HamQTH.com's XML, in addition to sending a new QSO, also allows to update or delete an existing QSO. Is there any hope of implementing this in Log4om?
Update existing QSO
To specify the QSO you want to update in the database, you have to post old values of qso date, time on, callsign and mode. Without these values server won't be able to find your QSO and update it. Old values are also part of ADIF ouput but with OLD_ prefix - OLD_QSO_DATE, OLD_TIME_ON, OLD_CALL, OLD_BAND, OLD_MODE. E.g. you want to update name in the QSO, send only all mandatory fields (OLD_QSO_DATE etc.) and NAME field.
Delete QSO
Specify QSO to delete using OLD_QSO_DATE, OLD_TIME_ON, OLD_CALL, OLD_BAND and OLD_MODE field in ADIF output.
