Export custom metadata

Question

Does anyone know a way of exporting custom metadata in Aperture? The standard export only seems to apply to ITPC data.

Answer 1

RedKite provided this script for exporting to a tab-delimited text file in an archived forum. Copy the script to the Apple script editor. Change "category" in the upper section and "photo category" in the lower section to the name of your custom field. Run it. To add more custom fields, copy and paste the custom field section in the lower part. Add a corresponding line to the upper part. The upper part is the column name on the spreadsheet.
This script is old, It works for the version name, file name, and custom fields. It does not work for Keywords (written into the script) or other IPTC fields written the same way. Does anyone know a script that does both IPTC and custom fields in Aperture 3 in 2013?
tell application "Aperture"
set tSelection to the selection
-- this is the header, not really necessary
set tValues to "Version Name" & tab
set tValues to tValues & "File Name" & tab
set tValues to tValues & "Keywords" & tab
set tValues to tValues & "Category" & tab
set tValues to tValues & return
--here starts the real stuff
repeat with i from 1 to number of items in tSelection
set tImg to item i of tSelection
--add Version name
try
set t to name of tImg
on error
set t to ""
end try
set tValues to tValues & t & tab
try
--add FileName
set t to the value of other tag "FileName" of tImg
on error
set t to ""
end try
set tValues to tValues & t & tab
try
--add IPTC tag
set t to the value of IPTC tag "Keywords" of tImg
on error
set t to ""
end try
set tValues to tValues & t & tab
try
--add a custom field
set t to the value of custom tag "Photo Category" of tImg
on error
set t to ""
end try
set tValues to tValues & t & tab
--next line/image
set tValues to tValues & return
end repeat
set f to choose file name with prompt "Choose file name..."
set my_log to tValues
set mylogfile to open for access f with write permission
set eof of mylogfile to 0
write my_log to mylogfile starting at eof
close access mylogfile
end tell
