1: Check of integration "metadata-read"​

Extracting the ExifTool:ExifToolVersion metadata allows to ensure that the metadata-read. integration is functional. The metadata ExifTool:ExifToolVersion in always returned by exiftool.

Attribute(s) definition(s) ...​

  • exiftoolVersion: text ; [ ] multi ; [ ] translatable

    • read from metadata (first found wins):
    [

9: First metadata set, with alternate value (1)​

for this test, only the metadata IPTC:City is set.

Attribute(s) definition(s) ...​

  • City: text ; [ ] multi ; [ ] translatable
{{ file.getMetadata('XMP-iptcCore:CreatorCity').value ?? file.getMetadata('IPTC:City').value ?? 'no-city ?' }}

metadatavalue(s)
IPTC:CityParis

... set attribute(s) initial value(s)​

Attributesinitial value(s)

10: First metadata set, with alternate value (2)​

for this test, no metadata is set, so the default value is used.

Attribute(s) definition(s) ...​

  • City: text ; [ ] multi ; [ ] translatable
{{ file.getMetadata('XMP-iptcCore:CreatorCity').value ?? file.getMetadata('IPTC:City').value ?? 'no-city ?' }}

11: Many metadata to a mono-value attribute​

Here an array [a, b] is used, the join filter inserts a " - " only if required.

Attribute(s) definition(s) ...​

  • CreatorLocation: text ; [ ] multi ; [ ] translatable
{{ [file.getMetadata('XMP-iptcCore:CreatorCity').value, file.getMetadata('XMP-iptcCore:CreatorCountry').value] | join(' - ') }}

... with file metadata ...​

metadatavalue(s)
XMP-iptcCore:CreatorCityParis
XMP-iptcCore:CreatorCountryFrance

... set attribute(s) initial value(s)​

Attributesinitial value(s)
CreatorLocationParis - France

12: Many metadata to a multi-values attribute​

nb: We fill an array that will be joined by \n to generate one line per item (required).

The merge filter requires arrays, so IPTC:Keywords defaults to [] in case there is no keywords in metadata.

Attribute(s) definition(s) ...​

  • Keywords: text ; [X] multi ; [ ] translatable
{{ ( (file.getMetadata('IPTC:Keywords').values ?? []) | merge([file.getMetadata('IPTC:City').value, file.getMetadata('XMP-photoshop:Country').value ]) ) | join("\n") }}

... with file metadata ...​

metadatavalue(s)

IPTC:CityParis

... set attribute(s) initial value(s)​

Attributesinitial value(s)

13: Transform code to human readable text​

here the ExposureProgram metadata is a code (0...9), used to index an array of strings.

Attribute(s) definition(s) ...​

  • ExposureProgram: text ; [ ] multi ; [ ] translatable
{{ [ 'Not Defined', 'Manual', 'Program AE', 'Aperture-priority AE', 'Shutter speed priority AE', 'Creative (Slow speed)', 'Action (High speed)', 'Portrait', 'Landscape',  'Bulb' ][file.getMetadata('ExifIFD:ExposureProgram').value] ?? 'Unknown mode' }}

... with file metadata ...​

metadatavalue(s)
ExifIFD:ExposureProgram2

... set attribute(s) initial value(s)​

Attributesinitial value(s)
ExposureProgramProgram AE

14: Read from metadata: first tag found wins​

The readFromMetadata list is evaluated in order; the first tag present in the file metadata is used. Here XMP-iptcCore:CreatorCity is absent, so IPTC:City is used.

Attribute(s) definition(s) ...​

  • City: text ; [ ] multi ; [ ] translatable

    • read from metadata (first found wins):
    [
        "XMP-iptcCore:CreatorCity",
        "IPTC:City"
    ]

... with file metadata ...​

metadatavalue(s)

15: Read from metadata into a multi-values attribute​

Attribute(s) definition(s) ...​

  • Keywords: text ; [X] multi ; [ ] translatable

    • read from metadata (first found wins):
    [
        "XMP-dc:Subject",
        "IPTC:Keywords"
    ]

... with file metadata ...​

metadatavalue(s)
IPTC:Keywordsdog ; cat ; bird

... set attribute(s) initial value(s)​

16: Read from metadata: no tag found​

When none of the listed tags is present, no attribute is created.

Attribute(s) definition(s) ...​

  • City: text ; [ ] multi ; [ ] translatable

    • read from metadata (first found wins):
    [
        "XMP-iptcCore:CreatorCity",
