Hi, I'm trying to write a (JavaScript) script to work with the currently selected files in GC. It's simple to get the current selection like so
Now, sel is an array ("list" in AppleScript parlance) containing the file names of the selected images. If I understand the GC script dictionary correctly, almost all methods and properties are bound to the Window object and not accessible if only a file name is available.

How would I go about to (for example) set the property "IPTC credit text" (bound to Window) if all I have is a file name? If somebody knows how to do that in AppleScript, that's fine too – I'll manage to translate that.

Hi,

what do you want to script exactly?

Metadata should be changed without opening the file. This avoids recompression.

This is more an educational then a real project. I figured out how to get at the file's meta data in the mean time (although the documentation is a bit terse on that – that I have to use (in JavaScript) to get the latitude, took some experimentation).

The idea for the script was reverse geocoding (i.e. fill in the country/city IPTC fields from the GPS EXIF data). As I said, educational, since GC knows how to do that already anyway. I found a way to _get_ the data in node.js, but that is so slow that it's not practical.
