 <p class="highlight"><b>A URI structure will not contain anything that could change</b><br />
 It is good practice that URIs do not contain anything that could easily change or that is expected to change like session tokens or other state information. URIs should be stable and reliable in order to maximize the possibilities of reuse that Linked Data brings to users. There must be a balance between making URIs 
 readable and keeping them more stable by removing descriptive information that will likely 
-change. For more information on this see <a href="http://www.w3.org/TR/webarch/#uri-opacity">Architecture of the World Wide Web: URI Opacity</a>.

 A SPARQL endpoint is a a service that accepts SPARQL queries and returns answers to them as SPARQL result sets. It is a best practice for datasets providers to give the URL of their SPARQL endpoint to allow access to their data programmatically or through a Web interface. A <a href="http://sparqles.okfn.org/">list of SPARQL endpoints</a> monitoring the availability, performance, interoperability and discoverability of SPARQL Endpoints is published by the Open Knowledge Foundation.
