Configuration
- System integration — which integration’s metadata to read.
- Source — which metadata catalogue (titles, departments, …). Source picker is filtered to the chosen integration’s system.
- Pattern field / Value field — which canonical field of each
record (
value,code,readable_name,description) becomes the regex pattern, and which becomes the output value. - Caseless / Confined / Loose — same toggles as the static Mapping node’s paste dialog. Loose tolerates dashes, whitespace, dots, slashes, and ampersands.
- Output type — the property type the output value is cast to.
- On unmatched — what to do when an input doesn’t match any metadata row: emit a configured fallback value, or raise a generic Twine anomaly that surfaces in PropertyMapping reporting.
- Nil handling — what to do when this node produces a nil value (anomaly-mode unmatch, or a fallback that casts to nil): include it, skip all such mapping-produced nils, or skip just the trailing (most-recent) ones. Upstream nils always pass through.
