indesign-script - Ermittlung von Metadaten von verknüpften Bildern

Auf der Suche nach einer Möglichkeit, Metadaten von verknüpften Bildern zu ermitteln, meinte ich erst per Cross-Scripting auf Bridge und dessen Möglichkeiten, Metadaten auszuwerten, zurückgreifen zu müssen: <Zugriff auf Bridge aus JavaScript für InDesign>.

Bald stellte sich heraus, dass der Zugriff auf die Metadaten auch direkt aus InDesign möglich ist.

Aus dieser Aufgabenstellung hat sich das unten stehende Skript entwickelt.
Es ermittelt diverse Metadaten (neben den Daten aus der Link-Property 'linkXmp' auch Daten nach den Schemas IPTC, Photoshop, Tiff, Exif) aus den verknüpften Bildern des aktiven Dokuments in InDesign.
Die Daten werden in eine Textdatei auf dem Schreibtisch geschrieben.
Der Name der Textdatei: 'Metadaten_' + [Name des InDesign-Dokuments] + [Suffix '.txt'] (also z.B. 'Metadaten_Unbenannt-1.txt).

Mit dem Schema CameraRaw habe ich momentan noch Schwierigkeiten.
Der Zugriff ist zwar definiert, aber ich erhalte keine Daten.
Vielleicht kann mich gelegentlich jemand auf den Haken aufmerksam machen.
