For LHC run 2 it has been decided to change Resources Info IoV from run-number:luminosity-block to time based (number of nanoseconds since Epoch).
Accordingly most tools have been modified to satisfy this requirement and new documentation for this service is available on the Resources Info TWiki page.
However the decision which COOL database to store Resources Info data with new IoV is not taken yet and the Web GUI is not yet updated to support new IoV.
