perfsonar development work

[Nicolas Simar <>]

Hi,

Roman reminded us that there were some changes that are not backward 
compatible that need introducing in the schema.

Could you please look at them (two, see below) and tell us the impacts 
they have on your development? (Is it a big/medium/small change) for 
this Friday.

We are evaluating to introduce them in 3.0. (the visualisation need to 
cope with both type of messages, the functional test only with the new 
one - correct?).

Cheers,
Nicolas

1) use of eventType element instead of parameter 'supportedEventType'

example:

   <nmwg:metadata id="meta1">
       <netutil:subject id="subj1">
           <nmwgt:interface>
               <nmwgt:hostName>test-hostName</nmwgt:hostName>
               <nmwgt:ifAddress type="ipv4">10.1.2.3</nmwgt:ifAddress>
               <nmwgt:ifName>test-0</nmwgt:ifName>
               <nmwgt:ifDescription>test descripyion</nmwgt:ifDescription>
               <nmwgt:direction>in</nmwgt:direction>
               <nmwgt:authRealm>TestRealm</nmwgt:authRealm>
               <nmwgt:capacity>1000BaseT</nmwgt:capacity>
           </nmwgt:interface>
       </netutil:subject>
       <nmwg:parameters>
           <nmwg:parameter
name="supportedEventType">http://ggf.org/ns/nmwg/characteristic/utilization/2.0</nmwg:parameter>
       </nmwg:parameters>
       <!--
<nmwg:eventType>http://ggf.org/ns/nmwg/characteristic/utilization/2.0</nmwg:eventType> 

-->
   </nmwg:metadata>

 (commented line is that new thing which replaces parameter)


2) use of netutil namespace (related with eventType value) instead of
nmwg for datum element in response

example with nmwg namespace:

   <nmwg:data id="d2" metadataIdRef="m2">
       <nmwg:datum timeType="unix" timeValue="1186735500"
value="7999.161468670205" valueUnits="Bps"/>
       ....
   </nmwg:data>


example with netutil namespace:

   <nmwg:data id="d2" metadataIdRef="m2">
       <netutil:datum timeType="unix" timeValue="1186735500"
value="7999.161468670205" valueUnits="Bps"/>
       ....
   </nmwg:data>




> and the impact on the visualisations (changed needed)?

It's the question to people who work on this.


I'd like to stress that the mentioned changes is not my personal
initiative (don't worry; it's not again new thing from my side :) Some
time ago (before v. 2.3) I had the discussion with Jason and Jeff and
those 2 things were discussed (I think they use them in their
implementation but I didn't check it)
