Extract

Reaches into a map or a source-system model struct and pulls out a nested value by walking a configured key path. The result is wrapped so the rest of the graph can consume it like any other dated property. Useful right after Assign Read when the assign holds a parsed source-system record (or a plain map) and you want one field out of it.

​

Configuration

• Path — the sequence of keys to walk, applied left to right. For lists inside the path, use [] to fan out across every element.

​

Tips

• For source-system models, Extract understands the standard dated fields — start_date, end_date, id, custom_properties.
• A persisted entity (Employee, Schedule, …) stores its data in a dated-property bag, so Extract only reaches its top-level fields like id. For a mapped field use Attribute; for a raw struct read, Raw Read is the idiomatic node.
• For plain maps, both atom and string keys work without configuration.
