# Link Data Sources to Applications

A **data source** can be linked to an **application** only when their **asset types** are compatible. This ensures that the data provided by the data source correctly matches the context in which it will be displayed or analyzed in the application.

---

### **Asset Type Compatibility Rules**

When linking a data source to an application, the **Asset Type** of both elements must satisfy the following conditions:

1. **The asset types must either match or belong to the same domain.**
  - Example: A data source of type *Inverter* can be linked to an application of type *Solar Farm* if both belong to the same domain (e.g., Solar).
2. **A data source’s asset type cannot be a parent of the application’s asset type.**
  - This restriction prevents broader data (e.g., site-level) from being incorrectly linked to a more specific application context (e.g., equipment-level).

If these conditions are not met, the linkage will be **blocked**.

| Example | Data Source Asset Type | Application Asset Type | Result | Explanation |
| --- | --- | --- | --- | --- |
| **1** | Inverter | Inverter | ✅ Linkage possible | Exact match of asset types. |
| **2** | Inverter | Solar Farm | ✅ Linkage possible | Same domain (*Solar*). |
| **3** | Solar Farm | Solar Inverter | ❌ Linkage not possible | Data source asset type is a **parent** of the application’s asset type. |
| **4** | Solar Farm | Wind Farm | ❌ Linkage not possible | Different domains (*Solar* vs *Wind*). |

### **Summary**

- ✅ **Allowed:** Same asset type or same domain
- ❌ **Not allowed:**
  - Different domains
  - Data source asset type is a parent of the application’s asset type
