<description>As an &quot;info&quot; URI an ARK has the form, NAAN + &quot;/&quot; + Name, where NAAN is a globally unique Name Assigning Authority Number given to an organization that assigns ARKs and Name is a string assigned by that organization.  A NAAN is a 5- or 9-digit number and a Name is a string of ASCII letters, digits, and the characters { = # * + @ _ $ }, not including the braces.  In addition, a Name may contain the characters { . / % - }, which are reserved to indicate variant form, logical containment, escaped octet, and a lexically ignorable separator, respectively.</description>

<description>ARKs are designed to be embeddable in URLs where the protocol and hostname provide branded (the current provider) actionability but are formally identity-inert in the sense that they do not participate in comparing two ARKs for equality.  To render an ARK as an &quot;info&quot; URI, first remove the protocol and hostname, if any; then remove any hyphens and any initial or final occurrences of { . / }.  The resulting string is case sensitive.</description>
