![]() ![]() Safari version 2.0 introduces the ability to save complete websites using the proprietary WebArchive format (details at Safari version history). The initial version of Git, a version control system with support for data integrity, is released. The International Internet Preservation Consortium is founded. TinyURL, the first notable URL shortening service, is launched. Version 1.0 of the Parity Volume Set specification, used in Par1, is published. The National Digital Information Infrastructure and Preservation Program (NDIIPP) launches. The first version of HTTrack, a free and open source Web crawler and offline browser, is released. cURL can be used to download files over a network. It is known at this point as HttpGet, would briefly rename itself to urlget, and would finally rename itself to cURL in March 1998. ĬURL, a computer software project providing a library and command-line tool for transferring data using various protocols, releases its initial version of the tool. It became a fundamental document in the field of digital preservation that helped set out key concepts, requirements, and challenges. Preserving Digital Information: Report of the Task Force on Archiving of Digital Information (Donald Waters, John Garrett, eds.) is published. Since this year, Alexa Internet has donated its crawl data to the Internet Archive. Īlexa Internet is founded by Brewster Kahle. The Internet Archive is founded by Brewster Kahle. The initial version of the command-line downloading program Wget, then known as Geturl, is released. Possibly the earliest reference to the term "digital preservation" (to mean converting analog media to digital and preserving in digital form) is from this year. Ĭontinuous data protection, the technique of backing up computer data by automatically saving a copy of every change made to that data, is patented by British entrepreneur Pete Malcolm. Although failures would rise in proportion to the number of drives, by configuring for redundancy, the reliability of an array could far exceed that of any large single drive. In their June 1988 paper "A Case for Redundant Arrays of Inexpensive Disks (RAID)", presented at the SIGMOD conference, they would argue that the top performing mainframe disk drives of the time could be beaten on performance by an array of the inexpensive drives that had been developed for the growing personal computer market. Gibson, and Randy Katz at the University of California, Berkeley in 1987. The term " RAID" is invented by David Patterson, Garth A. The compact disc (CD) as well as the CD player first become commercially available in Japan. ![]() ![]() Marc Rochkind develops the Source Code Control System at Bell Labs.
