Hi all

I wanted to know for how long a register or a keepalive message makes the 
data valid

looking at

        http://wiki.perfsonar.net/jra1-wiki/index.php/Lookup_Service_resources

I haven't found this information. 

I was interesting becuase in the topology service I was planning a similar 
register procedure.

Maybe the register/keepalive __response__ should include the number of 
seconds for which the data
is garateed it will be stored?

Thanks
