Hi,

we're trying to get some information from the topology service.

what we are trying to do is to plot some information from the  
topology service onto something like googlemaps. we have an example  
at http://134.79.24.133:8080/cgi-bin/gmaps.pl

the current version uses dns LOC records to determine the long lat  
location. if that fails it defaults to the use of geoiptools. of  
course, the link information shown is false (blindly uses the array  
of routers if the geographical location can be found), rather than  
information from bgp, cdp etc.

for optimal efficiency, we would like to be able to query for both  
the link information and the detailed node information on the same  
xml. for example:

=== example ===
<nmwg:message type="TopologyRequest"
        id="#tops"
        xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";
        xmlns:nmwgtopo3="http://ggf.org/ns/nmwg/topology/base/3.0/";>

  <nmwg:metadata id="#meta1">
    <nmwgtopo3:subject id="#sub1"></nmwgtopo3:subject>
    <nmwg:eventType>http://ggf.org/ns/nmwg/topology/actions/node/ 
list/detail</nmwg:eventType>
    <nmwgtopo3:parameters id="#params1"></nmwgtopo3:parameters>
  </nmwg:metadata>

  <nmwg:data id="#data1" metadataIdRef="#meta1"/>

  <nmwg:metadata id="#meta2">
    <nmwgtopo3:subject id="#sub2"></nmwgtopo3:subject>
    <nmwg:eventType>http://ggf.org/ns/nmwg/topology/actions/link/ 
list</nmwg:eventType>
    <nmwgtopo3:parameters id="#params2"></nmwgtopo3:parameters>
  </nmwg:metadata>

  <nmwg:data id="#data2" metadataIdRef="#meta2"/>

</nmwg:message>
======

however, the returned xml response only contains information  
regarding the link information and NOT the node information.  
(regardless of the order in which the <nmwg:data/> elements are placed.

is it possible to do a single request for such information? (ie both  
node and link info)

also, does any one else have any topology services from which we can  
query?

thanks,

Yee.
