Description<br />
Redistribution <strong>of</strong> the program, in source code or<br />
other form, must be allowed without a fee.<br />
The source code for program must be available at no<br />
charge, or a small fee to cover cost <strong>of</strong> distribution <strong>and</strong><br />
media. Intermediate forms such as the output <strong>of</strong> a<br />
preprocessor or translator are not allowed. Deliberately<br />
obfuscated source code is not allowed.<br />
Distribution <strong>of</strong> modified s<strong>of</strong>tware must be allowed<br />
without discrimination, <strong>and</strong> on the same terms as<br />
the original program.<br />
The license must allow modifications, derived works,<br />
be technology neutral. It must not restrict other s<strong>of</strong>tware,<br />
<strong>and</strong> must not depend on the program being<br />
part <strong>of</strong> a particular s<strong>of</strong>tware distribution.<br />
The license may require derived <strong>and</strong> modified works<br />
to carry a different name or version number from the<br />
original s<strong>of</strong>tware program.<br />
The license must not restrict the program to specific<br />
field <strong>of</strong> endeavour, <strong>and</strong> must not discriminate against<br />
any person or group <strong>of</strong> persons.<br />
Table 3.2: The criteria that defines an Open Source S<strong>of</strong>tware System.<br />
systems are distributed free <strong>of</strong> cost, the licensing models <strong>of</strong>ten restrict<br />
alteration <strong>and</strong> how they can be used <strong>and</strong> distributed.<br />
Projects that develop <strong>and</strong> distribute Open Source S<strong>of</strong>tware have over<br />
the past two decades championed a (radical) paradigm shift in legal<br />
aspects, social norms, knowledge dissemination <strong>and</strong> collaborative development<br />
[200]. One <strong>of</strong> the most compelling aspects <strong>of</strong> Open Source<br />
S<strong>of</strong>tware projects is that they are predominantly based on voluntary<br />
contributions from s<strong>of</strong>tware developers without organisational support<br />
in a traditional sense [202]. The typical open source model pushes for<br />
operation <strong>and</strong> decision making that allows concurrent input <strong>of</strong> divergent<br />
agendas, competing priorities, <strong>and</strong> differs from the more closed,<br />
centralised models <strong>of</strong> development [83, 215, 234]. These open source<br />
projects have over time evolved tools <strong>and</strong> techniques by experimenting<br />
with a range <strong>of</strong> ideas on how best to organise <strong>and</strong> motivate s<strong>of</strong>tware development<br />
efforts, even when developers are geographically dispersed<br />
<strong>and</strong> not provided any monetary compensation for their efforts. In these<br />
