+## OData-Service 'settings'
+
+When declaring the OData-Service as our model, we have added the parameter `metadataUrlParams` like so:
+
+```json
+"sap.app": {
+    [...]
+    "dataSources": {
+      "mainService": {
+        "uri": "/here/goes/your/serviceUrl/",
+        "type": "OData",
+        "settings": {
+          "odataVersion": "2.0",
+          "localUri": "localService/metadata.xml"
+        }
+      }
+    }
+  },
+[...]
+"models": {
+      "": {
+        "dataSource": "mainService",
+        "settings": {
+          "metadataUrlParams": {
+            "sap-documentation": "heading"
+          }
+        }
+      }
+    }
+``` 
+
+This results in a GET-Request that looks like the following:
+
+```
+http://localhost:8080/here/goes/your/serviceUrl/$metadata?sap-documentation=heading&sap-language=EN 
+```
