The Corporation for National Research Initiatives (CNRI), based in Reston, Virginia, is a non-profit organization founded in 1986 by Robert E. Kahn as an "activities center around strategic development of network-based information technologies", including the National Information Infrastructure (NII) in the United States. [1]
CNRI develops the Handle System for managing and locating digital information. [2] CNRI obtained DARPA funding for the development of JPython (Jython), a Python implementation in and for Java, initially created by Jim Hugunin. [3] The MEMS and Nanotechnology Exchange (MNX) is an effort located at CNRI that provides semiconductor implementation services to the United States and was established with support from DARPA.
CNRI formerly operated the Secretariat of the Internet Engineering Task Force. [4] Guido van Rossum, pioneer for open source software and creator of Python, at one time worked for this company. The formation and early funding of the Internet Society were led by CNRI. At the first meeting of the Internet Society board, Vint Cerf, representing CNRI, offered, "In the event a deficit occurs, CNRI has agreed to contribute up to USD102000 to offset it." [5] In the event, the contribution was not needed. CNRI did cover many of the expenses of the Internet Society in 1992. They also paid Cerf's salary during 1993, when much of his time was devoted to building the Internet Society. [6]
In 1996, the Association of American Publishers announced that R. R. Bowker and the CNRI had been selected to design a Digital Object Identifier system. The effort was initiated after a year-long study of the need for a system to identify electronic copyright ownership and to manage the digital purchase of rights. [7] The CNRI Handle system was first demonstrated at a February 1997 meeting of the Professional/Scholarly Publishing (PSP) division of the AAP meeting in Washington, DC. [8] The Handle System is a technology specification for assigning, managing, and resolving persistent identifiers for digital objects and other resources on the Internet. The DONA System is under consideration at the ITU [9] and has been adopted by several countries. [10]
D-Lib Magazine was an on-line magazine dedicated to digital library research and development, produced by CNRI.
MNX was established with support from the United States Department of Defense (DoD), specifically, the Defense Advanced Research Projects Agency (DARPA). The MNX is a design and fabrication service provider to the United States research and development (R&D) community for micro- and nano-systems made using semiconductor-based fabrication methodologies. Since its founding in 1998, the MNX has completed over 3,000 different fabrication projects, many of these projects representing cutting-edge research having significant national security and economic importance. MNX has provided implementation services to over 1,000 organizations in the United States, including: defense contractors; DoD and Federal laboratories; leading academic researchers; fortune 500 companies; and many start-ups. The MNX at CNRI was founded and is managed by Dr. Michael Huff.
The MEMS Clearinghouse was originally established at USC/ISI with support from the United States Department of Defense (DoD), specifically, the Defense Advanced Research Projects Agency (DARPA). The MNX of CNRI took over the management of the MEMS Clearinghouse under the management of Dr. Michael Huff. It was then renamed the MEMSNet. The MEMSNet includes a number of information and service offerings including: an extensive material property database with references; MEMSTalk which is an on-line discussion groups of people interested in semiconductor technologies; news articles about semiconductor technologies; events and meetings; and more. At one time, MEMSNet was the most popular web site for MEMS technology.
CNRI developed the Digital Object (DO) Repository software, with digital object architecture which provides a mechanism for the creation of, and access to, digital objects as discrete data structures with unique, resolvable identifiers. [11]

The Internet Engineering Task Force (IETF) is a standards organization for the Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors.
MEMS is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometres in size, and MEMS devices generally range in size from 20 micrometres to a millimetre, although components arranged in arrays can be more than 1000 mm2. They usually consist of a central unit that processes data and several components that interact with the surroundings.
Zope is a family of free and open-source web application servers written in Python, and their associated online community. Zope stands for "Z Object Publishing Environment", and was the first system using the now common object publishing methodology for the Web. Zope has been called a Python killer app, an application that helped put Python in the spotlight.
Guido van Rossum is a Dutch programmer best known as the creator of the Python programming language, for which he was the "benevolent dictator for life" (BDFL) until he stepped down from the position on 12 July 2018. He remained a member of the Python Steering Council through 2019, and withdrew from nominations for the 2020 election.
Robert Elliot Kahn is an American electrical engineer who, along with Vint Cerf, first proposed the Transmission Control Protocol (TCP) and the Internet Protocol (IP), the fundamental communication protocols at the heart of the Internet.
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system. They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications.
A lab-on-a-chip (LOC) is a device that integrates one or several laboratory functions on a single integrated circuit of only millimeters to a few square centimeters to achieve automation and high-throughput screening. LOCs can handle extremely small fluid volumes down to less than pico-liters. Lab-on-a-chip devices are a subset of microelectromechanical systems (MEMS) devices and sometimes called "micro total analysis systems" (μTAS). LOCs may use microfluidics, the physics, manipulation and study of minute amounts of fluids. However, strictly regarded "lab-on-a-chip" indicates generally the scaling of single or multiple lab processes down to chip-format, whereas "μTAS" is dedicated to the integration of the total sequence of lab processes to perform chemical analysis.

They provide equipment, materials and services for the manufacture of semiconductors, photovoltaic panels, LED and flat panel displays, micro-electromechanical systems (MEMS), printed and flexible electronics, and related micro and nano-technologies.
Microfabrication is the process of fabricating miniature structures of micrometre scales and smaller. Historically, the earliest microfabrication processes were used for integrated circuit fabrication, also known as "semiconductor manufacturing" or "semiconductor device fabrication". In the last two decades microelectromechanical systems (MEMS), microsystems, micromachines and their subfields, microfluidics/lab-on-a-chip, optical MEMS, RF MEMS, PowerMEMS, BioMEMS and their extension into nanoscale have re-used, adapted or extended microfabrication methods. Flat-panel displays and solar cells are also using similar techniques.
Multi-project chip (MPC), and multi-project wafer (MPW) semiconductor manufacturing arrangements allow customers to share tooling and microelectronics wafer fabrication cost between several designs or projects.
A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source. The first CSAC physics package was demonstrated at the National Institute of Standards and Technology (NIST) in 2003, based on an invention made in 2001. The work was funded by the US Department of Defense's Defense Advanced Research Projects Agency (DARPA) with the goal of developing a microchip-sized atomic clock for use in portable equipment. In military equipment it is expected to provide improved location and battlespace situational awareness for dismounted soldiers when the global positioning system is not available, but many civilian applications are also envisioned. Commercial manufacturing of these atomic clocks began in 2011. The CSAC, the world's smallest atomic clock, is 4 x 3.5 x 1 cm in size, weighs 35 grams, consumes only 115 mW of power, and can keep time to within 100 microseconds per day after several years of operation. A more stable design based on the vibration of rubidium atoms was demonstrated by NIST in 2019. The new design has yet to be commercialized.
The programming language Python was conceived in the late 1980s, and its implementation was started in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to ABC capable of exception handling and interfacing with the Amoeba operating system. Van Rossum is Python's principal author, and his continuing central role in deciding the direction of Python is reflected in the title given to him by the Python community, Benevolent Dictator for Life (BDFL).. Python was named after the BBC TV show Monty Python's Flying Circus.
The Handle System is the Corporation for National Research Initiatives's proprietary registry assigning persistent identifiers, or handles, to information resources, and for resolving "those handles into the information necessary to locate, access, and otherwise make use of the resources".

In the early twenty-first century; foreign investment, government regulations and incentives promoted growth in the Indian electronics industry. The semiconductor industry, which is its most important and resource-intensive sector, profited from the rapid growth in domestic demand. Many industries, including telecommunications, information technology, automotive, engineering, medical electronics, electricity and solar photovoltaic, defense and aerospace, consumer electronics, and appliances, required semiconductors. However, as of 2015, progress was threatened by the talent gap in the Indian sector, since 65 to 70 percent of the market was dependent on imports.
