Every thing in the Cyc ontology -- every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> (of any kind), every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>, and every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> -- is an instance of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Similarly, every collection is a subcollection of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBDpwpEbGdrcN5Y29ycA" class="cyc_term">genls</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>. Trivially, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a> is both an instance of and a subcollection of itself, and is not a subcollection of any other collection. (Note that the above reference to "every thing in the Cyc ontology" is not meant to be limited to things actually reified in the Cyc system, but includes (e.g.) every instance -- reified or not, known or not -- of every collection recognized by Cyc.) URL UniformResourceLocator A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwGD5pJwpEbGdrcN5Y29ycA" class="cyc_term">ContactInfoString</a>. Instances of this collection are commonly called "web addresses". Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvmQlOpwpEbGdrcN5Y29ycA" class="cyc_term">UniformResourceLocator</a> (often abbreviated "URL") is a string that can be used to specify an object on the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVnZe5wpEbGdrcN5Y29ycA" class="cyc_term">Internet</a>, such as a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvXJevZwpEbGdrcN5Y29ycA" class="cyc_term">WebPage_CW</a> or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwRZ4-pwpEbGdrcN5Y29ycA" class="cyc_term">InternetNewsgroup</a>. The first part of a URL is the name of a particular <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvvn3fJwpEbGdrcN5Y29ycA" class="cyc_term">InternetProtocol</a>, such as http, ftp, news, telnet, or mailto, and is followed by a colon. The part immediately following the first colon is different for each protocol, but generally is a string of characters identifying a file location, a username, and/or a password. Some URLs have a third part, consisting of '?' or '#' followed by a query string or the name of a location within a web page. Examples include <a href= "ftp://ftp.downlodes.com/pub/stuff/file.zip">ftp://ftp.downlodes.com/pub/stuff/file.zip</a>, <a href= "http://www.myorg.org/index.html">http://www.myorg.org/index.html</a>, <a href= "news:alt.hypertext">news:alt.hypertext</a>, <a href= "mailto:santa@northpole.com">mailto:santa@northpole.com</a>. wikipediaArticleURL (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rbA_4EHR9Ed2AAADggVfs8g" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in #$Wikipedia-WebSite THING is described by an article located at URL wikipediaArticleURL
