RED HAT AND OPEN SOURCE

Who Is Red Hat?

Red Hat is more than a software company. We are the bridge between the communities that create open source software and the enterprise customers who use it. Red Hat makes the rapid innovation of open source technology consumable in mission-critical, enterprise environments.

Red Hat combines a superior development model with a customer-friendly business model that gives customers the choice, flexibility, and power to build an IT infrastructure that solves their business problems and makes their IT a strategic advantage.

We do this by sharing. We share our expertise, our code, and our knowledge. We sell subscriptions for enterprise technology and services, we stand up for open source ideals, and we foster greater participation in the open source process. Red Hat is a catalyst for a technology movement that has already changed the world.

What is Open Source?

Software is “open source”, or “free”, if the following two conditions are present: (1) the software is distributed in source code form, or
else the source code is made readily available to the user at no additional charge, and (2) the software is distributed under terms granting royalty-free copyright permissions to the user to copy, modify and redistribute without undue restriction, as determined by open source
software developer community standards.

In determining such standards, there have been three particularly influential sources of authority: 1) the Free Software Foundation, with its four-element Free Software Definition; 2) the Debian Project, with its ten-element Debian Free Software Guidelines (DFSG); and 3) the Open Source Initiative, with its ten-element Open Source Definition (derived from the DFSG).

In general, open source licenses do not restrict private copying or modification, and only restrict distribution or public use in certain
accepted ways considered compatible with software freedom, ranging from mere notice preservation requirements to ‘copyleft’ requirements that require modified versions to be placed under the same license as the original work, accompanied by source code for the modified version.
