Issuing Exercise - Issue a Verified Digital Product Passport

---

💡 Create a DPP for Downstream – OEM Digital Electronic Goods Passport

💡 In this exercise, we will demonstrate how to create a Digital Product Passport (DPP) for downstream use by an OEM) in the digital electronic goods sector. A DPP is a structured digital record that stores key product information across its lifecycle, including origin, composition, environmental footprint, and repairability. This tool is designed to improve transparency, traceability, and sustainability across the supply chain. In real-world applications, OEMs can use DPPs to comply with regulatory requirements, support circular economy initiatives, and provide end users with verifiable product information.

Steps

1. Visit the Interactive VC Map - https://www.rbtp.pyx.io/interactive-vc-map

2. Select and click the OEM Product - Digital Electronic Goods Passport (DeGP)

3. Click the Digital Electronic Goods Passport (DeGP) icon, then select the 'Go to Issuing Page' button.

4. On the issuing page, update one of the input fields for the DPP:

   1. Go to the Credential Subject section and update the Name input field to your liking.
   2. For this exercise, we won't be updating the other fields, but please refer to the "Input fields description" for more details.

5. Click on “Submit” at the bottom of the page and you will have your DPP: OEM Digital Electronic Goods Passport issued.

Input fields description

• Type: specify the credential type

• Context: define the semantic meaning of properties within the credential.

• Issuer: information about the issuer person or organisation. You can modify the id and name.

• Validity period: You can specify the start and end dates for which the DPP is valid.

• Credential Subject: information about the product within the identifier scheme. You can modify the Id, Name and Registered Id.

• Id Scheme: contains the identifier scheme type, id and Name. You can modify the Id and the Name.

• Product Image: contains the product image as a URL, name and type. All these fields can be modified.

• Product Category: code representing the product class, typically using the UN CPC.

• Produced by Party: specify the information about the entity within the identifier scheme. You can modify the Id, Name and Registered Id.

• Id Scheme: information about the registration scheme. You can modify the Id and Name.

• Produced At Facility: information about the entity within the identifier scheme. You can modify the Id, Name and Registered Id.

• Dimensions: it includes Weight, Length, Width, Height, and Volume. All these fields can be modified.

• Due Diligence Declaration: contains the target resource information. All these fields can be modified.

• Materials Provenance:  details on the origin and mass fraction of components or ingredients of the product batch. You can click the “+” icon and add each component or ingredient.

• Conformity Claim: contains product conformity claims about the product / batch. You can click the “+” icon and add each conformity claim.

• Circularity Scorecard: provides a simple high-level summary of circularity performance of the product. You can modify the URL, Name and Type for the Recycling and Repair Information.

• Emissions Scorecard gives a clear snapshot of the product's greenhouse gas (GHG) emissions performance, providing a single indicator to assess its overall environmental impact. All these fields can be modified.

• Traceability Information: contains information about this traceability data set. You can click the “+” icon and add a Traceability Event and modify the Value Chain Process and Verified Ratio.

Issuing Exercise - Issue a Digital Traceability Event (DTE) and attaching multiple DPPs

💡Create a DTE for Downstream – OEM Digital Electronic Goods Passport

💡 In this exercise, we will demonstrate how to create a Digital Traceability Event (DTE) for downstream use by an OEM in the digital electronic goods sector. DTEs are collections of identifiers that specify the “what, when, where, why and how” of the products and facilities that constitute a value chain. For example, for the above exercise of creating the OEM DPP of a Generic Laptop, the DTE we are going to issue in this exercise specifies the “what” products that creates the Generic Laptop DPP. In this example, the products are also DPPs for components of the laptops (e.g. battery, screen, keyboard, and casing).

You can also try creating the DPPs for the 4 components and once we have all 4 components DPPs, we are going to attach them to the DTE

Steps

1. Take note of all the DPPs IDR Link. You can use the default DPP in the Interactive VC Map.

   1. Copy the link to the Sample Issued Credential

2. Go to the OEM - DTE: Association Issuing Page

3. Scroll to the bottom of the Issuing Page and go to the Child EPC List section.
   The Child Electronic Product Code (EPC) are list of items (can be a DPP) that constructs the parent EPC (which in this example is the Generic Laptop Electronic Goods Passport)

   1. Add all the components to the list. Fill in the ID and the Name accordingly
   2. If the Child EPC consist of multiple items, you can use the next section (Child Quantity List) to specify the quantity used.

4. Once inputted, click on submit to issue the DTE and you can see the issued DTE similar to the following
