===Active URI Scheme===
<!-- Add a Wiki Page on active: URI -->
The ''active'' URI scheme was proposed by [[Hewlett-Packard]] as a means to encode a [[functional program]] within a URI.
<pre>
active: {function-name} [+ {parameter-name} @ {parameter-value-URI}]*
</pre>

For example, the following URI calls a random number generator
<pre>active:random</pre>

and the following uses an [[XSLT]] service to transform an [[XML]] document with an XSLT stylesheet:
<pre>active:xslt+operator@file:/style.xsl+operand@file:/document.xml</pre>

Because the argument values may be URI addresses themselves, a tree-structured set of function calls can be encoded in a single URI.
