tip
Excerpt

The ProjectionTransformation takes all values of a list and applies the configured transformation to each item e.g. take each tag from auto-tagging and match it against the keyword list to later assign all keywords in the descriptive information. 

Example input of group: [ "Adult", "Männlich", "Male", "Erwachsen" ]

ProjectionTransformation: 

  1. TakeDictionaryValue → "Adult", 2 LookupCache → refId = 123456...

  2. TakeDictionaryValue → "Männlich", 2 LookupCache → refId = 579192...

The output of this group: [ "123456...", "579192... ]

Then you can take the refIds as expected values for AssignTagActions and tag your content with them.
