How to Set Up Schema Lineage to the Data Model
Step-by-step guide to mapping schema fields to entity properties in the data model for full data traceability in NeoArc Studio.
Schema lineage connects schema fields to entity properties in the data model (model.neoarc). This guide walks through the process of setting up lineage mappings so that every schema field traces back to its canonical source in the model.
Prerequisites
- A schema definition with fields
- A data model (
model.neoarc) with entities and properties defined
Step 1: Open the Schema
Step 2: Select a Field
Step 3: Open the Lineage Panel
The Lineage tab displays all existing lineage entries for the selected field. If no entries exist, the panel shows an empty state with an Add Entry button.
Step 4: Add a Lineage Entry
Step 5: Pick the Target Entity and Property
Step 6: Save
Step 7: Verify in the Intent Graph
Lineage Overrides for Inherited Fields
When using schema inheritance, derived schemas may need different lineage mappings than the parent schema for inherited fields.
