Hi Maciej,

I don't remember if I have asked you this in the past, could you answer them? 
please note
that I'm going to be away until 21st of agust. Thanks so much.

Some questions about the protocol:

- about the register message

  the following fields [1] must be filled?

  <nmwg:data id="data0" metadataIdRef="serviceLookupInfo"> [1 // includes 
it's childs]
       <nmwg:metadata id="meta1">
           <perfsonar:subject id="subj1"       
                   
xmlns:perfsonar="http://ggf.org/ns/nmwg/tools/org/perfsonar/1.0/";>
               <nmwgt:interface 
xmlns:nmwgt="http://ggf.org/ns/nmwg/topology/2.0/";>
                   
<nmwgt:hostName>atlang-hstnng.abilene.ucaid.edu</nmwgt:hostName>
                   <nmwgt:ifName>unknown</nmwgt:ifName>
                   <nmwgt:ifDescription>
                         
hstn:oc192(p2p)::show:intracloud</nmwgt:ifDescription>
                   <nmwgt:ifAddress type="ipv4">198.32.8.34</nmwgt:ifAddress>
                   <nmwgt:direction>in</nmwgt:direction>
                   <nmwgt:capacity>10000000000</nmwgt:capacity>
               </nmwgt:interface>
           </perfsonar:subject>
           <nmwg:eventType>utilisation</nmwg:eventType>
       </nmwg:metadata>


  If yes, I don't understand the need for such fields

  Also, if the register message doesn't contain [1], maybe there is not a lot 
of 
  advantage having a separate keepalive message. Currently I periodically 
re-register.
  Is this wrong? Probaly I should use a sepparate the keepalive the message, 
isn't it?

- about the Keep alive message:

        
http://wiki.perfsonar.net/jra1-wiki/index.php/Example_LSKeepaliveRequest
        
  I understand that the only field that has to be customized to each service 
is the URL that
  points to the service:

        <nmwg:parameter name="lsKey">
                
http://reed.man.poznan.pl:8080/axis/services/MA</nmwg:parameter>
        </nmwg:parameters>

  and the URL should match be the same as in the accessPoint of the register 
message:

  <psservice:accessPoint>
                     http://reed.man.poznan.pl:8080/axis/services/MA
  </psservice:accessPoint>

  otherwise, the keepalive will not take place. The rest of the message 
should be as is in the example. 

- also maybe you should update the page 
http://wiki.perfsonar.net/jra1-wiki/index.php/Lookup_Service_Protocols
  when you say "Hierarchy of result and error codes, and their 
implementation, are still the subject of discussion."

  and instead put a reference to ls.success.registration and update the 
eventType in the example XML response?
