Document Metadata

The <Metadata> section inside <Document> sets PDF information fields that are embedded in the output file.

Note

Only the six string fields below are currently wired up from Craft Language XML. <CreationDate>/<ModificationDate>/<Trapped>/ <GtsPdfx>/<AutoKeywords> are silently skipped by the parser today — they are not parse errors, they simply have no effect. The underlying DocraftDocumentMetadata C++ type does support dates, trapping, and GTS-PDFX (see Types & Enums); there is currently no automatic keyword extraction utility in the codebase at all. If you need any of these, set them from C++ via DocraftLoomPdfCreator::set_metadata() (see Getting Started) rather than from the .craft file.
