All;

The LS is able to house data such as this:

 <nmwg:data xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/"; 
id="topo.d.26" metadataIdRef="topo.md.1">
   <nmtb:node 
xmlns:nmtb="http://ogf.org/schema/network/topology/base/20070828/"; 
id="internet2.d.26">
     <nmtb:address type="hostname">lowrider.east.isi.edu</nmtb:address>
     <nmtb:relation type="connectionLink">
       <nmtb:linkIdRef>
         
urn:ogf:network:domain=dcn.internet2.edu:node=wash-vlsr:port=10.100.80.221-102:link=1
       </nmtb:linkIdRef>
     </nmtb:relation>
   </nmtb:node>
 </nmwg:data>

This is a mapping of a URN (used in DCN to map a physical device or 
endpoint) to a hostname (or ip address).


Query to get one when you know one:

declare namespace nmwg="http://ggf.org/ns/nmwg/base/2.0/";;
declare namespace 
nmtb="http://ogf.org/schema/network/topology/base/20070828/";;          
//nmwg:data/nmtb:node/nmtb:address/text()[../../nmtb:relation[@type="connectionLink"]/nmtb:linkIdRef[text()="urn:ogf:network:domain=dcn.internet2.edu:node=wash-vlsr:port=10.100.80.221-102:link=1"]]

And the other way:

declare namespace nmwg="http://ggf.org/ns/nmwg/base/2.0/";;
declare namespace 
nmtb="http://ogf.org/schema/network/topology/base/20070828/";;   
//nmwg:data/nmtb:node/nmtb:relation/nmtb:linkIdRef/text()[../../../nmtb:address[text()="lowrider.east.isi.edu"]]

Bonus web interface to DCN info (this demo server is not live, feel free 
to play with it):
