Not really.

The examples I sent this morning are as follows:

1)SetupDataRequest_FirstMeta.xml  - this has data linked to the FIRST metadata
and  is working, i.e. it retrieves some data for the interface.  

2)SetupDataRequest_LastMeta.xml  - has data linked to the LAST metadata and is
NOT working, i.e. the response does not contain data.

The problem is that PerfsonarUI was communicating with the previous releases
with requests similar to SetupDataRequest_LastMeta.xml  , the data linked to
the LAST metadata of the chain.  However, this request does not work with the
recent SQL MA. 

There is no problem to change the philosophy from the client side and generate
requests with data linked to the FIRST data for the new releases, but we have
to be sure this is the right way. It is slightly confusing that the Interface
specification says the data should be linked to the LAST metadata, which
doesn't work with current RCs.  
The Example No.2 from Interface specification of SQL MA also links data to the
LAST metadata.

Regards,
Nina
