perfsonar development work

["Nina Jeliazkova" <>]

Hi Nicolas,

I guess you mean JRA5 (not JRA4), right?

As far as perfsonarUI is concerned, we would be happy to implement the
required functionality for displaying eduroam metrics, provided that the
remaining building blocks of such service become available.

BTW, at some point it might be wise to discuss with JRA5's leader Juergen
Rauschenbach whether it would be feasible to claim the funding for
implementing such functionality in perfsonarUI from ISTF's contribution to
JRA5.

Kind regards,
Nina
