Dear nsi-wg, As an employee of ASTRON, working for the NEXPReS project and the possibilities to implement the techniques developed for this project for the long-term archive of LOFAR, I am following the discussions on nsi-wg mailing list. Recently I have seen some discussion on the possible implementation of availability querying in the 2.0 version of the protocol. Since this is an option which is very interesting for our use case, I was wondering what the status was. As far as I understood, showing the availability would be a choice of the NSA and it is yet undecided whether or not this option will be used. I thank you for your time, Yours sincerely, Yan Grange -- Yan Grange Wetenschappelijk programmeur/Scientific programmer NEXPReS ASTRON het Nederlands instituut voor radioastronomie the Netherlands Institute for Radio Astronomy Radiosterrenwacht/Radio observatory Oude Hogeveensedijk 4 Paviljoen west kamer/room 16 Postbus 2, 7990 AA, Dwingeloo Nederland/The Netherlands Tel.: (+31) (0)521595796 Fax : (+31) (0)521595101 -- Yan Grange Wetenschappelijk programmeur/Scientific programmer NEXPReS ASTRON het Nederlands instituut voor radioastronomie the Netherlands Institute for Radio Astronomy Radiosterrenwacht/Radio observatory Oude Hogeveensedijk 4 Paviljoen west kamer/room 16 Postbus 2, 7990 AA, Dwingeloo Nederland/The Netherlands Tel.: (+31) (0)521595796 Fax : (+31) (0)521595101
