FOIA is all of your records of checks that are made with the FAA, applications for ratings, etc. This has been pretty standard for 121 airlines for years, but there were a few exceptions. It was not required by the PRIA law and AC, but it was recommended in the AC.
Moving forward, PRD will contain all records of training (that are PRIA reportable), for the entirety of your career, in addition to FAA PRD information. I'm not sure if there's a software feature to only display the last 5 years, but more than 5 years can and is being entered, since we are moving forward and all new training/checking records are required to be reported. There will likely be no FOIA in the short future, but we are in the transition phase and airlines are being advised to do both PRIA and PRD, because not all carriers have data in the PRD yet. PRIA is set to sunset.
