CX-0115 Manufacturing Capability Exchange 1.0.1

ABSTRACT

Manufacturing-as-a-Service (MaaS) scenarios focus on connecting buyers looking for manufacturers in possession of the available production know-how and resources to produce specific products.

Sharing information about the required and available manufacturing capabilities in an interoperable manner is fundamental for any MaaS solution providing basic and value-added services such as automated search and matchmaking.

A common description of the manufacturing capabilities based on a standardized semantic definition is therefore key for facilitating such an information exchange between Catena-X participants.

FOR WHOM IS THE STANDARD DESIGNED

COMPARISON WITH THE PREVIOUS VERSION OF THE STANDARD

This is the first version of the CX-0115 standard. The CX-0115 standard obsoletes the following Catena-X standards:

CX-0052 ManufacturingCapability Aspect Model v1.0.0

1 INTRODUCTION

1.1 AUDIENCE & SCOPE

This section is non-normative

This standard is relevant for the following roles defined in [CX-OMW]:

Business Application Provider providing Manufacturing-as-a-Service solutions
Data Provider willing to provide information about required or available capabilities
Data Consumer interested in requesting information about required or available capabilities
On-Boarding Service Provider supporting the onboarding of participants with their business and capability information
Enablement Service Provider that support the workflow regarding the derivation and refinement of participants capabilities

The scope of this standard is only the “ManufacturingCapability” aspect model and the provisioning of manufacturing capabilities data in accordance with [CX-0002].

1.2 CONTEXT AND ARCHITECTURE FIT

This section is non-normative

Buyers occasionally need to search for manufacturers or specific manufacturing process steps. The reasons for that might be that production at their own premises is currently not possible due to resource or capacity bottlenecks (e.g. material shortage, machine defect, no machine with required capabilities available, etc.), that other suppliers are currently not able to deliver a particular product, or that a prototype of a new product is needed before a production and investment decision is made. Instead of searching for the right supplier based on already existing but possibly limited contacts, Catena-X MaaS enables the distribution of a pre-configured manufacturing request across a network of ODM platforms and supplier networks in a domain-independent and IP-secure manner.

Buyers looking for manufacturers to purchase specific products or manufacturing process steps from, must provide specific information on how the products should be manufactured. This includes the required manufacturing capabilities that a manufacturer needs to possess in order to manufacture the desired product or perform the manufacturing process steps. Manufacturers, on the other hand, are interested in providing information about their know-how and available capabilities, making them discoverable for potential buyers and allowing them to acquire new customers, orders and projects.

The standardized "ManufacturingCapability" model defined in this document is a first step towards a common interoperability of manufacturing capabilities by all participants in a Manufacturing-as-a-Service scenario. It therefore fosters the interoperability of suppliers and buyers in the manufacturing industry, enabling faster alignment with less effort and making collaboration less error-prone.

Figure 1 shows the high-level architecture of the manufacturing capability 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 manufacturing capability 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. 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.

3 ASPECT MODELS

This section is normative

3.1 ASPECT MODEL "Manufacturing Capability"

3.1.1 INTRODUCTION

This section describes the "Manufacturing Capability" semantic model used in the Catena-X network. 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.manufacturing_capability:3.1.0

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.

https://github.com/eclipse-tractusx/sldt-semantic-models/blob/main/io.catenax.manufacturing_capability/3.1.0/ManufacturingCapability.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 MUST 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 MUST 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 "Manufacturing Capability" API

The Manufacturing Capability API defined in this section enables the exchange of the Manufacturing Capability data between Catena-X manufacturers and the Manufacturing Network Registry (MNR) in an interoperable manner. The manufacturer maintains a set of Submodels (one for each plant) and registers them in their Digital Twin Registry in accordance with [CX-0002]. To exchange the manufacturer's manufacturing capabilities, the manufacturer must first onboard in Catena-X MaaS. Details on the manufacturer onboarding process can be found in the Runtime View section of the [MaaS KIT]. It is assumed that the Asset ID is known in Catena-X. Figure 2 shows a high level overview of the intended data exchange flow.

Figure 2: Manufacturing Capability data exchange flow

The API relies on asynchronous communication between the involved parties.

A data exchange is initiated by the data consumer (Manufacturing Network Registry) sending a Pull request to the data provider (Manufacturer) to get the Manufacturing Capabilities.
Upon receiving a valid request, the manufacturer sends back the Manufacturing Capability Submodel so that the Manufacturing Network Registry is able to process with the capabilities of the Manufacturing Capability Submodel.

4.1.1 PRECONDITIONS AND DEPENDENCIES

To participate in the Catena-X dataspace, both the data consumer and the data provider MUST be registered and onboarded as defined in [CX-006].

A dataspace connector conformant to [CX-0018] MUST be used to make the Manufacturing Capability API available to network participants.

The API endpoint defined in Chapter 4.1.2.1 MUST therefore be offered as data asset / contract offer as defined in [CX-0018].

4.1.2 API SPECIFICATION

4.1.2.1 API Endpoints & Resources

To support the exchange of Manufacturing Capability data, the Manufacturing Network Registry acting as a data consumer MUST define a single endpoint supporting the HTTP GET request method as described in [RFC9110]. The structure of the endpoint MAY be freely chosen. The address of the endpoint MUST be provided as part of the data asset structure defined in Chapter 4.1.3 of this document.

Exchanging Data via the Manufacturing Capability API requires manufacturers and the Manufacturing Network Registry to both act in the roles of data provider and data consumer. The API is a superset of [CX-0002] with the following specializations:

A manufacturer MUST host and expose a Submodel ManufacturingCapability via the Submodel-API as defined in [CX-0002].
Additionally, manufacturers and the Manufacturing Network Registry MUST offer the PatchSubmodel-Operation with the content-modifier $value on all Submodels as defined in [ AAS Pt.2].
A manufacturer MUST be capable to update the ManufacturingCapability-Submodel hosted by the Manufacturing Network Registry.

4.1.2.2 Available Data Types

The API MUST use JSON as the payload transported via HTTPS.

4.1.3 CONNECTOR DATA ASSET STRUCTURE

Obligations for the data space connector Asset Definition of the Digital Twin Registry are inherited from [CX-0002].

Obligations for the data space connector asset definition of a Submodel are inherited from [CX-0002].

Of the example below, only the properties- section is defined as normative. The example only signifies a single registered Submodel. While bundling several Submodels into a single data space connector asset, there are no normative requirements for data space connector asset properties.

{
  "@context": {
    "ctx": "https://w3id.org/catenax/taxonomy#",
    "cx-common": "https://w3id.org/catenax/ontology/common#",
    "aas-semantics": "https://admin-shell.io/aas/3/0/HasSemantics/"
  },
  "@id": "{{ID for the data space connector asset}}",
  "properties": {
    "dct:type": {
      "@id": "ctx:Submodel"
    },
    "cx-common:version": "3.0",
    "aas-semantics:semanticId": "{{urn:samm:io.catenax.manufacturing_capability:3.1.0}}"
  },
  "dataAddress": {
    "@type": "DataAddress",
    "type": "HttpData",
    "proxyPath": "true",
    "proxyBody": "true",
    "proxyMethod": "true",
    "proxyQueryParams": "true",
    "baseUrl": "{{Submodel endpoint ending before /submodel}}"
  }
}

The API version described in this standard document MUST be published in the in the property https://w3id.org/catenax/ontology/common#version as version 1.0 in the asset. The requester of an asset MUST be able to handle multiple assets for this endpoint, being differentiated only by the version. The requester SHOULD choose the asset with the highest compatible version number implemented by themselves. If the requester cannot find a version compatible with their own, the requester MUST terminate the data transfer.

Connector Policy Definition

The following policy is an example to let a single business partner pass. As described in standard CX-0152, this policy constraint can only be used as part of an accessPolicy.

{
  "@context": [
    "http://www.w3.or/ns/odrl.jsonld",
    "https://w3id.org/catenax/2025/9/policy/context.jsonld"
  ],
  "@type": "Set",
  "@id": "{{POLICY-DEFINITION-ID}}",
  "policy": {
    "permission": [
      {
        "action": "access",
        "constraint": [
          {
            "and": [
            "leftOperand": "BusinessPartnerNumber",
            "operator": "isAnyOf",
            "rightOperand": "{{hard-coded BPNl of privileged consumer}}"
            ]
          }
        ]
      }
    ]
  }
}

Connector Contract Definition

The following example for a data space connector contract definition connects the defined policy to the defined asset.

{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/"
  },

}

4.1.4 ERROR HANDLING

Error handling is specified by [CX-0002] and [AAS Pt.2].

4.1.5 DTR REGISTRATION

As mandated by [CX-0002], all Data-Providers must provide a Digital Twin Registry (DTR) and use it to link their Submodels to identified assets. Assets in the DTR are identified via specificAssetIds.

When registering Submodels with semanticId ManufacturingCapability, the data provider (Manufacturer) MUST create a single specificAssetId with key creationEntityId and value a UUIDv4 as value.

All other attributes are standardized in [CX-0002] or [AAS Pt.2] respectively.

Example:

{
  "id": "{{id of the AAS}}",
  "idShort": "{{short name of the AAS}}",
  "specificAssetIds": [
    {
      "name": "creationEntityId",
      "value": "{{someUuidV4}}",
      "externalSubjectId": {
        "type": "ExternalReference",
        "keys": [
          {
            "type": "GlobalReference",
            "value": "*"
          }
        ]
      }
    }
  ],
  "submodelDescriptors": [
    {
      "id": "{{someSubmodelId}}",
      "semanticId": {
        "type": "ExternalReference",
        "keys": [
          {
            "type": "GlobalReference",
            "value": "urn:samm:io.catenax.manufacturing_capability:3.1.0"
          }
        ]
      },
      "endpoints": [
        {
          "interface": "SUBMODEL-3.0",
          "protocolInformation": {
            "href": "{{dataplane baseurl extended with the appropriate path ending on /submodel}}",
            "endpointProtocol": "HTTP",
            "endpointProtocolVersion": [
              "1.1"
            ],
            "subprotocol": "DSP",
            "subprotocolBody": "id={{ID of the data space connector asset the submodel is living behind}};dspEndpoint={{controlPlaneEndpoint}}",
            "subprotocolBodyEncoding": "plain",
            "securityAttributes": [
              {
                "type": "NONE",
                "key": "NONE",
                "value": "NONE"
              }
            ]
          }
        }
      ]
    }
  ]
}

4.1.6 DATA EXCHANGE

Restrictions on the exchanged data can be retrieved from the data models. Additionally, the following definitions apply.

The ManufacturingCapability Submodel data MUST be sent from the manufacturer to the Manufacturing Network Registry using an HTTP GET response. The data format described here MUST be followed for the exchange of the capabilities needed for manufacturing.

Multiple ManufacturingCapability aspects MAY be sent in one transfer as a JSON list. If only one ManufacturingCapability aspect is transmitted, it MUST still be sent as a list with one entry.

The serialized JSON MUST NOT be larger than 15 MiB in size.

The ManufacturingCapability endpoint MUST be implemented by all participants who wish to participate in Catena-X MaaS as a manufacturer. Manufacturers MUST be able to response with their manufacturing capabilities to the Manufacturing Network Registry HTTP GET request.

The data payload itself MUST be a valid JSON string.

All attributes marked as mandatory in ManufacturingCapability aspect model MUST be included in the dataset. Attribute marked as 'Optional' can be included in the data set.

The usage of the attributes in the data model MUST follow the attribute descriptions in the definitions of the ManufacturingCapability aspect model.

When exchanging data, the usage of UUIDv4 is required in order to reduce the probability of collision as well as to eliminate certain attack vectors. The UUIDv4 MUST be generated according to [RFC4122].
