I note that there are now quite a few loggers and other programs that import the WWFF list and provide lookup facilities within a third party application. The only download format for the entire WWFF directory seems to be PDF, and only a small subset of database fields are available.
It would provide significant extra functionality in these 3rd party applications, and probably encourage activity in WWFF, if the entire database, all fields, was downloadable in either XML or CSV format.
