| ?:hexadecimal | "<span xmlns="http://www.w3.org/1999/xhtml"><p>
An encoding of a positive integer (from 0 to infinity) as a hexadecimal string that makes it easy to read and/or fun to present on the web.</p>
<p>The purpose of this way of representing hexadecimals is to enable users to copy and paste hexadecimal notations as shown by most browsers, keychains or tools such as opensso, into their rdf representation of choice. There are a wide variety of ways in which such strings can be presented. One finds the following:</p>
<pre>
e1 dc d5 e1 00 8f 21 5e d5 cc 7c 7e c4 9c ad 86
64 aa dc 29 f2 8d d9 56 7f 31 b6 bd 1b fd b8 ee
51 0d 3c 84 59 a2 45 d2 13 59 2a 14 82 1a 0f 6e
d3 d1 4a 2d a9 4c 7e db 90 07 fc f1 8d a3 8e 38
25 21 0a 32 c1 95 31 3c ba 56 cc 17 45 87 e1 eb
fd 9f 0f 82 16 67 9f 67 fa 91 e4 0d 55 4e 52 c0
66 64 2f fe 98 8f ae f8 96 21 5e ea 38 9e 5c 4f
27 e2 48 ca ca f2 90 23 ad 99 4b cc 38 32 6d bf
</pre>
<p>
Or the same as the above, with ':' instead of spaces. We can't guarantee that these are the only ways such tools will present hexadecimals, so we are very lax.</p>
<p>The letters can be uppercase or lowercase, or mixed. </p>
<p>Some strings may start with initial 00's, and can be stripped in this notation as they often are. Doing this could, in complement of 2 notation turn a positive number into a negative one, if the first hexadecimal character happens to be one of the set {'8', '9', 'a', 'A', 'b', 'B', 'c', 'C', 'd', 'D', 'e', 'E', 'f', 'F'} . As we interpret this string as a hexadecimal number leading 00s are not important (Complement of 2 notation and hexadecimal overlap for positive numbers)</p>
<p> In order to make this fun, we allow any unicode characters in the string. A parser should </p>
<ol>
<li>remove all non hexadecimal characters</li>
<li>treat the resulting as a hexadecimal representation of a number</li>
</ol>
<p>
This will allow people to make an ascii - better yet a UTF-8 - picture of their public key when publishing it on the web.
</p>
<p>
Cert hex is also a datatype property because we used to write it out like this
</p>
<pre>
[] a rsa:RSAPublicKey;
rsa:public_exponent [ cert:hex "e1 dc d5 ..."]
</pre>
<p> The above notation is now deprecated. Now we prefer the literal format below.</p>
<pre>
[] a rsa:RSAPublicKey;
rsa:public_exponent "e1 dc d5 ..."^^cert:hex .
