CX-0142 Shop Floor Information Service v1.0.1

ABSTRACT

A Modular Production is part of the value chain. On the one hand, it has to guarantee flexibility and availability, and on the other, it has to allow for product mixes with small lot sizes. The effects of disturbances and decisions in this network are not limited to a local area, but also have a major impact on other partners in the value chain network. It is therefore necessary to exchange values from the shop floor directly with other members of the network, such as customers or their representatives, like logisticians. This communication is realized with the Shop-Floor-Information-Service (SIS). This service provides different types of information that a factory can offer to its customers. It is not dedicated to a specific purpose, as customers may decide how to handle the information themselves.

The current version of the standard provides two different kinds of data: Production Forecasting, and Production Tracking data. To give an example of forecasting data, suppose a customer wants to know when production is expected to start. He can use the Shop-Floor-Information-Service in order to get the information either directly, via cyclic messages or via notifications when the calculated production dates change. As an example of production tracking, a customer can request certain production attributes collected during production, such as the torque of a particular process step. This data can then be used for both documentation and tracking.

In order to exchange the data the Shop-Floor-Information-Service defines the necessary data models, such as the GetProductionForecast data and the ProvideProductionForecast data model as well as GetProductionTracking data and ProvideProductionTracking data model. This data exchange mechanism between Modular Production and the data consumer is realized via the Shop-Floor-Information API.

1 INTRODUCTION

1.1 AUDIENCE & SCOPE

This standard is relevant for

• Business Application Providers: their role is to implement the Shop-Floor-Information-Service,
• Data Providers, mainly Modular Productions: they have to provide the data required for the Shop-Floor-Information-Service,
• Data Consumers, e.g. tier n-1 factories, end customers or logisticians: they have to be able to process the data provided by the Shop-Floor-Information-Service.

Stakeholders within Catena-X

• PURIS, DCM: capacity planning requires a forecast of the products to be delivered,
• OSim: the Forecast Data from the SIS can serve as input for a OSim-simulation,
• Traceability: The production tracking aspect allows recalling production data for a specific product, which can be an asset for traceability.

1.2 CONTEXT AND ARCHITECTURE FIT

Higher-level, external influencing factors from the supply chain, such as delays in the logistics chain for supplier parts or short-term order changes, may invalidate a production plan that has already been drawn up. Today, such short-term changes in the general conditions of the production process can often only be taken into consideration indirectly and made through manual corrections. The solution approaches in the Modular Production use case aim to increase the flexibility of production in order to better leverage the existing business potential. For this purpose, services, interface, and data model definitions based on industry standards are offered with the goal of increasing the flexibility and reliability of industrial production. The shop floor is connected to the Catena-X network using the Catena-X standardized connectors. Modular Production will offer a Shop-Floor-Information-Service that supplies information about the production status and planning as needed by other partners in the Catena-X network. The goal is to enable individual production (lot size 1) at the price of series production. In particular, this is to be achieved by automating the orchestration of production resources and planning of production processes as much as possible, thus significantly reducing effort and planning times. A growth in efficiency in the sense of the OEE is achieved by reconfiguring the production in the event of faults to continue operation as well as possible. The increased flexibility creates the space for new business models, such as the interposition of highly prioritized, lucrative orders. As a consequence not only the production is required to be flexible and has to react quickly to changes, it also requires communication of future factory output to the customers. As part of a supply chain the products produced by a Modular Production are part of a bigger product. For this reason, certain parameters are offered to customers by the Production Tracking aspect for the overall documentation of the production process.

Both partners - a customer and a Modular Production - MUST be members of the Catena X network in order to communicate with each other. By registering a Modular Production in advance with the Discovery Service, a customer can find it via a so-called Business Partner Number (BPN). With the help of SSI (Self Sovereign Identity) the correct identity is guaranteed.

1.2.1 Forecasting

The customer uses the GetProductionForecastData call in order to request a production forecast, as specified in section 4.1. The Modular Production generates the required information internally by internal services like a scheduler and answers accordingly by calling ProvideProductionForecastData as specified in section 4.2. For cyclic messages or notifications, the Customer must unsubscribe from the service when the service is no longer required as described in Section 4.3.

The GetProductionForecastData as well as the ProvideProductionForecastData is using an AAS serialized as a JSON string which is sent through a connector as defined in [CX-0018] (e.g. Tractus-X EDC) mechanism, namely:

• GetProductionForecastData uses "GetProductionForecast" data model and
• ProvideProductionForecastData uses "ProvideProductionForecast" data model.

The unsubscribe call has no corresponding data model, as it is a simple HTTP DELETE.

The JSON string is standardized in section 3.1-3.3. The standard only describes the sending and receiving of Shop-Floor-Information-data through a data connector. The object is created and handled by applications of the companies involved, but these applications are not part of the standard.

1.2.2 Production Tracking

The customer uses the GetProductionTrackingData call in order to request production tracking information, as specified in section 4.4. The Modular Production provides the data stored in internal databases and replies accordingly by calling ProvideProductionTrackingData as specified section 4.5.

The GetProductionTrackingData as well as the ProvideProductionTrackingData is using an AAS serialized as a JSON string which is sent through connector defined in [CX-0018] (e.g. Tractus-X EDC) mechanisms - namely:

• GetProductionTrackingData uses "GetProductionTracking" data model and
• ProvideProductionTrackingData uses "ProvideProductionTracking" data model.

The JSON string is standardized in section 3.4-3.5. The standard only describes the sending and receiving of Shop-Floor-Information-data through a data connector. The object is created and handled by applications of the companies involved, but these applications are not part of the standard.

1.3 CONFORMANCE AND PROOF OF CONFORMITY

1.3.1 For Production Forecasting

All participants and their solutions will need to proof, that they conform to Catena-X standards. To validate that the standards are applied correctly, Catena-X employs Conformity Assessment Bodies (CABs). Any actor using the Production Forecasting aspect of the Shop-Floor-Information-Service, MUST implement, and follow the following standards:

• The Shop-Floor-Information-Service Forecasting core business logic – in section 5
• The Shop-Floor-Information-Service Forecasting standardized API – described section 4
• The Shop-Floor-Information-Service Forecasting standardized Data Model – described in section 3

In order to prove conformity, the participant needs to provide to the conformity assessment body:

• An example GetProductionForecast-JSON as created by their solution,
• An example ProvideProductionForecast-JSON as created by their solution,
• A proof that their solution can process the example payload JSON as listed below.

In case an assessee wants to get certified WHEN requesting assessment THEN the assessee produces a letter affirming that they adhere to this standard and the letter is signed by person who has full power of attorney

Note that in a future revision of this standard it is planned to offer descriptions of test sets including test cases and test data for validating API implementations.

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.

1.4 EXAMPLES

Disturbances of the supply chain always have a major impact on the following links in the chain. It is therefore necessary to inform the customers resp. their logistician as soon as possible, as the real date of manufacturing might vary from the one negotiated in the contract. The Shop-Floor-Information-Service therefore gives an update about the scheduled production times to allow a better planning for both the tier n-1 customer as well as for the logistic in-between.

1.4.1 Production Forecast

The following sections are providing examples for the API call as well as for the data models corresponding to the Production Forecast aspects.

1.4.1.1 API

Production Forecast provides three API calls. Examples for each call are listed below.

1.4.1.1.1 Example for GetProductionForecastData

An example JSON string for GetProductionForecast is discussed in section 1.4.1.2. GetProductionForecastData is the request to receive Shop-Floor-Information. It contains the BPNS of the requesting partner, the customerID, which is the internal customerID in the Modular Production management tool and the orderID, for which forecast information is requested. In addition, the requester can select one of the three communication modes: synchronous (the answer will be given immediately), cyclic (the information will be given cyclic with a negotiated cycle, e.g., every day etc.) and notification (changed production date). Each mode requires some additional parameters.

The execution of the endpoint which is used as the base URL in the asset definition is done via a connector as defined in [CX-0018] (e.g. Tractus-X EDC). As the endpoint execution parameters are sent as path parameters, they are added to the endpoint call at the data plane of the Tractus-X EDC, which passes them on to the endpoint at the Modular Production.

The GetProductionForecastData MUST be sent from the requestor of Shop-Floor-Information to the Modular Production using an HTTP GET request.

An example HTTP request is provided below:

GET /get-production-forecast HTTP/1.1
Host: localhost: 3000
Content-Type: application/json
Content-Length: 918

{
  "request": {
    "orderId": "C95_SLM140_1_W1",
    "customerId": "BPNL7588787849VQ",
    "deviationOfSchedule": {
      "value": 12,
      "timeUnit": "unit:secondUnitOfTime"
    },
    "productionForecastForAll": false,
    "version": "2.0.0",
    "notificationInterval": {
      "value": 12,
      "timeUnit": "unit:secondUnitOfTime"
    },
    "communicationMode": "synchronous"
  },
  "header": {
    "senderBpn": "BPNL6666787765VQ",
    "relatedMessageId": "d9452f24-3bf3-4134-b3eb-68858f1b2362",
    "expectedResponseBy": "2023-06-19T21:24:00+07:00",
    "context": "urn:samm:io.catenax.shopfloor_information.get_production_forecast:2.0.0",
    "messageId": "3b4edc05-e214-47a1-b0c2-1d831cdd9ba9",
    "receiverBpn": "BPNL6666787765VQ",
    "sentDateTime": "2023-06-19T21:24:00+07:00",
    "version": "2.0.0"
  }
}

1.4.1.1.2 Example for ProvideProductionForecastData

An example JSON string for ProvideProductionForecast is discussed in section 1.4.1.2. ProvideProductionForecastData returns the current forecast results in synchronous mode. In the case of the cyclic, the notification and the unsubscribe mode, it contains an immediate confirmation with the corresponding information. In case of a cyclic or notification event the current forecasting information will be sent using the ProvideProductionForecastData mechanism. The endpoint, which is used as the base URL in the asset definition, is executed via a connector as defined in [CX-0018] (e.g. Tractus-X EDC). Since the endpoint execution parameters are sent as path parameters, they are added to the endpoint call at the data plane of the Tractus-X EDC , which forwards them to the endpoint at the producer.

The ProvideProductionForecastData MUST be sent from the Modular Production to the consumer of the Shop-Floor-Information using an HTTP POST request. An example HTTP request is provided below:

POST /provide-production-forecast HTTP/1.1
Host: localhost:3001
Content-Type: application/json
Content-Length: 962

{
  "productionForecastResponse" : {
    "listOfForecastItems" : [ {
      "returnCode" : "ok",
      "precisionOfForecast" : {
        "value" : 12,
        "timeUnit" : "unit:secondUnitOfTime"
      },
      "reasonsForDelay" : "supplyProblems",
      "positionId" : "C95_SLM140_1_W1",
      "productionStatus" : "itemReceived",
      "productionForecast" : "2023-06-19T21:24:00+07:00",
      "forecastDate" : "2023-06-19T21:24:00+07:00"
    } ],
    "version" : "2.0.0",
    "communicationMode" : "synchronous",
    "iterationNumber" : 6
  },
  "header" : {
    "senderBpn" : "BPNL7588787849VT",
    "relatedMessageId" : "d9452f24-3bf3-4134-b3eb-68858f1b2362",
    "expectedResponseBy" : "2023-06-19T21:24:00+07:00",
    "context" : "urn:samm:io.catenax.shopfloor_information.provide_production_forecast:2.0.0",
    "messageId" : "3b4edc05-e214-47a1-b0c2-1d831cdd9ba9",
    "receiverBpn" : "BPNL6666787765VQ",
    "sentDateTime" : "2023-06-19T21:24:00+07:00",
    "version" : "2.0.0"
  }
}

1.4.1.1.3 Example for Unsubscribe

Unsubscribe is used to opt out of receiving information in the case of a cyclic or notification request. The endpoint, which is used as the base URL in the asset definition, is executed via a connector as defined in [CX-0018] (e.g. Tractus-X EDC). Since the endpoint execution parameters are sent as path parameters, they are added to the endpoint call at the data plane of the Tractus-X EDC, which forwards them to the endpoint at the producer.
The Unsubscribe request MUST be sent from the consumer of Shop-Floor-Information to the Modular Production using an HTTP DELETE request.

http://\{internal-server\}/relatedMessageId/00000000-0000-0000-C000-000000000042

The final id value should be copied from the GetProductionForecast. An example HTTP request is seen below:

DELETE /relatedMessageId/00000000-0000-0000-C000-000000000042  HTTP/1.1
Host: {\{internal-server\}}

1.4.1.2 Data Models

      }
    ],
    "version": "2.0.0",
    "communicationMode": "synchronous",
    "iterationNumber": 42
  }
}

1.4.1.2.3 ShopfloorInformationTypes

In order to use common data in the different models, ShopfloorInformationTypes have also been defined, an example of which is shown below::

{
  "timeValue": {
    "value": 12,
    "timeUnit": "unit:secondUnitOfTime"
  },
  "communicationMode": "synchronous"
}

1.4.2 Production Tracking

In the following sections examples for the API calls and the data models for production tracking are given.

1.4.2.1 API

Production Tracking provides two API calls. Examples for each call are listed below.

1.4.2.1.1 GetProductionTrackingData

An example JSON string for the GetProductionForecastData can be found in section 1.4.2.2. GetProductionTracking is the request to obtain Shop-Floor-Information regarding the manufacturing steps of a product. The Model itself contains the Catena-X Header Aspect Model (https://github.com/eclipse-tractusx/sldt-semantic-models/tree/4d239fc5709f71f39c3cf13581b5bcf960905157/io.catenax.shared.message_header/2.0.0), so that the BPNS of the requesting partner is provided. Within the request, the customerID, which is the internal customerID in the Modular Production management tool, and the identifierNumber, which is used to identify the product for which the production tracking data is requested, are required.

The execution of the endpoint which is used as the base URL in the asset definition is done via a connector as defined in [CX-0018] (e.g. Tractus-X EDC). As the endpoint execution parameters are sent as path parameters, they are added to the endpoint call at the data plane of the Tractus-X EDC, which passes them on to the Modular Production Tractus-X endpoint.

The GetProductionForecastTracking MUST be sent from the requester of Shop-Floor-Information to the Modular Production using an HTTP GET request.

An example of the HTTP request is listed below:

GET /get-production-tracking HTTP/1.1
Host: localhost:3000
Content-Type: application/json
Content-Length: 1007

{
  "request" : {
    "identifierNumber" : "box-12345678",
    "stepIdentifierList" : [ {
      "processStepId" : "Fuegen.Anpressen_Einpressen.Schrauben.Deckelverschrauben_01",
      "processParameterList" : [ {
        "processParameterSemanticId" : "0173-1#02-ABK233#001",
        "processParameterName" : "Drehmoment_Max"
      } ]
    } ],
    "customerId" : "550e8400-e29b-41d4-a716-446655440000",
    "identifierType" : "partInstanceId",
    "billOfProcessId" : "box-with-lid-12345678-bill-of-process",
    "version" : "1.0.0",
    "processReferenceType" : "processStep"
  },
  "header" : {
    "senderBpn" : "BPNL7588787849VQ",
    "relatedMessageId" : "d9452f24-3bf3-4134-b3eb-68858f1b2362",
    "expectedResponseBy" : "2023-06-19T21:24:00+07:00",
    "context" : "urn:samm:io.catenax.shopfloor_information.get_production_tracking:1.0.0",
    "messageId" : "3b4edc05-e214-47a1-b0c2-1d831cdd9ba9",
    "receiverBpn" : "BPNL6666787765VQ",
    "sentDateTime" : "2023-06-19T21:24:00+07:00",
    "version" : "2.0.0"
  }
}

1.4.2.1.2 ProvideProductionTrackingData

An example JSON string for the ProvideProductionTracking can be found in section 1.4.2.2. ProvideProductionTrackingData will return a set of manufacturing steps of a product, whereas each of these steps can feature one or multiple process parameters, that were specified with the GetProductionForecastData request. These process step information will be returned so that the requester will receive a single message, containing the ProvideProductionTracking information.

The execution of the endpoint which is used as the base URL in the asset definition is done via a connector as defined in [CX-0018] (e.g. Tractus-X EDC). As the endpoint execution parameters are sent as path parameters, they are added to the endpoint call at the data plane of the Tractus-X EDC , which passes them on to the producer's endpoint.

The ProvideProductionTrackingData MUST be sent from the Modular Production to the consumer of the Shop-Floor-Information using an HTTP POST request. An example HTTP request is provided below:

POST /provide-production-tracking HTTP/1.1
Host: localhost:3001
Content-Type: application/json
Content-Length: 1015

{
  "header": {
    "senderBpn": "BPNL7588787849VQ",
    "relatedMessageId": "d9452f24-3bf3-4134-b3eb-68858f1b2362",

    "sentDateTime": "2023-06-19T21:24:00+07:00",
    "version": "2.0.0"
  },
  "response": {
    "identifierNumber": "box-12345678",
    "catenaXId": "urn:uuid:580d3adf-1981-44a0-a214-13d6ceed9379",
    "identifierType": "partInstanceId",
    "version": "1.0.0",
    "processStepIdentifierList": [
      {
        "processStepId": "Fuegen.Anpressen_Einpressen.Schrauben.Deckelverschrauben_01",
        "processParameterValueList": [
          {
            "processParameterName": "Drehmoment_Max",
            "semanticId": "0173-1#02-ABK233#001",
            "processParameterQuality": "ok",
            "processParameterValue": "10"
          }
        ]
      }
    ]
  }
}

1.4.2.2 Data Models

This chapter provides examples of the production tracking data models, namely GetProductionTracking and ProvideProductionTracking, for common data in form of JSON for reference.

1.4.2.2.1 GetProductionTracking

The GetProductionTracking data model contains three different cases for a request, namely a partInstanceId, a billOfMaterialId and a billOfProcessId based request, which will be sent to the endpoint GetProductionTrackingData. The cases differ in the various optional fields that become mandatory for the individual cases. The following example illustrates the overall model, however, detailed examples for each of the aforementioned cases are provided in sections 1.4.2.2.1.1 through 1.4.2.2.1.3. In all cases, it is assumed that the required information is common knowledge to both the factory and the customer requesting GetProductionTracking.

{
  "request": {
    "identifierNumber": "box-12345678",
    "catenaXId": "urn:uuid:580d3adf-1981-44a0-a214-13d6ceed9379",
    "stepIdentifierList": [
      {
        "processStepId": "Fuegen.Anpressen_Einpressen.Schrauben.Deckelverschrauben_01",

4 APPLICATION PROGRAMMING INTERFACES

This section is normative

4.1 "GetProductionForecastData" API

This introduction holds for 4.1-4.3:

The GetProductionForecastData contains the request for forecast data sent by a Modular Production partner to a customer or a third party at the next lower level. All participants using the Shop-Floor-Information-Service in the role of a a customer or third party MUST be able to send GetProductionForecastData. All participants using the Shop-Floor-Information-Service in the role of a Modular Production MUST be able to receive and process GetProductionForecastData.

The following diagram shows the complete communication between the partners in an abstract way. It takes place in different phases:

1. Negotiation between the connector as in [CX-0018] (e.g. Tractus-X EDC),
2. Data connector of the partners using the needed policies,
3. GetProductionForecastData(...) - the call of the customer,
4. get the desired information via ProvideProductionForecastData(...) - transferred by Modular Production (synchronous, cyclic or notification-like),
5. Unsubscribe from the "GetProductionForecastData" service to stop receiving further information.

The two boxes in the middle represent the data connector like Tractus-X EDC of the partners. The communication between the respective connectors is transparent to the user (shaded). The transmission of the data for the request, as well as the response to the ProductionForecast is transmitted via the payload of the message. The immediate response (http response) does not contain any technical information. The left side represents the customer with his different requests. On the right is the Modular Production with a scheduler that generates the requested answers.

4.1.1 PRECONDITIONS AND DEPENDENCIES

The GetProductionForecastData API MUST be published towards the network using a Data Asset/Contract Offer in terms of the Dataspace Protocol as defined by IDSA, following the CX-0018 Eclipse Data Space Connector (EDC).

4.1.2 API SPECIFICATION

4.1.2.1 API Endpoints & resources

When sending a request to the GetProductionForecastDataEndpoint, the body MUST be composed out of two information objects: a header and content. Together they form the HTTP body that MUST be formatted as JSON.

    "notificationInterval": {
      "timeUnit": "day",
      "value": 2
    },
    "communicationMode": "synchronous"
  }
}

Available Data Types:

• The API GetProductionForecastData call MUST use the GetProductionForecast data model defined in section 3.1.
• The API MUST use JSON as the payload transported via HTTPS. More information on the data objects supported by the endpoints is provided in the corresponding sections of Section 3.1.
• Communication Mode MUST be one of the following items: synchronous, cyclic and notification.
• EnumTimeUnits MUST be one of the following items: unit:secondUnitOfTime, unit:minuteUnitOfTime, unit:hour, unit:day, unit:week, unit:month, unit:year.

4.1.2.2 DATA ASSET STRUCTURE

The HTTP GET endpoint introduced in chapter 4.1.1 MUST NOT be called from a partner directly. Rather, it MUST be called via the communication defined in [CX-0018]. Therefore, the endpoint MUST be offered as an Data Asset.

• The latter MUST have a property “asset.properties.asset:prop:id”. This property MUST be used to identify the asset when searching the assets catalog of a supplier as well as initiating a transfer process. Because the asset reflects the contractual relationship between Shop-Floor-Information-Service partners, only one asset with the aforementioned property MUST be visible to the customer at any time to avoid ambiguity. The value for this property can be chosen freely but must be unique.
• The asset definition SHOULD contain a property “asset.properties.asset:prop.description” for a human readable description of the asset when providing the contract offer catalog for the consumer and make it easier and readable for a human what kind of data this asset contains.
• The asset definition MUST contain a property “asset.properties.asset:prop:version” containing a version number to identify if there have been updates on an asset definition.
• The latter MUST have a property “dataAddress.properties.baseUrl” with a value containing the URL of the endpoint where the function “GetProductionForecastData” is implemented.
• Additionally, the dataAddress property MUST contain the parameter proxyPath with a value set to TRUE to enable the possibility to use connectors compliant to [CX-0018] as a reverse proxy by adding parameters to the URL.

The API version described in this standard document MUST be published in the property <https://w3id.org/catenax/ontology/common#version> as version 2.0 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 compatible version with their own, the requester MUST terminate the data transfer.

Each supplier MUST ensure that only their customers have access to the asset by using access and usage policies and respective contract definitions.

An example Tractus-X Data Asset definition with corresponding access / usage policies and a contract definition is shown below. Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

4.1.2.3 ERROR HANDLING

Every API endpoint defined in Chapter 4.1.2.11 MUST respond to incoming requests with HTTP status codes as described in [RFC9110]. The status codes for each endpoint are defined in the following sections.

Status Code	Description	Usage
200	OK	The request has succeeded.
201	OK, Precision not possible	The request has succeeded. Precision is not possible, the default precision will be used
400	Bad request	The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
401	Unauthorized	Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response.
403	Forbidden	The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource.
420	Unknown BPNS	The BPNS which is given as parameter is not registered in the data provider database as a direct partner.
421	Invalid CustomerId	The customerID unknown or invalid
422	Invalid OrderId	The orderID not found or invalid
423	Invalid Notification Interval	The data field Notification interval is not set with a proper value or missing
424	Invalid Deviation	The data field Deviation is not set with a proper value or missing
425	Forbidden	The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource.
426	incomplete Request

4.2.2.2 DATA ASSET STRUCTURE

The HTTP POST endpoint introduced in chapter 4.2.1 MUST NOT be called from a partner directly. Rather, it MUST be called via a data connection compliant to [CX-0018] communication. Therefore, the endpoint MUST be offered as an Data Asset.

• The latter MUST have a property “asset.properties.asset:prop:id”. This property MUST be used to identify the asset when searching the assets catalog of a supplier as well as initiating a transfer process. Because the asset reflects the contractual relationship between Shop-Floor-Information-Service partners, only one asset with the aforementioned property MUST be visible to the customer at any time to avoid ambiguity. The value for this property can be chosen freely but must be unique.
• The asset definition SHOULD contain a property “asset.properties.asset:prop.description” for a human readable description of the asset when providing the contract offer catalog for the consumer and make it easier and readable for a human what kind of data this asset contains.
• The asset definition MUST contain a property “asset.properties.asset:prop:version” containing a version number to identify if there have been updates on an asset definition.
• The latter MUST have a property “dataAddress.properties.baseUrl” with a value containing the URL of the endpoint where the function “ProvideProductionForecast” is implemented.
• Additionally, the dataAddress property MUST contain the parameter proxyPath with a value set to TRUE to enable the possibility to use a connector compliant with [CX-0018] as a reverse proxy by adding parameters to the URL.

An example Data Asset definition with a corresponding access / usage policy and contract definition are shown below. Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

4.3.2.3 ERROR HANDLING

Every API endpoint defined in Chapter 4.3.1 MUST respond to incoming requests with HTTP status codes as described in [RFC9110]. The status codes for each endpoint are defined in the following sections.

Status Code	Description	Usage
200	OK	The request has succeeded. Unsubscribe was successful
400	Bad Request	The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
401	Unauthorized	Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response.
403	Forbidden	The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource.
420	Unknown relatedMessageID	The combination of relatedMessageId and BPNS does not fit

4.4 "GetProductionTrackingData" API

This introduction holds for 4.4-4.5:

The GetProductionTrackingData contains the request for tracking data which is sent from a Modular Production partner to a customer or a third party on the next lower level. All participants using the Shop-Floor-Information-Service in the role of a a customer or third party MUST be able to send the GetProductionTrackingData . All participants using the Shop-Floor-Information-Service in the role of a Modular Production MUST be able to receive and process the GetProductionTrackingData .

The following diagram shows the complete communication between the partners in a abstract way. It takes place in different phases:

1. Negotiation between the data connectors of the partners like Tractus-X EDC using the needed policies.
2. GetProductionTrackingData(...) - the call of the customer.
3. get the desired information via ProvideProductionTrackingData(...) - transfered by Modular Production.

4.4.2.3 ERROR HANDLING

Every API endpoint defined in Chapter 4.4.1 MUST respond to incoming requests with HTTP status codes as described in [RFC9110]. The status codes for each endpoint are defined in the following sections.

Status Code	Description	Usage
200	OK	The request has succeeded.
400	Bad request	The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
401	Unauthorized	Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated". That is, the client must authenticate itself to get the requested response.
402	Unknown BPNS	The BPNS which is given as parameter is not registered in the data provider database as a direct partner.
403	CustomerId unknown	The customerID unknown
405	Forbidden	The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource.
421	uncomplete Request
422	identifierNumber unknown	The identifierID unknown
423	billOfMaterialId unknown	The billOfMaterialId unknown
424	billOfProcessId unknown	The billOfProcessId unknown
425	bomElementId unknown	The bomElementId unknown
426	capabilityId unknown	The capabilityId unknown
427	processStepId unknown	The processStepId unknown
428	other parameters unknown	Other parameters unknown

Available Data Types:

• The API MUST use JSON as the payload transported via HTTPS. More information on the data objects supported by the endpoints is provided in the corresponding sections of Section 4.4.1.
• The API ProvideProductionTrackingDatacall MUST use the ProvideProductionTrackingData data model as described in 4.4.1.
• processParameterQuality MUST be one of the following items: ok, inexact, noValue.

4.5.2.2 DATA ASSET STRUCTURE

The HTTP POST endpoint introduced in chapter 4.5.1 MUST NOT be called from a partner directly. Rather, it MUST be called via a connector compliant with [CX-0018] communication. Therefore, the endpoint MUST be offered as an Data Asset.

• The latter MUST have a property “asset.properties.asset:prop:id”. This property MUST be used to identify the asset when searching the assets catalog of a supplier as well as initiating a transfer process. Because the asset reflects the contractual relationship between Shop-Floor-Information-Service partners, only one asset with the aforementioned property MUST be visible to the customer at any time to avoid ambiguity. The value for this property can be chosen freely but must be unique.
• The asset definition SHOULD contain a property “asset.properties.asset:prop.description” for a human readable description of the asset when providing the contract offer catalog for the consumer and make it easier and readable for a human what kind of data this asset contains.
• The asset definition MUST contain a property “asset.properties.asset:prop:version” containing a version number to identify if there have been updates on an asset definition.
• The latter MUST have a property “dataAddress.properties.baseUrl” with a value containing the URL of the endpoint where the function “ProvideProductionForecast” is implemented.
• Additionally, the dataAddress property MUST contain the parameter proxyPath with a value set to TRUE to enable the possibility to use a connector compliant with [CX-0018] as a reverse proxy by adding parameters to the URL.

An example Data Asset definition with a corresponding access / usage policy and contract definition are shown below. Note: Expressions in double curly braces {{}} must be substituted with a corresponding value.

5.1 "Production Forecast" PROCESS

5.1.1 ACTORS AND ROLES

Any application provider that develops the Production Forecast Aspect of the Shop-Floor-Information-Service has to grant fulfilllment of these requirements.

• The solution MUST be designed to consider requirements for a trusted usage environment (e.g., identity verification and /or verification process).
• The solution MUST be designed to require a contractual agreement in compliance with antitrust requirements in the usage environment (e.g., data contracts as a prerequisite for carrying out a data exchange). For reference see CX-0001 guidelines.
• The solution MUST be designed to limit visibility and/or access to concrete data content as much as possible (e.g., data offer does not yet allow data access).
• The solution MUST be designed to require the implementation of notice and/or acknowledgement concepts to raise awareness of antitrust issues during use (e.g., helpdesk or pop-up info).
• The solution MUST be designed to ensure traceability/reconstructability of processes through appropriate documentation and at the same time data sovereignty over concrete data content (e.g., through access, deletion or destination rights).
