perfsonar development work

[maxim <>]

 Hello to Everyone,
I am looking into building PingER MA SetupDataResponse as the  
interoperable piece pf perfSONAR infrastructure. For that I've tried to 
gather information about what
kind of metadata variations were implemented by services as part of  
SetupDataResponse messages. 
I've taken these schema pieces from functional testing directory.
For example JavaRRD has this:
-----------------------------
    (   Subject | FilterMetadataContent | MetadataKeyContent
     ) &
     EventType? &
     Parameters?
----------------------
where Parameters =      element nmwg:parameters { ParametersContent } &   
element select:parameters { ParametersContent }?
and the same Parameters might be in the FilterMetadataContent part. Is it 
expected behavior ?

On other hand the  sshtelnet has this variation:
---------------------------
    Subject,
    Parameters?,
    EventType? 
----------------------
And  E2Emon has very different piece of metadata and it seems like not 
supporting eventType at all:
----------------------
element nmwg:subject {
Identifier &
SubjectIdRef? &
(
MessageNode |
MessageLink
)
-------------------
So, my question is  - what pieces and in what order
"must be" supported by service for MDM release ?
 
   Thanks,
             Maxim Grigoriev.
