A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVib1JwpEbGdrcN5Y29ycA" class="cyc_term">Specification</a>. Each instance of this collection is not a computer program itself (i.e. lines of code), but an abstract characterization of how a program should behave. For instance, a sorting program can be specified by requiring that the program's output be a list of the same elements as the input such that no element follows an element that is greater than it. A notable example of a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjDLZwpEbGdrcN5Y29ycA" class="cyc_term">ProgramSpecification</a> is UNIX - which is not (contrary to popular belief) an operating system per se, but a specification to which many different operating systems (instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvwJcVZwpEbGdrcN5Y29ycA" class="cyc_term">UnixOS</a>) conform. Note that instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjDLZwpEbGdrcN5Y29ycA" class="cyc_term">ProgramSpecification</a> do not necessarily specify single, discrete programs -- thus many of the internet's &quot;RFC&quot; protocol-establishing documents (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwL2Ud5wpEbGdrcN5Y29ycA" class="cyc_term">RequestForComments_Internet</a>) fall into this collection.
