What is FOSS?

FOSS is Free Open Source Software, which is free to share and free to change. Proprietary software, on the other hand, restricts these freedoms — you can’t copy, share and modify it.

What’s in a name?

Free Software was defined in 1983, and is championed by the Free Software Foundation. It has an emphasis on the social aspects of software (Free software is a matter of liberty not price). The Open Source Initiative was established in 1998, promoting a less ideological and more business-friendly approach to the free software movement.

In practical terms, they’re very similar, so many people refer to them collectively as Free Open Source Software (FOSS).

Open Standards

Open Standards refer to specifications for hardware and software that are publicly available. For example, web pages are built using HTML. No one company controls HTML, instead a standards body called the W3C oversees new developments. This is in stark contrast to Adobe’s Flash SWF format.

FOSS programs generally use Open Standards for documents, eg OpenOffice.org uses XML, Inkscape uses SVG. Whereas proprietary software tends to use proprietary standards, eg Microsoft Office uses DOC, and Adobe Flash uses SWF.
