perfsonar development work

[Nicolas Simar <>]

Hi Anand,

thanks for this first set of information.

So basically, you are looking for an API that you could use to register 
pairs of parameters-values (both not hardcoded), so the API and the LS 
protocol only carries those pairs of value.

One idea you had from your past experience with EGEE would be to start 
from the test clients that have been developed. Waldemar (Cc-ed) has 
been working on such a similar issue and can provide some input on how 
AMPS delivered an API to EGEE.

Your timeline is Y3.

I suggest to set-up a conf call for next week between AMPS and LS to 
define the requirements and how it could work, so that we could 
investigate on our side the time it would take.
Szymon Torcha will organise that conf call.

To prepare that conf call, you would like to have some specification of 
the LS and of its interface. Szymon will send them.

Cheers,
Nicolas
