Think about how it works with other legal citations. &quot;Fed. R. Civ. P. 12(b)(6).&quot; means something to a lawyer and is irrespective of where they would physically find that court rule to read.<p>An issue with Perma&#x27;s id format is it doesn&#x27;t contain anything to differentiate it from any other use of two sets of four uppercase letters or numbers separated by a dash, it&#x27;s not &quot;LAWCITE:A1C4-5F7H&quot; it&#x27;s just &quot;A1C4-5F7H.&quot; The domain name could serve that purpose so wherever else Perma&#x27;s content is stored, the route should contain perma.cc. So all of the following would have the same content, e.g.:
<a href="http:&#x2F;&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;perma.cc&#x2F;48VC-ZS62</a>
<a href="http:&#x2F;&#x2F;archive.org&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;archive.org&#x2F;perma.cc&#x2F;48VC-ZS62</a>
<a href="http:&#x2F;&#x2F;doomsday.preppers&#x2F;rebuilding-America&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;doomsday.preppers&#x2F;rebuilding-America&#x2F;perma.cc&#x2F;48VC-ZS...</a><p>And in reference to the other comment, if the .cc TLD goes away for some reason, &quot;perma.cc&quot; could still remain a part of the URL even at the project&#x27;s &quot;home&quot; site, e.g.:
<a href="http:&#x2F;&#x2F;perma.law.harvard.edu&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;perma.law.harvard.edu&#x2F;perma.cc&#x2F;48VC-ZS62</a>
<a href="http:&#x2F;&#x2F;perma-cc.com&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;perma-cc.com&#x2F;perma.cc&#x2F;48VC-ZS62</a>
<a href="http:&#x2F;&#x2F;perma.mars&#x2F;perma.cc&#x2F;48VC-ZS62" rel="nofollow">http:&#x2F;&#x2F;perma.mars&#x2F;perma.cc&#x2F;48VC-ZS62</a>
