Copy the actual json response and paste it into the notepad editor. You will need the values later.
- Search for the `submodelDescriptors` array. We need to add more elements to the submodelDescriptors array.

### Update Digital Twin
- Copy your response and add the following json content into the submodelDescriptors array:

Attach the following **SingleLevelBOMAsBuilt** and **SerialPart** aspects to the existing Digital Twin object that you retrieved and substitute the corresponding placeholders **<BOMAsBuiltID<BOMAsBuiltID>>** and **<SerialPart<SerialPart>>** with their Ids generated in [step 1](#1-generate-the-ids).
- Substitute the corresponding placeholders **<BOMAsBuiltID<BOMAsBuiltID>>** and **<SerialPart<SerialPart>>** with their Ids generated in [step 1](#1-generate-the-ids).

Example to find the placeholders:

1 - Get access to the file [example-dt-irs](./resources/digital-twins/example-dt-irs.json)
> [!IMPORTANT]
> `<EDC_CONTROLLANE_URL>` and `<EDC_DATAPLANE_URL>` are given in a paper
2 - Get the placeholders from the below table and search with CTRL + F in [example-dt-irs](./resources/digital-twins/example-dt-irs.json):
> [!CAUTION]
> Please make sure that you substitute all the placeholders with their values
3 - Substitute the following placeholders with their values. The values you will get them from the existing digital twin object that was retrieved.
- Search for the `supplementalSemanticId` keyword (if any) and remove that line.

- Save your changes to a json file.

| Placeholder | Path |
|------------------------- |-----------------------------------------------------------------|
| <digitalTwinId<digitalTwinId>> | globalAssetId |
| | id |
| <PART_NAME> | idShort |
| <YOUR PART INSTANCE ID<y>> | specificAssetIds[1].value |
| <EDC_DATAPLANE_URL> | submodelDescriptors[0].endpoints[0].protocolInformation.href |
| | submodelDescriptors[1].endpoints[0].protocolInformation.href |
| | submodelDescriptors[2].endpoints[0].protocolInformation.href |
| <digitalTwinSubmodelId<y>> | submodelDescriptors[0].endpoints[0].protocolInformation.href |
| | submodelDescriptors[0].id |
| <EDC_CONTROLPLANE_URL> | submodelDescriptors[0].endpoints[0].subprotocolBody |
| | submodelDescriptors[1].endpoints[0].subprotocolBody |
| | submodelDescriptors[2].endpoints[0].subprotocolBody |
| <BOMAsBuiltID<BOMAsBuiltID>> | submodelDescriptors[1].endpoints[0].protocolInformation.href |
| | submodelDescriptors[1].id |
| <serialPartID<serialPartID>> | submodelDescriptors[2].endpoints[0].protocolInformation.href |
| | submodelDescriptors[2].id |

> [!TIP]
> The table shows number of occurences of a specific property, for example <digitalTwinId<y>> has two occurences: `globalAssetId` and `id`
### Update Digital Twin with BOMAsBuilt and SerialPart Submodels

Update the digital twin submodel using the following command:

> [!CAUTION]
> Please make sure that you substitute all the placeholders with their values from the above table
> PUT /shell-descriptors/<DIGITAL_TWIN_ID_BASE64_ENCODED>
> Please only use your assigned UUID from [here](./resources/test-data/carParts.json) that matches the UUID on the given paper
*Windows*
<details>
<summary>Click to see the Windows command</summary>

4 - Save your modified digital twin in json format.
```bash
curl.exe -v -X PUT "<DIGITAL_TWIN_REGISTRY_URL>/shell-descriptors/<DIGITAL_TWIN_ID_BASE64_ENCODED>" `
-H "Content-Type: application/json"
--data-binary "@<YOUR_JSON_FILE>.json"`"
```
Now, you can update the modified digital twin object using the following command:
</details>
> PUT /shell-descriptors/<DIGITAL_TWIN_ID_BASE64_ENCODED>
*Mac & Linux*
<details>
<summary>Click here to see the Mac & Linux command</summary>
```bash
curl --location --request PUT '<DIGITAL_TWIN_REGISTRY_URL>/shell-descriptors/<DIGITAL_TWIN_ID_BASE64_ENCODED>' \
--header 'Content-Type: application/json' --data '@resources/<YOUR_DT_JSON>.json'
curl --location '<DIGITAL_TWIN_REGISTRY_URL>/shell-descriptors/<DIGITAL_TWIN_ID_BASE64_ENCODED>' \
--header 'Content-Type: application/json' \
--data "@<YOUR_JSON_FILE>.json"
```
</details>
Congratulations, you have successfully attached BOMAsBuilt relationships and serial part to the existing Digital Twin object.
