate information using natural speech. The goal was to develop methodologies that would enable machines to understand the context and nuances that people employ in conversation to conduct day-to-day tasks.


Transient Network Architecture (TNA)

Researchers from CNRI and the Electrical and Computer Engineering Department of the University of New Mexico collaborated on Transient Network Architecture, based on the notion of a pervasive transient mobile network in which all communications occur between persistently identified entities. Such a network, which is mobile and ubiquitous in nature, allows entities to form and associate themselves with coordinated ad-hoc networks. These networks are provided the means to integrate almost seamlessly with each other. All entities that are part of this network are identified with handles and traffic routing and communication are also performed based on these identifiers. This translates into effectively replacing IP addresses with handles at the network level and opens the door to truly abstract persistent communications.


US Copyright Office CORDS

CNRI helped to develop CORDS (Copyright Office Registration, Recordation, & Deposit System), a limited production system of the US Copyright Office that provided electronic registration and deposit of digital objects for copyright.
