ENQUIRE
ENQUIRE was a software project written in 1980 by Tim Berners-Lee at CERN,[2] which was the predecessor to the World Wide Web.[6] The requirements for setting up a new system were compatibility with different networks, disk formats, data formats, and character encoding schemes, which made any attempt to transfer information between dissimilar systems a daunting and generally impractical task.The links had different meanings and about a dozen relationships which were displayed to the creator, things, documents and groups described by the card.[1][2] Further development stopped because Berners-Lee gave the ENQUIRE disc to Robert Cailliau, who had been working under Brian Carpenter before he left CERN.[2] ENQUIRE was written in the Pascal programming language and implemented on a Norsk Data NORD-10 under SINTRAN III,[2][4][6][8][9] and version 2 was later ported to MS-DOS and to VAX/VMS.
