Observation
GET /udl/ionoobservation/tuple
Changed onService operation to dynamically query data and only return specified columns/fields. Requested columns are specified by the 'columns' query parameter and should be a comma separated list of valid fields for the specified data type. classificationMarking is always returned. See the queryhelp operation (/udl/<datatype>/queryhelp) for more details on valid/required query parameter information. An example URI: /udl/elset/tuple?columns=satNo,period&epoch=>now-5 hours would return the satNo and period of elsets with an epoch greater than 5 hours ago.
