perfSONAR User Q&A and Other Discussion

[Vlada Macek <>]

Hi,

during the testing of the new LS client against
http://loco4.man.poznan.pl:8090/axis/services/LookupService, we've found
the responses deviate somehow from the specifications on
wiki.perfsonar.net. Can that mean the LS is old version? I think the
responses are vague. When the items below get corrected, the responses
will be better parsable:

   1. Returned the result codes in the form 'result.success' instead of
      'success.ls.register' for registration operation. Should I fix the
      client to accept this answer for success? I consider it unclean
      solution.

   2. 'id' attribute in response's data and metadata get strange "_0"
      suffix, for example 'resultCodeMetadata_0'. I think unified
      'resultCodeMetadata' and 'resultCodeData' ids would be great for
      parsing and I vote for them to be labeled required on the page
      http://wiki.perfsonar.net/jra1-wiki/index.php/LS_Messages.

   3. Response <nmwg:message> root element does not hold the required
      'metadataIdRef' attribute referencing the 'id' of the request.


My client parses the registration response using this xpath expression,
which I consider good:

/nmwg:message[@type="LSRegisterResponse"
 and
metadataIdRef="ls_client_request"]/nmwg:metadata[@id="resultCodeMetadata"]/nmwg:eventType

The items 2. and 3. above both keep the expression from finding the
correct <eventType> and item 1. means the string success.ls.register
cannot be successfully matched to indicate success.

If I may, I ask the responsible person for response. Thanks in advance.
