perfsonar development work

Hi Jason, all

I'm not sure who I should send this question since LS IMHO only 
stores opaque data in the eXistDB.

Currently the message we want to use in the registration is:

<nmwg:message type="LSRegisterRequest"
              id="msg1"
              
xmlns:perfsonar="http://ggf.org/ns/nmwg/tools/org/perfsonar/1.0/";
              xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";
              
xmlns:psservice="http://ggf.org/ns/nmwg/tools/org/perfsonar/service/1.0/";
              xmlns:nmwgt="http://ggf.org/ns/nmwg/topology/2.0/";
              
xmlns:netutil="http://ggf.org/ns/nmwg/characteristic/utilization/2.0/";>

    <nmwg:metadata id="serviceLookupInfo">
        <perfsonar:subject id="commonParameters" 
xmlns:perfsonar="http://ggf.org/ns/nmwg/tools/org/perfsonar/1.0/";>
            <psservice:service id="serviceParameters" 
xmlns:psservice="http://ggf.org/ns/nmwg/tools/org/perfsonar/service/1.0/";>
                <psservice:serviceName>Topology 
Service</psservice:serviceName>
                
<psservice:accessPoint>http://tux.rediris.es:8090/axis/services/TopologyService</psservice:accessPoint>
                <psservice:serviceType>TOPS</psservice:serviceType>
                <psservice:serviceDescription>Topology Service, 
perfSONAR</psservice:serviceDescription>
            </psservice:service>
        </perfsonar:subject>
    </nmwg:metadata>

    <nmwg:data id="data0" metadataIdRef="serviceLookupInfo"/>

</nmwg:message>

I think this is ok, but it lacks something we need:

We are insterested in specifying the domain_name for which the Topology 
Service is
serving topology data.

I have seen Service.java but there is no way of specifying domain_name or 
analogous, 
I also took a look at other .java files but found nothing.

Currently we are exporting the domain_name as the institution attribute of a 
Node,
but I don't see a proper way for this case.

how I could add this information to the registration?

Also, can somebody confirm me that the data element can be empty?

Thanks so much

        Ulisses
