Extract

Reaches into a struct or map 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 whole record (an Employee, a Schedule, a step result) and you only 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 richer entities (Employee, Schedule, etc.), Extract understands the standard dated-property fields — start_date, end_date, id, custom_properties.
• For plain maps, both atom and string keys work without configuration.
