# SurfaceRelationPolicy · types

   
                                      
                                                                                
                                               
                  
           
          
   

The following types define named objects and their relationships. Tables include inherited properties. Schema-derived types refer to their validated structures; a TypeScript declaration does not replace the compiler’s semantic checks.

## SurfaceRelationPolicy

One versioned relation declaration shared by compiler admission and native mutation.

```typescript
export type SurfaceRelationPolicy = z.infer<typeof surfaceRelationPolicySchema>;
```

## Applied examples : One client, many quotes

The constraint governs links; the presentation group shows four results and access to the full list.

### Configuration

Fragment placed in `relationPolicies[]`. [Properties and accepted values](https://developers.dagio.ai/reference/surface-relation-policy/).

```json
{
  "contract": "SurfaceRelationPolicy@1",
  "key": "quote-client",
  "linkTypePath": "application/client",
  "source": {
    "definitionPaths": [
      "workspace/quotes/surface/quote"
    ],
    "fields": []
  },
  "target": {
    "definitionPaths": [
      "workspace/clients/surface/client"
    ],
    "fields": []
  },
  "maximumOutgoing": 1,
  "maximumIncoming": null,
  "acyclic": false,
  "deletion": "forbid",
  "maximumTraversalNodes": 1000
}
```

### Variation and connection

Fragment placed in `presentation.recordProfiles[].detail.relatedGroups[]`. [Properties and accepted values](https://developers.dagio.ai/reference/workspace-record-profile/).

```json
{
  "key": "quotes",
  "label": "Quotes",
  "queryBindingKey": "client-quotes",
  "maximumVisible": 4,
  "openAllLabel": "View all quotes",
  "rowIcon": null
}
```

### UI layout example

The illustrative layout below places this configuration in the Clients/Quotes app. Insert each fragment at the stated location, with Field, Query and Action references matching the Model declarations.

1. Selected client
2. Search
3. Quotes
4. View all quotes
