CX-0118 Delivery Information Exchange 2.0.0

ABSTRACT

Delivery Information plays a crucial role in proactively tracking, managing, and assessing the timely fulfillment of customer orders from various suppliers in order to avoid shortages and bottlenecks. Relying on manual methods like phone calls, or email correspondence to collect this data can introduce errors, does not include last-minute or real-time updates, and can potentially cause shortages.

One effective strategy to address these challenges involves the sharing of Delivery Information among Catena-X business partners in an interoperable manner. Establishing a standardized semantic definition to describe delivery information and a common API is a fundamental step to enable this exchange and foster compatibility, thereby maximizing the range of solutions available for mitigating any potential supply shortages.

New Content:

• added a note on the obligation of standard implementers to make aware that sensitive data is being handled, see [Chapter 2.1.3].

1 INTRODUCTION

In a typical order-based manufacturing and delivery process, a customer places an order, and a supplier undertakes the task of fulfilling it. Delivery Information encompasses two main categories: logistics details and delivery metrics. Logistics details cover when and where products are shipped, as well as the quantities involved. Delivery metrics differentiate between estimated and actual departure and arrival times, e.g. for outbound deliveries from a supplier's factory and inbound deliveries to a customer's factory.

Monitoring and handling Delivery Information effectively between suppliers and customers plays a crucial role in optimizing the delivery processes. Early detection and resolution of delivery-related issues hinge on the continuous tracking of this information. However, relying on manual communication methods, like phone calls or emails, introduces the risk of errors and consumes valuable time. Existing ERP system interfaces, primarily tailored for order planning, might not comprehensively cover the exchange of Delivery Information.

To facilitate efficient exchange, it is essential to establish a standardized and semantically defined description of Delivery Information. Standardizing semantics and exchange protocols enables participants in the supply chain to share Delivery Information in an interoperable manner.

The proposed model includes information about departure and arrival dates, times, locations, shipped quantities, tracking number, and other relevant logistics-related information that helps in coordinating and ensuring the smooth planning of product deliveries to their intended destination. It allows businesses to better plan and execute deliveries, minimize delays, and optimize their delivery processes, stock and production planning, avoiding shortages and increasing efficiency.

1.1 AUDIENCE & SCOPE

This section is non-normative

This document describes the Delivery Information semantic model used in the Catena-X network and the associated API for exchanging Delivery Information. This standard is relevant for the following roles defined in [CX-OMW]:

• Data Providers willing to provide Delivery Information data
• Data Consumers interested in requesting and receiving Delivery Information data
• Business Application Providers interested in providing solutions implementing this standard
• Consulting Services Providers interested in supporting companies fulfilling the standard

The scope of this standard is only the Delivery Information aspect model and API. It describes the exchange of Delivery Information data through a connector in accordance with [CX-0018].

1.2 CONTEXT AND ARCHITECTURE FIT

This section is non-normative

In a typical item procurement process, a customer initiates an order, and a supplier undertakes the task of fulfilling it. As part of this process, the Delivery Information typically refers to data or details regarding when, where and in which quantities of products or goods are shipped or are expected to be shipped. It includes information about estimated and actual delivery dates, times, locations, shipped quantities, and other relevant logistics-related information that helps in coordinating and ensuring the smooth delivery planning of product deliveries to their intended destination.

Within the framework of the Catena-X network, this standard defines the DeliveryInformation aspect model. Its purpose is to establish a consistent and uniform interpretation and handling of Delivery Information among all interested parties, ensuring that this data is understood and managed in the same manner by all stakeholders.

Figure 1 shows the high-level architecture of the Delivery Information exchange in the Catena-X dataspace and the services that are involved. Both the data provider and the data consumer must be members of the Catena-X network in order to communicate with each other. With the help of the Credential Service and the Identity Access Management (IAM) each participant can authenticate itself, verify the identity of the requesting party and decide whether to authorize the request. The Delivery Information data is provisioned in accordance with [CX-0002].

1.3 CONFORMANCE AND PROOF OF CONFORMITY

This section is non-normative

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative. The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document are to be interpreted as described in [BCP 14] [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. All participants and their solutions will need to prove, that they are conform with the Catena-X standards.

All participants and their solutions will need to prove, that they are conform with the Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs). The proof of conformity for a single semantic model is done according to the general rules for proving the conformity of data provided to a semantic model or the ability to consume the corresponding data. Furthermore, participants agree to follow the normative language of this standardization document and to implement the required API-Endpoints described in Chapter 4.

1.4 EXAMPLES

The JSONs snippets below provide an example of the value-only serialization of the "DeliveryInformation" aspect model for three different delivery situations:

1. A not yet departed delivery - estimated departure and arrival dates
2. A delivery in transit - actual departure and estimated arrival dates
3. A delivery with actual arrival times- actual departure and arrival dates

Note: Delivery values are located in the transitEvents of the delivery.

1. The order has not yet departed from its origin, as indicated by the estimated values for both departure and arrival. This is an example of estimated delivery.

Actual time	-	Refers to the specific, real-time date and time when an event occurs during delivery.
Estimated time	-	Refers to a projected or estimated time for an event or occurrence, based on calculations or predictions, rather than the exact, confirmed time.
Origin	-	Is the starting point from which goods are dispatched or shipped to.
Destination	-	Is the final location where the goods are to be delivered or received.
Delivery Information	-	Provides an overview of related shipments, tracking the movement of goods and associated order details, not the physical shipment. It may represent a full shipment or a portion, like a container with varied commodities.
Customer	-	The recipient of products ordered from / manufactured by a supplier.
Supplier	-	The supplier / manufacturer of a product.
Identity Access Management	IAM	IAM is a security system that regulates who can access an organization's information and systems, ensuring only authorized individuals have the right level of access to prevent unauthorized entry and protect against security risks.
Digital Twin	DT	Digital representation of an asset that provides data on aspects of the represented data following [CX-0002].
decentralized Digital Twin Registry	dDTR	Component providing registration and discovery API implementations following [CX-0002]. Sometimes referred to without the "decentralized" BUT in Catena-X those are always decentralized.
Asset Administration Shell	AAS	Technical concept for Digital Twins consisting of different standards. Application in Catena-X is described in Digital Twins in Catena-X standard [CX-0002]
Shell Descriptor		Technical concept of the AAS API describing metadata of an Asset Administration Shell representing a Digital Twin. It holds several identification information and metainformation about which submodels are available and where to get the data from (see [CX-0002], IDTA-01002-3-0). There may exist multiple Shell Descriptor for the same represented Asset (see [CX-0126]).
Submodel Descriptor		Technical concept of the AAS API describing metadata of Submodels within a Shell Descriptor (Asset Administration Shell) (see [CX-0002], IDTA-01002-3-0).

2.1.2 DATA REQUIRED

No additional data requirements.

2.1.3 ADDITIONAL REQUIREMENTS

CONVENTIONS FOR USE CASE POLICY IN CONTEXT DATA EXCHANGE

In alignment with our commitment to data sovereignty, a specific framework governing the utilization of data within the Catena-X use cases has been outlined. A set of specific policies on data offering and data usage level detail the conditions under which data may be accessed, shared, and used, ensuring compliance with legal standards.

For a comprehensive understanding of the rights, restrictions, and obligations associated with data usage in the Catena-X ecosystem, we refer users to

• the detailed ODRL policy repository [CX-ODRL]. This document provides in-depth explanations of the terms and conditions applied to data access and utilization, ensuring that all engagement with our data is conducted responsibly and in accordance with established guidelines.
• the ODRL schema template. This defines how policies used for data sharing/usage should get defined. Those schemas MUST be followed when providing services or apps for data sharing/consuming.

ADDITIONAL DETAILS REGARDING ACCESS POLICIES

A Data Provider may tie certain access authorizations ("Access Policies") to its data offers for members of Catena-X and one or several Data Consumers. By limiting access to certain Participants, Data Provider maintains control over its anti-trust obligations when sharing certain data. In particular, Data Provider may apply Access Policies to restrict access to a particular data offer for only one Participant identified by a specific business partner number:

• Membership
• BPNL

ADDITIONAL DETAILS REGARDING USAGE POLICIES

In the context of data usage policies (“Usage Policies”), Participants and related services MUST use the following policy rules:

• Use Case Framework (“FrameworkAgreement”)
• at least one use case purpose (“UsagePurpose”) from the above mentioned ODRL policy repository.

Additionally, respective usage policies MAY include the following policy rule:

• Reference Contract (“ContractReference”).

Details on namespaces and ODRL policy rule values to be used for the above-mentioned types are provided via the ODRL policy repository [CX-ODRL].

REMINDER OF ANTITRUST

Notice and/or acknowledgement concepts to raise awareness of antitrust issues during use of this standard are RECOMMENDED, for example through the implementation of a helpdesk or pop-up info.

2.1.4 DIGITAL TWINS AND SPECIFIC ASSET IDs

This standard builds upon the Industry Core Part Type [CX-0126] and the Digital Twins in Catena-X [CX-0002] standards. It follows the following design patterns:

• Usage of Digital Twins as shared assets to follow a pull approach for data.
• Usage of the specific asset IDs and further identification data for the Digital Twin for the Part Type (see [CX-0126]).
• Provisioning of the PartTypeInformation on supplier side (see [CX-0126]).

Because both parties may provide data regarding different aspects of the same Part Type Twin, they need to use the same identification data to pinpoint it.

• The supplier of the part has a Digital Twin representation and is then able to offer Delivery Information data to customers.
• The customer, who orders or uses the part, has a Digital Twin representation to offer Delivery Information data to a supplier.
• Both twins refer to the same asset and provide complementary information. They share the same identification data in two partners' context.
  • The supplier
    • MUST create the Digital Twin first.
    • MUST generate the Catena-X ID and ensure that the customer-specific asset IDs and submodel descriptors are only accessible by the specific customer.
    • MAY use the Digital Twin for multiple customers.
  • The customer
    • MUST create one Digital Twin per supplier.
    • MUST use the Catena-X ID generated by the supplier.

The definition of identification data (Catena-X ID, Asset Administration Shell ID, specific asset ID) MUST follow the Industry Core Part Type [CX-0126]. Refer to Chapter 4.1.2 for further details.

Note: The Part Type Twin's data is considered sensitive. Data providers MUST implement appropriate measures ensuring that competitors-specific asset IDs and/or information about submodels is accessible only to the data consumers it concerns, but not to their competitors.

Figure 2 shows how the shared asset approach is realized. The orange lines show which submodels belong to the respective AAS. All Delivery Information specific submodels are bound to the specific Part Type's context e.g., meaning that the Delivery Information aspect is described for the specific catalog item on supplier and customer side represented by the AASs. The orange submodels are the submodels used within this standard's context. The grey submodels are used within the Industry Core [CX-0126](PartTypeInformation, SingleLevelBomAsPlanned, SingleLevelUsageAsPlanned). The blue dashed lines show the references between DTs based on Catena-X UUIDs and BPNL information that may be resolved by the Item Relationship Service (see [CX-0126]).

Figure 2: Conceptual levels of provisioning digital twins in the shared asset approach.

Figure 2 details two conceptual levels:

• The Asset level contains the asset (Industry Core Part Type) represented by a Digital Twin. The latter is provisioned as an Asset Administration Shell (AAS) within the decentralized Digital Twin Registry (dDTR) of the data provider (supplier or customer).
• The Submodel level represents the actual information that are held by a Digital Twin (DT). Those submodels follow the respective definition of the Semantic Aspect Meta Model (SAMM) format (see Chapter 3). The dDTR only holds meta information about the Submodel (e.g. kind of submodel via semantic ID or connector endpoint information).

Note: Delivery information can be conveyed in both directions from Supplier to Customer and Customer to Supplier.

3 ASPECT MODELS

This section is normative

3.1 ASPECT MODEL "DELIVERY INFORMATION"

3.1.1 INTRODUCTION

The Delivery Information semantic model defines the data and details regarding when and how products or goods are scheduled to be delivered and actually delivered from one location to another. It includes information about order positions, material numbers and deliveries (quantity, status of the delivery and location of the delivery). It may include tracking number and incoterms as well. For the complete semantics and detailed description of its properties refer to the SAMM model in Chapter 3.1.5.1.

3.1.2 SPECIFICATIONS ARTIFACTS

The modeling of the semantic model specified in this document was done in accordance to the "semantic driven workflow" to create a submodel template specification [SMT].

This aspect model is written in SAMM 2.1.0 as a modeling language conformant to [CX-0003] as input for the semantic-driven workflow.

Like all Catena-X data models, this model is available in a machine-readable format on GitHub conformant to [CX-0003].

3.1.3 LICENSE

This Catena-X data model is made available under the terms of the Creative Commons Attribution 4.0 International (CC-BY-4.0) license, which is available at Creative Commons.

3.1.4 IDENTIFIER OF SEMANTIC MODEL

The semantic model has the unique identifier

urn:samm:io.catenax.delivery_information:2.0.0

This identifier MUST be used by the data provider to define the semantics of the data being transferred.

3.1.5 FORMATS OF SEMANTIC MODEL

3.1.5.1 RDF TURTLE

The RDF turtle file, an instance of the Semantic Aspect Meta Model, is the master for generating additional file formats and serializations. It can be found under the following link:

https://github.com/eclipse-tractusx/sldt-semantic-models/blob/main/io.catenax.delivery_information/2.0.0/DeliveryInformation.ttl

The open source command line tool of the Eclipse Semantic Modeling Framework is used for generation of other file formats like for example a JSON Schema, aasx for Asset Administration Shell Submodel Template or a HTML documentation.

3.1.5.2 JSON SCHEMA

A JSON Schema can be generated from the RDF Turtle file. The JSON Schema defines the Value-Only payload of the Asset Administration Shell for the API operation "GetSubmodel".

3.1.5.3 AASX

An AASX file can be generated from the RDF Turtle file. The AASX file defines one of the requested artifacts for a Submodel Template Specification conformant to [SMT].

4 APPLICATION PROGRAMMING INTERFACES

This section is normative

4.1 API USED TO EXCHANGE "DELIVERY INFORMATION"

As described in Chapter 2.1.4 this standard builds upon the [CX-0002] Digital Twins in Catena-X and [CX-0126] Industry Core Part Type standards. Therefore, the APIs provided by the Digital Twin standard are combined with the part identification defined in the Industry Core standard. This chapter defines how the aforementioned standards and the [CX-0018] standard MUST be used to facilitate the provisioning of Delivery Information data. The usage of the Discovery Services defined in [CX-0001], [CX-0053] is not mandatory, because this standard assumes an already existing business relationship between the involved parties.

The sequence diagram in Figure 3 provides an overview of the interactions required to register the Part Type Twin following the shared asset approach.

• Steps 1 & 2: Register the dDTR access for the partner at the connector
• Steps 3 & 4: When using the repository pattern, create the submodel (and twin)
• Steps 5 & 6: Register the submodel endpoint for the partner at the connector
• Steps 7 & 8: Register or update the twin Shell Descriptor relying on the registered Connector asset for the submodel endpoint and the identification data of the partners.

Note: This sequence diagram is simplified and does not cover the generation of the Part Type Twin on supplier side and the handling of the identification data needed. Both partners need to create a Part Type Twin of the shared asset as well as provide Delivery Information data.

Figure 3: Flow to create and register a digital twin

The sequence diagram in Figure 4 provides an overview of the interactions required when a customer (acting as data provider) provisions Delivery Information data to a supplier (acting as data consumer).

The flow "Supplier reads (updated) Submodel from Customer" visualizes the sequence of calls when consuming data:

• Steps 3 - 8: Contract dDTR usage in the connector.
• Steps 9 - 12: Lookup the Industry Core Part Type Twin for a Part Type based on the common identification data.
• Steps 13 - 18: Read the Shell Descriptor of the Industry Core Part Type Twin to extract the Delivery Information submodel endpoint (registered at the connector).
• Steps 19 - 24: Contract the Delivery Information data usage in the connector.
• Steps 25 - 29: Consume and use the Delivery Information data.

Figure 4: Flow to lookup a digital twin and get a submodel.

Note: Depending on the use of repository patterns and the design of the Digital Twins, the data may be updated manually in the Submodel endpoint.

4.1.1 CONNECTOR DATA ASSET STRUCTURE

The endpoints for the dDTR and the Submodel Endpoint MUST be made available BUT they MUST NOT be directly called data consumer. Rather, for access to dDTRs and Submodels, there MUST be contracts negotiated in accordance with the DSP. Therefore, the endpoints MUST be offered as connector data assets. To make these assets easily identifiable in the connector's catalog, each asset MUST be configured with a set of properties as described in the corresponding sections below.

The following table provides an overview of the connector data assets that the parties MUST offer to be able to provision and/or consume Delivery Information data.

Party	REQUIRED	Asset	Purpose
Provider	Yes	"Digital Twin Registry"	Allows a consumer to query for Part Type Twins and their Delivery Information submodels.
Provider	Yes	"Submodel Delivery Information"	Allows a consumer to read actual Delivery Information data related to a Part Type Twin.
Consumer	Yes	"Digital Twin Registry"	Allows a consumer to query for Part Type Twins and their Delivery Information submodels.
Consumer	Yes	"Submodel Delivery Information"	Allows a consumer to read actual Delivery Information data related to a Part Type Twin.

Table 4: Connector data assets

In the sections below the asset definitions of the two different kinds of assets are defined.

Connector Data Asset Structure for "Digital Twin Registry"

To allow partners to find the "Delivery Information" data for a specific Industry Core Part Type Twin, the provider MUST register a connector data asset (see details in [CX-0018]) specifying the address of the Digital Twin Registry of the provider (see [CX-0002]).

The data asset MUST be configured with the set of properties as defined in the table below.

Object	Property	Purpose	Usage & Constraints
	@id	Identifier of the asset	The asset ID MUST be unique and therefore MUST NOT be reused elsewhere.
properties	http://purl.org/dc/terms/type	Defines the "Digital Twin Registry" according to the Catena-X taxonomy.	MUST be set to {"@id": "https://w3id.org/catenax/taxonomy#DigitalTwinRegistry"} to allow filtering the data assets catalog for the respective "Digital Twin Registry".
properties	https://w3id.org/catenax/ontology/common#version	The version of the standard defining the implemented API of the "Digital Twin Registry"	MUST correspond to the version of the standard defining the Interfaces of the "Digital Twin Registry".

Table 5: Connector data assets request properties

Additionally security identification information MAY be added to secure the "Decentralized Digital Twin Registry".

When searching the Catalog of a provider, a consumer SHOULD use the following properties AND their values to identify the Data Asset specifying "Digital Twin Registry". In the connector Data Asset descriptions the API version valid for this standard is mentioned for the property https://w3id.org/catenax/ontology/common#version. The requester of a Data Asset MUST be able to handle multiple Data Asset for this endpoint, being differentiated only by the version. The requester SHOULD choose the Data Asset set with the highest compatible version number implemented by themselves. If the requester cannot find a compatible version with their own, the requester MUST terminate the data transfer.

Connector Data Asset Structure for "Submodel"

To allow partners to receive the actual "Delivery Information" data as defined in Chapter 3, the provider MUST register a connector data asset (see details in[ CX-0018]) specifying the address of the submodel endpoint (see [CX-0002]) providing the actual data.

The data asset MUST be configured with the set of properties as defined in the table below.

Object	Property	Purpose	Usage & Constraints
	@id	Identifier of the asset	The asset ID MUST be unique and therefore MUST NOT be reused elsewhere.
properties	http://purl.org/dc/terms/type	Defines the "Submodel API" according to the Catena-X taxonomy.	MUST be set to {"@id": "https://w3id.org/catenax/taxonomy#Submodel"} to allow filtering the data assets catalog for the respective "Submodel API".
properties	https://admin-shell.io/aas/3/0/HasSemantics/semanticId	The semantic identifier of the "Delivery Information" SAMM.	MUST be set to {"@id": "urn:samm:io.catenax.delivery_information:2.0.0#DeliveryInformation"} to externally define how the Submodel must be interpreted. MUST NOT be set, if different submodels may be returned by this API.
properties	https://w3id.org/catenax/ontology/common# version	Version of the Submodel Interface Specification	MUST be set to "3.0" in accordance to the Digital Twin in Catena-X Standards ([CX-0002]).

dataAddress	proxyMethod	Defines whether the endpoint allows to proxy the HTTPS method	SHOULD be set to "false" to only allow the API endpoint to receive GET requests.
dataAddress	proxyPath	Defines whether the endpoint allows to proxy paths for the URL	MUST be set to "true" to allow the API endpoint to receive appended paths of the HTTPS request. Setting this parameter depends on the implementation of the submodel lookup.
dataAddress	type	Defines the type of data plane extension handling the data exchange	MUST be set to "HttpData" to provide an API via an HTTPS proxy endpoint.

Table 7: Connector data assets request properties

Additionally security identification information MAY be added to secure the "Submodel API".

When searching the data assets catalog of a provider, a consumer SHOULD use the assetId previously determined via subprotocolBody of the SubmodelDescriptor's endpoint definition of subprotocol type "DSP". Refer to Chapter 4.1.2 for the definition of the subprotocolBody.

Property	Value
https://w3id.org/edc/v0.0.1/ns/id	{{CONNECTOR_ASSET_ID}} specified in the DSP endpoint of the SubmodelDescriptor (see Chapter 4.1.2)

4.1.2 INDUSTRY CORE PART TYPE TWIN REGISTRATION AND DEFINITION

4.1.2.1 SHELL DESCRIPTOR REGISTRATION

To allow partners to receive the actual "Delivery Information" data as defined in Chapter 3, the provider MUST register a Shell Descriptor in the dDTR (see [CX-0002]) so that a partner:

• May lookup the Industry Core Part Type Twin based on known identification data.
• May identify the connector endpoint providing access to the actual "Delivery Information" submodel data.

The Shell Descriptors represent each an Industry Core Part Type Twin and MUST follow the rules as defined in Chapter 2.1.4.

The Shell Descriptor MUST be configured with the set of properties as defined in the table below.

Object in ShellDescriptor	Property	Purpose	Usage & Constraints
	id	Defines the technical ID of the Asset Administration Shell representing a partner's twin.	MUST be unique following Industry Core Part Type standard [CX-0126] and is a technical Id randomly assigned as multiple Part Type Twins may be created for one Part Type. E.g. this number differs for the twins created at supplier and customer side.
	globalAssetId	Defines the Catena-X ID of the twin.	MUST be aligned with the partner's material. When referring to the same Part Type Twin, the same number MUST be used (see [CX-0126]).
	specificAssetIds	Identifiers that may be used to lookup Part Type Twins.	MUST be set according to the Industry Core Part Type standard [CX-0126]. See Table 10 for respective specific asset IDs. The "customerPartId" MUST be set by Customers and SHOULD be set by Suppliers.
submodelDescriptor	id	Technical identifier of a SubmodelDescriptor.	MUST be set to a unique identifier.
submodelDescriptor	semanticId	The semantic identifier of the "Delivery Information" SAMM.	MUST be set to { "type": "ExternalReference", "keys": [{ "type": "GlobalReference", "value": "urn:samm:io.catenax.delivery_information:2.0.0#DeliveryInformation" }] } to externally define how the Submodel must be interpreted.
submodelDescriptor > endpoint	interface	Defines the Submodel Interface (see [CX-0002]) and the version.	MUST be set to "SUBMODEL-3.0" to rely on current specification.
submodelDescriptor > endpoint > protocolInformation	href	Defines the direct link to the public API of the connector's data plane with a path that SHOULD be appended by the proxy, if needed.	MUST be set to the public API of the data plane providing the data with the path appended to directly access the submodel.
submodelDescriptor > endpoint > protocolInformation	subprotocol	Defines the usage of the connector based on DSP to access and use the submodel.	MUST be set to "DSP" to define the connector endpoint of the subprotocol.
submodelDescriptor > endpoint > protocolInformation	subprotocolBody	Defines the asset id in the connector and the connector address to access and use the submodel.	MUST be set to "id={{CONNECTOR_ASSET_ID}};dspEndpoint={{SUPPLIER_CONNECTOR_DSP_ENDPOINT}}" to provide the necessary information for contracting the submodel endpoint. Refer to Chapter 4.1.2 for the definition of the asset of the subprotocolBody.

Table 9: Properties relevant for the Shell Descriptor definition

When searching the submodel in the dDTR of a provider, a consumer SHOULD use the specific asset IDs as defined in [CX-0126]. Table 10 gives an overview of the specific asset IDs that the data provider added to the ShellDescriptor so that the data consumer may find the Industry Core Part Type Twin.

Specific Asset Id	Value
digitalTwinType	"PartType". Set to identify twins compliant to the Industry Core Part Type (see [CX-0126]).
manufacturerId	Supplier / Manufacturer partner BPNL (see [CX-0010])
manufacturerPartId	Supplier / Manufacturer partner identification number of the part.
customerPartId	Customer partner identification number of the part.

Table 10: Specific asset IDs of Industry Core Part Type Twins proposed to be used to lookup a twin in the dDTR

The Shell Descriptor defines the metadata of the Industry Core Part Type Twin. The following example Shell Descriptor represents a supplier's Shell Descriptor of a supplier who provides two customers access to an "Delivery Information" submodel. For further information on the creation of Part Type Twins, refer to Chapter 2.1.4.

Following [CX-0002], when searching the data assets catalog of a provider, a consumer SHOULD use the assetId determined via subprotocolBody of the SubmodelDescriptor's endpoint definition of subprotocol type "DSP" of the Submodel Descriptor of interest.

4.1.2.2 LOOKING UP A PART TYPE TWIN IN THE DDTR

To query the dDTR of a data provider, after contracting the usage via the data provider's connector (see [CX-0018]), the lookup API (see [CX-0002]) can be used relying on the specific asset IDs defined by the Industry Core Part Type (see [CX-0126]) that can be seen in Table 10 (table of shellDescriptorRegistration with specific asset IDs).

An example call relying on all information is given in the code sample below.

Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

GET: {{PARTNER_CONNECTOR_DATA_PLANE}}/lookup/shells?assetIds={"name":"digitalTwinType", "value": "PartType"},{"name":"manufacturerPartId", "value": "{{MATERIAL_NUMBER_SUPPLIER}}"},{"name":"manufacturerId", "value": "{{SUPPLIER_BPNL}}"},{"name":"customerPartId", "value": "{{MATERIAL_NUMBER_CUSTOMER}}"}

As a result identifiers of the ShellDescriptors will be returned. With this data, a data provider can read the ShellDescriptor to extract the endpoint data of the data provider. An example is given in the code sample below.

Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

GET: {{PARTNER_CONNECTOR_DATA_PLANE}}/shell-descriptors/{{AAS_IDENTIFIER}}

4.1.2.3 FETCHING SUBMODEL DATA

To fetch the Delivery Information Submodel data at the submodel endpoint of a data provider, after contracting the usage via the data provider's connector (see [CX-0018]), the submodel API (see [CX-0002]) can be used.

An example call relying on all information may be seen in the code sample below.

Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

GET: {{HREF_PATH}}/$value

5 PROCESSES

This section is normative

5.1 DELIVERY INFORMATION PROCESS

The aim of the Catena-X standard is to enable as much transparency between business partners as possible, provided that the exchange complies with German or EU competition law. The user must be aware that competitively sensitive information from one supplier or customer MUST NOT be shared with others. This means that Delivery Information related to other customers or suppliers MUST NOT be disclosed under any circumstances. The exchange of information must always be direct and unidirectional.

The responsibility for the transport may vary depending on the contractual agreements. This responsibility is defined by the INCOTERM. These are official standards provided by the International Chamber of Commerce (ICC). At the time of writing this standard there are 11 different INCOTERMS.

Code	Short description	Definition	Place to be specified
EXW	EXWorks	The supplier makes the goods available at their premises, or at another named place. This term places the maximum obligation on the customer and minimum obligations on the supplier.	At the factory site or any other place
FCA	Free CArrier	The supplier delivers the goods, cleared for export, at a named place (possibly including the supplier's own premises). The goods can be delivered to a carrier nominated by the customer, or to another party nominated by the customer.	Location of the supplier or location of the carrier
FAS	Free Alongside Ship	The supplier delivers when the goods are placed alongside the customer's vessel at the named port of shipment. This means that the customer has to bear all costs and risks of loss of or damage to the goods from that moment.	Agreed loading port (suitable only for ship loading)
FOB	Free On Board	The supplier bears all costs and risks up to the point the goods are loaded on board the vessel. The supplier's responsibility does not end at that point unless the goods are "appropriated to the contract" that is, they are "clearly set aside or otherwise identified as the contract goods".	Agreed loading port (suitable only for ship loading)
CFR	Cost And FReight	The supplier pays for the carriage of the goods up to the named port of destination. Risk transfers to customer when the goods have been loaded on board the ship in the country of Export.	Agreed port of destination (suitable only for loading ships)
CIF	Cost Insurance Freight	The supplier is responsible for covering the cost, freight, and minimum insurance to transport goods to the named port of destination, with risk transferring to the customer once the goods are loaded onto the shipping vessel. The supplier handles export customs clearance, but the customer is responsible for import customs clearance, unloading, and any further transportation.	Agreed port of destination (suitable only for loading ships)
DAP	Delivered At Place	The supplier delivers when the goods are placed at the disposal of the customer on the arriving means of transport ready for unloading at the named place of destination. The risk passes from supplier to customer from the point of destination mentioned in the contract of delivery.	Agreed delivery and destination location (usually destination terminal or customer´s location)
DPU	Delivered at Place Unloaded	The supplier delivers the goods, unloaded, at the named place of destination. The supplier covers all the costs of transport (export fees, carriage, unloading from main carrier at destination port and destination port charges) and assumes all risk until arrival at the destination port or terminal.	Agreed delivery and destination location (usually destination terminal or customer's location)
CPT	Carriage Paid To	The supplier pays for the carriage of the goods up to the named place of destination. However, the goods are considered to be delivered when the goods have been handed over to the first or main carrier, so that the risk transfers to customer upon handing goods over to that carrier at the place of shipment in the country of Export.	Agreed destination (usually destination terminal or customer's location)
CIP	Carriage Insurance Paid	The supplier is responsible for transporting the goods to a named place and providing insurance for the goods during transit. The risk transfers to the customer once the goods are handed over to the first carrier, but the supplier must pay transport and insurance costs to the specified destination. This term is suitable for all modes of transport, including containerized and multimodal shipments	Agreed destination (usually destination terminal or customer's location)
DDP	Delivered Duty Paid	The supplier is responsible for delivering the goods to the named place in the country of the customer, and pays all costs in bringing the goods to the destination including import duties and taxes. The supplier is not responsible for unloading.	Agreed delivery and destination location (usually destination terminal or customer's location)

Table 11: International Trade Administration. Incoterms 2020 (https://www.trade.gov/know-your-incoterms)

The incoterms allow three possible scenarios regarding Delivery Information responsibility:

Scenario	Customer responsibility	Supplier responsibility
1	Entire delivery (e.g., INCOTERM EXW)	None
2	None	Entire delivery (e.g., INCOTERM DDP)
3	Partial delivery: arrival (e.g., INCOTERM FAS)	Partial delivery: departure (e.g.,INCOTERM FAS)

Table 12: Scenario overview transport responsibilities

More details on each scenario are provided in the following sections.

5.1.1 CUSTOMER IS RESPONSIBLE FOR THE WHOLE DELIVERY (E.G. INCOTERM EXW)

5.1.1.1 ACTORS AND ROLES

The following actors and roles occur in the described process.

Actors	Role	Description
Customer	The customer submits an order. They are responsible for organizing the transportation of these parts from the origin to its destination. The customer acts as data provider, because he is responsible for the transport.	The customer provides critical Delivery Information to the supplier, including estimated pick-up and arrival times, to ensure coordinated preparation and efficient handling of the ordered parts at both ends.
Supplier	The supplier manufactures parts and makes them available at their origin. The supplier acts as a data consumer, because the consumer is responsible for the transport.	The supplier provides necessary information to the customer, including details about the availability and readiness of the parts for pick-up, contributing to an effective coordination of the transportation process.

Table 13: Actors and roles scenario 1

5.1.1.2 PROCESS PRESENTATION

In this scenario, the customer is responsible for organizing the pick-up of items from the supplier's location (origin) and their transportation to the customer's location. For transparency, the supplier requests Delivery Information from the customer. The customer responds with both the departure times and quantities, ensuring the supplier knows when to have the items ready for pick up. Additionally, the customer informs the supplier of the items' estimated arrival times at the destination facility.

Delivery information	-1	Today	+1	+2	+3
Departure	100	500	300	200	500
Arrival	800	100	500	0	300

Table 14: Delivery Information example scenario 1

Since the semantic model applies to different scenarios, the mandatory nature of eventTypes cannot be fully addressed in the model. Data MUST be provided according to the following restrictions:

• The customer MUST provide the departure information and MUST provide arrival information to give a benefit back to the supplier.
• If there is no confirmed date and time, the supplier can use a default estimation for the arrival information (e.g. departure date + 3 days).

There MUST be a departure information because the supplier needs to know when the goods will be picked up.

There MUST be arrival information to give the supplier more transparency.

5.1.2 SUPPLIER IS RESPONSIBLE FOR THE WHOLE DELIVERY (E.G. INCOTERM DDP)

5.1.2.1 ACTORS AND ROLES

Actors	Role	Description
Customer	The customer submits an order. The customer acts as a data consumer, because the supplier is responsible for the transport.	The customer submits an order at the supplier (quantity, location, preferred date).
Supplier	The supplier manufactures parts and makes them available. They are responsible for organizing the transportation of these parts from the origin to the destination. The supplier acts as data provider, because he is responsible for the transport.	The supplier coordinates all aspects of the delivery process, including selecting transportation methods, scheduling shipments, and providing the customer with regular updates on the delivery status and estimated arrival times.

Table 15: Actors and roles scenario 2

5.1.2.2 PROCESS REPRESENTATION

In this case, the supplier takes on the responsibility of organizing the entire delivery process from their facilities (origin) to the customer's destination. This includes arranging for the transportation of the items and ensuring they reach the customer's facility. The supplier must also maintain transparency throughout the process. They inform the customer of the departure times and quantities, ensuring the customer is aware of when to expect the delivery. Furthermore, the supplier provides updates on the delivery progress, including the estimated arrival times at the customer's facility, thus keeping the customer informed at every stage of the delivery process.

Transport information is only provided to the supplier.

Delivery information	-1	Today	+1	+2	+3
Departure	200	400	300	200	500
Arrival	600	300	500	10	300

Table 16: Delivery Information example scenario 2

As the semantic model applies to different scenarios, the mandatoryness of eventTypes can not be fully handled in the model. Data MUST be provided according to the following restrictions:

• The supplier MUST provide the estimated arrival information and MUST provide the departure information.
• If there is no confirmed date and time, the supplier can use a default estimation for the arrival information (e.g. departure date + 3 days).

There MUST be an arrival information because the customer needs to know when the goods will be available in the customer's factory. There MUST be departure information, to give the customer more transparency.

5.1.3 RESPONSIBILITY FOR THE DELIVERY IS SPLIT BETWEEN SUPPLIER AND CUSTOMER (E.G. INCOTERM FAS)

5.1.3.1 ACTORS AND ROLES

Actors	Role	Description
Customer	The customer submits an order. The customer is responsible for one half of the delivery. The customer acts as a data provider, because he is responsible for one half of the transport, and as a data consumer, because the supplier is responsible for the other half of the transport.	The customer coordinates and manages one part of the delivery process, which includes arranging transportation for the latter half of the journey, ensuring the parts are received from the midpoint, and providing necessary information to the supplier.
Supplier	The supplier manufactures parts and makes them available. The supplier is responsible for one half of the delivery. The supplier acts as a data provider, because he is responsible for one half of the transport, and as a data consumer, because the customer is responsible for the other half of the transport.	The supplier handles the initial part of the delivery process, including transporting the parts to a designated midpoint.

Table 17: Actors and roles scenario 3

5.1.3.2 PROCESS PRESENTATION

In this case the supplier is responsible for only one part of the transport (e.g. from departure from its factory (origin) until a middle point) and the customer takes over the responsibility for the rest of the transport (e.g. from middle point to its factory (destination)). In this case both customer and supplier can request Delivery Information of the other party.

Example:

Supplier A is in charge of the initial part of the transport, handling the pick-up and delivery of items from its location to a designated middle point. Customer A takes over the transport from the middle point, needs specific details about this first leg of the journey. Therefore, Customer A requests critical Delivery Information from Supplier A, such as departure time, pick-up location, and the quantity of items.

Delivery information	-1	Today	+1	+2	+3
Departure	100	500	300	200	500

Table 18: Delivery Information example scenario 3

Customer A assumes responsibility for the transport of goods from a predetermined middle point to its destination. Therefore, to gain transparency, Supplier A requests Delivery Information from Customer A, such as the estimated arrival times, final destination (e.g. Customer A's factory), and the quantity of goods to be shipped.

Delivery information	-1	Today	+1	+2	+3
Arrival	800	100	500	0	300

Table 19: Delivery Information example scenario 4

As the semantic model applies to different scenarios, the mandatoryness of eventTypes can not be fully handled in the model. Data MUST be provided according to the following restrictions:

• The supplier MUST provide the departure information.
• The client MUST provide the arrival information.

There MUST be departure information, to give the customer more transparency.

There MUST be arrival information, to give the supplier more transparency.
