CERN celebrates Web anniversary […]. Berners-Lee's unique insight in marrying hypertext to the Internet CERN celebrates Web anniversary […]. Berners-Lee's unique insight in marrying hypertext to the Internet to give the Web its simple point-and-click ease of use certainly helped. And the fact that CERN had the foresight to ensure that the Web became part of the public domain, and not the property of any company or individual, was decisive François Fluckiger, DMM, 4 June 2003 9

Distribution of CERN WWW software Francois Fluckiger (fluckiger@vscrna. cern. ch) Tue, 15 Nov 1994 Distribution of CERN WWW software Francois Fluckiger ([email protected] cern. ch) Tue, 15 Nov 1994 23: 05: 59 +0100 Messages sorted by: [ date ][ thread ][ subject ][ author ] Next message: David Koblas: "How about an "IF" markup construct. . . " Previous message: [email protected] spawar. navy. mil: "Windows Help to HTML conversion" Dear Colleagues, Some of you asked about the conditions for the distribution of new versions of the CERN WWW Library of Common Code (libwww), the CERN Line Mode Browser (www) and the WWW HTTP Daemon (httpd). The new versions will remain freely available, for general use, and at no cost. The only change is that the material distributed will remain copyrighted by CERN. As a consequence, a copyright notice will have to appear in copies, but also, the rights of the users will be protected, in particular by preventing third parties to turn free software into proprietary software, and deny the users the rights to freely use the material. These principles are those used by most distributors of free software, including the X consortium. The proper copyright notice is being ratified and will be available in a few days. We hope all those who have trusted CERN WWW software will continue to do so, and will appreciate that these conditions not only maintain the free distribution but better protect it.

CERN celebrates Web anniversary […] In the words of the inventor himself, CERN celebrates Web anniversary […] In the words of the inventor himself, "CERN's decision to make the Web foundations and protocols available on a royalty free basis, and without additional impediments, was crucial to the Web's existence. Without this commitment, the enormous individual and corporate investment in Web technology simply would never have happened, and we wouldn't have the Web today.

Castor CASTOR DISTRIBUTION CONDITIONS CASTOR Distribution: 24 July 2002 CERN allows free distribution of Castor CASTOR DISTRIBUTION CONDITIONS CASTOR Distribution: 24 July 2002 CERN allows free distribution of CERN owned software under the same conditions as the gnu public licence. The definitive version of this is to be found at http: //www. gnu. org/copyleft/gpl. html Some of the software included in the tarball (currently db and imake) is itself being redistributed under similar 'right to use and distribute' conditions. The CASTOR system is distributed as a tarball containing all the server components plus the interfaces to the devices (eg tape drives and robotics) currently in use at CERN will integrate interface code to other devices sent in by outside institutions as far as possible but cannot guarrantee correct working. Use of some devices may require the user to purchase additional software licences from a third party. CERN cannot provide such software. The source contains an overview README file, a version history and comments and installation instructions but correct installation and setting up at any site is the responsibility of the site. CERN is preparing a detailed installation guide as an aid and will answer technical questions sent to castor. [email protected] ch as far as possible. It is assumed that installation will be done by local staff with the correct level of computer system administration expertise and CERN cannot provide such expertise should this not be the case. The tarball can be obtained from the CERN web site http: //cern. ch/castor Users should use the 'Download' link then the link 'CERN or AUTHORISED people'. This will ask for a userid and password. Requestors should obtain these keys in advance from castor. [email protected] ch and they should not be revealed to a third party. castor.
