Input Variable in Transformation Groups in Business Rules

In Business Rules, you can transform values, e.g., you get the EXIF values and extract a specific value like geo point and transform this into a tag you can assign from a list.

You can request values from the Content, the metadata, or audit information. You request those values from implicitly defined variables. You can use these variables in transformations or actions to copy/extract/transform values and store them in another field. The implicitly defined variables are:

$$content$$ to access the Content schema data of a metadata item means the virtual item content or, e.g., Exif, IPTC, DublinCore information for files.

$$metadata$$ access to the layer schema data of a Content Item. You get access to all values from fields in assigned Layers.

$$audit$$ to access audit information like the creating user (including user details name, first name, email), modifying user (including user details name, first name, email), modification date, creation date, or information about the owner (first name, last name, email).

When setting a variable the prefix $ must not be used. Only for accessing it like here in input.

	modifiedByUser	firstName
	modifiedByUser	lastName
	modifiedByUser	emailAddress
	modifiedByUser	isDeleted
Creating User Information	createdByUser	id
	createdByUser	firstName
	createdByUser	lastName

	createdByUser	isDeleted
Owner Information	ownedByUser	id
	ownedByUser	firstName
	ownedByUser	lastName
	ownedByUser	emailAddress
	ownedByUser	isDeleted
