Hi,


Today I've made important change in the svn trunk: EventType in metadata 
configuration file has been replaced by parameter element (name 
supportedEventType).

Example:

before the change:

   <nmwg:metadata id="meta1-test">
       <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 description</nmwgt:ifDescription>
               <nmwgt:direction>in</nmwgt:direction>
               <nmwgt:authRealm>TestRealm</nmwgt:authRealm>
               <nmwgt:capacity>1000BaseT</nmwgt:capacity>
           </nmwgt:interface>
       </netutil:subject>
       <nmwg:eventType">utilization</nmwg:eventType>
   </nmwg:metadata>


after the change:

   <nmwg:metadata id="meta1-test">
       <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 description</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">utilization</nmwg:parameter>
       </nmwg:parameters>
   </nmwg:metadata>




it has been done because metadata may support more than one eventType. 
So, for example above metadata describing an interface may be used not 
only for utilization but also for packet loss or other metric.

Example metadata configuration files are located in $PERFSONAR/conf 
directory.

Requests stay the same and use eventType element in metadata because 
they are used to fetch data related with certain eventType.
