The XMP inject default Switch app can be used for two main purposes:
- Inject an external dataset into the job
The data to be injected is linked to the incoming job as an external dataset and corresponds to the XMP schema which is listed in the Switch jobticket.
For example, the dataset could have been created by the export metadata mechanism which extracts information from a PDF.
A scenario where we can use this feature is when merging information from multiple PDFs into a single PDF.
- Insert or update data to an existing XMP dataset
All kinds of Switch variables can be injected as data. For example, we can use this feature in a GWG Ad Ticket to update the missing values.
