A table can have multiple link columns, and each link can have multiple lookup columns. --- ## 📐 UI Data Types - **LINK** — Special column used to represent inter-table relations - **LOOKUP** — Special column used to project associated table fields via a link --- ## 🔗 LINK Semantics A LINK column stores metadata for: - `tableId` — Current table - `associatedTableId` — Associated (linked) table - `relationType` — Type of relationship - `linkColumnId` — Link column identifier **Supported relation patterns:** | Pattern | Description | |---|---| | `ONE_TO_ONE` | Each record in the source maps to one record in the destination | | `ONE_TO_MANY` | One source record maps to many destination records | | `MANY_TO_MANY` | Many source records map to many destination records | --- ## 🔍 LOOKUP Semantics - A LOOKUP column is tightly coupled with a specific LINK column - References a link using `linkColumnId` - Represents a selected column from the associated table - Multiple lookup columns can be defined for the same link --- ## 🗂️ Metadata in `ColumnDTO.colOptions` Use `colOptions` to persist link/lookup metadata. | Field | Description | |---|---| | `columnId` | Current column ID | | `tableId` | Current table ID | | `associatedTableId` | Associated table ID | | `linkColumnId` | Link column ID — used by LOOKUP; references the LINK column's `columnId` | | `relationType` | Relation semantics for LINK | --- ## 🔄 Manual Linking Record Flow To create manual record-level links: 1. Fetch associated table schema/data 2. User selects associated record(s) to link 3. Send linking payload with: - `sourceRecordId` — PK of the current table row - `destinationRecordId` — PK of the associated table row - `linkColumnId` — LINK column identifier 4. Backend resolves link metadata from `linkColumnId` (relation type, associated table, direction/constraints) 5. Backend applies relation rules and stores the link relation --- ## 📋 Record Linking Contract | Field | Description | |---|---| | `sourceRecordId` | PK of the current table row | | `destinationRecordId` | PK of the associated table row | | `linkColumnId` | LINK column identifier | | `tableId` | Current table ID | > Backend derives all remaining relation metadata from the link configuration. --- ## ⚠️ Important Notes > - LINK and LOOKUP are **column-level constructs** first; record linking is a data-level operation built on top > - LOOKUP behavior depends on LINK existence and metadata integrity > - With multiple links to the same associated table, each LOOKUP must bind to the correct `linkColumnId` > - Always treat the associated row ID as the associated table PK for linking UI selection paths: /noCo/api/v2/workspaces/{workspaceId}/extraction/{extraction_id}: parameters: - name: workspaceId in: path required: true schema: type: string example: '{{workspaceId}}' - name: extraction_id in: path required: true schema: type: string example: '{{extractionId}}' put: tags: - AI Extraction summary: Update Extraction description: |- ## 1️⃣ Overview **Purpose:** Updates an existing extraction configuration.
