6 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 6 of 28 1 General 1.1 Preface The introduction of digital technology throughout the lifecycle of an automobile has brought about fundamental changes in the handling of product data. These changes also affect the long-term archiving of digital product data in particular. Up until now, the long-term archiving (LTA) of product data involved the creation and storage of 2D drawings. Administrative and organizational product data (PDM/PLM data) was archived as part of the 2D drawing (e. g. in the title block) and/or in other documents. Without 2D drawings, the 3D CAD model shall now fulfill the same requirements for longterm archiving. The recommendation VDA 4958 was drawn up because there were previously no rules according to which 3D CAD data could be archived securely and later be accessed and interpreted. The fourth part of the recommendation addresses the following aspects: - Identification of assessment areas and test criteria for conformity testing involving an LTA solution for digital product data which is not based on technical drawings with respect to the recommendations in Parts 1 to 3 (see 1.5). - Description of special characteristics regarding the testing and certification of this LTA solution as an extension of the generally applicable criteria for proper documentation. ISO9001 provides a process-oriented approach for the definition of requirements relating to quality management systems. It can be used, for example, to verify the ability to ensure the permanent availability of products or satisfy the requirements of customers and/or government agencies. Based on the generally accepted principles of computer-based accounting systems (GoBS) and ISO9001, the IT association Verband Organisations- und Informationssysteme e.v. (VOI) and TÜViT have already developed test criteria for document management solutions (PK-DML) that allow for a proper certification procedure. These criteria create a basis for a neutral third party to verify trustworthy and audit-safe document management solutions. Part 4 of VDA 4958 provides recommendations for the verification of reliable LTA workflows as the basis for certification based on, and in addition to, IS09001 while giving due consideration to PK-DML. Certification of the LTA workflows serves as proof that, at the respective time, everything humanly possible was done according to the prevailing state of the art with regard to the proper and adequate archiving and corresponding documentation. The recommendations contained in Part 4 are to be viewed as an extension of the archiving and certification processes already established in 2D environments, i.e. previously valid certification criteria also apply to product data which is not based on technical drawings and which falls within the scope of application of VDA Annex A (Source: PK-DML) provides a comparison of VDA 4958 and ISO9001.
7 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 7 of Objectives and scope of application VDA 4958 is relevant to development and documentation processes if 3D representations (3D master models) are the only basis for development and documentation and if the established 2D archiving processes are not longer applicable due to economic or technical aspects. The description of the data and models relevant to long-term archiving refers to 3D CAD data and requisite non-geometric data. With regard to this data, every company shall give due consideration to generally accepted rules and recommendations regarding the archiving of digital documents such as, for example, security and backup solutions in the archive system. VDA provides recommendations for the verification of reliable LTA workflows as the basis for certification with the following technical background: Basic conditions shall be created that ensure that 3D CAD models and product data for drawing-based documentation can be put on par with each other from both a technical and legal point of view. This includes understanding and verification of the integrity (see VDA ). The characteristics of potential company-specific LTA solutions can be evaluated on the basis of generally accepted assessment aspects. The assessment relates to all aspects of an LTA solution such as, for example, organizational measures, man-machine interfaces, IT infrastructure as well as all securityrelated requirements within the overall context of the LTA process. Transparency shall be established for all aspects in order to ensure verifiability. 1.3 Changes compared with previous version Version Change Chapter Page 1.0 No changes; first edition 1.4 Compatibility with previous versions Not applicable; first edition. 1.5 Structure of the recommendation Part 1 identifies requirements relating to the long-term archiving of product data that exists in digital form only, summarizes certain legal and technical aspects and provides the basis for the other parts of the recommendation. Part 2 provides recommendations for designing the processes used to prepare the data for long-term archiving, the archiving of the data itself, and the steps required to access and reprocess the archived data. Part 3 defines the minimum requirements to be satisfied by the information in the 3D CAD representations and non-geometric product structure descriptions that is to be archived both from the user s point of view and on the basis of the process definition. Part 4 provides recommendations for the verification of reliable LTA workflows as the basis for certification. Chapter 2 describes the basic principles for assessing LTA solutions. Chapter 3 identifies the relevant assessment areas and the test criteria that shall be taken into consideration.

Technischer ÜberwachungsVerein InformationsTechnik GmbH is an accredited testing and certification service provider in the field of IT security Definition of terms According to PK-DML, a Document Management System (DMS) is an electronic system which provides features that safeguard the probative force of electronic documents throughout their lifecycle including versioning handling and processing control archiving output and reproduction protection functions (access authorization, integrity, authenticity, etc.) Document management systems are initially all-purpose solutions, i.e. they are not subject to any factual or legal restrictions regarding usage. Systems with these kinds of restrictions are solutions of special applications (e. g. financial accounting systems). This distinction is important for the operator because the factual and legal significance of all-purpose solutions arises from its individual usage. LTA solutions are comparable to DMS solutions. probative force is a term used to refer to features that are fully transparent and are protected against unintentional changes and manipulations in a defined manner. operator of an LTA solution is the legally responsible party. If operative application is outsourced to a third party (e. g. to a computer center), this does not change the legal operator. LTA solution is the holistic view of a technical and organizational overall solution. The view of an LTA system is therefore expanded in the assessment criteria to an LTA solution (LTA).

10 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 10 of 28 2 Basic principles of assessment The criteria described comprises the minimum requirements. Fulfilment of these requirements is a prerequisite for successful certification. In this sense, they are K.O. criteria. 2.1 Assessment aspects The test criteria in Chapter 3 result from giving due consideration to the following aspects: - correctness - completeness - transparency - immutability - availability To ensure a separation of testing responsibilities, a distinction is made between technical/organizational aspects and legal aspects. The legal aspects do, however, have an impact on the correct technical and organizational implementation. LTA solution Technical fields of application Manufact. documents 3D CAD data E/E documen - tation Objects subject to technical tests Tech. + organizational implementation Correctness Completeness Transparency Immutability Availability Core criteria Objects according to VDA Procedural documentation Figure 1: Assessment aspects Figure 1 shows the assessment aspects for an LTA solution for storing 3D CAD data. Specifications for other areas of application such as, for example, manufacturing documents or electric/electronic documentation could be made in the same way. 2.2 Overview of the assessment areas The procedural documentation that provides the basis for the examination shall give consideration to all the relevant aspects of the solution, thus making an assessment of the requirements possible. It shall therefore provide information on, at least the assessment areas listed below.
11 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 11 of 28 These assessment areas and the measures recommended for these areas are based on the PK-DML test criteria and are described in Chapter 3. (1) General description of the area of application (2) Factually logical system solution (3) Technical system solution and migration (4) IT security (5) Technical operation (6) Processes (7) Employee qualifications (8) Tests (9) Maintenance (10) Internal control system (ICS) The development of suitable procedural documentation is one of the main tasks involved in ensuring verifiability, and it is a prerequisite for possible certification. The procedural documentation provides a red thread and explains the implementation concepts as well as the main coherencies. The full particulars for company-specific implementation are explained in referenced secondary documents. This also makes it easier to maintain the documentation. The following provides brief guidelines for creating procedural documentation. To facilitate the study of the documents within the context of an examination, it is appropriate and necessary to adhere to the above-mentioned 10-point structure. To keep creation and maintenance as simple as possible, references to existing company-specific documentation and other related documentation in which, for example, organizational structures are maintained make sense and are permitted. In this case, however, it shall be ensured that prompt access to these documents is possible and that the overall context remains fully transparent with regard to content and chronology. Information and aspects that are subject to frequent change or updates should be separated from the main body of text as easily maintainable appendices or secondary documents. An appropriate reference in the appropriate chapter is then sufficient. Certification is always performed on the basis of ISO 9001 at a minimum. Certification according to the PK-DML test criteria and in consideration of the recommendations provided in VDA 4958 is recommended with regard to the specific needs relating to the LTA of 3D product data. 2.3 Benefits The structural organization and the holistic IT approach create transparency in complex LTA solutions. Transparency provides an opportunity to avoid risks and costs. The criteria described comprise the minimum requirements that shall be satisfied in order for an LTA solution to be certified. All the individual criteria have been formulated as positive statements. Certification can only be performed if all the statements apply to the LTA solution being examined or have been implemented accordingly. In this sense the statements are K.O. criteria.
12 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 12 of 28 3 Assessment criteria The following sections provide a description of the main assessment criteria that are to be examined. The assessment is performed using individual test criteria, which are listed separately for each assessment criterion and described briefly. The assessment criteria comprise both requirements relating to the operator of an LTA solution as well as the actual test criteria. 3.1 Assessment area 1: General description of the area of application The general description of the area of application provides an overview of the company, its structural and procedural organization, as well as the general conditions and integration of the LTA solution in the company Description of the organization The company and the organizational units involved in the archiving process shall be described in sufficient detail and their organization-specific focus shall be identified.

Additional information about a separation of roles will be provided in section Documents in the archive A list of the documents in the archive and their retention periods shall be maintained, and proof of compliance with the retention periods shall be provided. The retention periods follow the recommendations made in VDA and are documented using the LTA metadata (see data directory in VDA ).
14 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 14 of Processing rules The processing rules shall be described as company-specific operating and procedural instructions. They shall be in line with the LTA reference process. This not only includes instructions for the organizational units and employees but also technical rules for automated procedures in the LTA solution. In the procedural documentation relevant to certification, it is sufficient to name the main procedural instructions together with a brief description of what they regulate and who shall follow them Electronic signatures Electronic signatures shall used in accordance with the LTA reference process. A distinction shall be made between signed incoming documents (e. g. in the SIP Submission Information Package) and the time signature generated during archiving as proof of the integrity of a digital document Additional guidelines All the guidelines to be observed by the archiving process and the IT solutions involved such as laws, regulations, requirements and agreements shall be documented individually. The documentation shall be supplemented with VDA The responsibility and authority of the person assigned to the archiving environment shall be defined to ensure that requirements of VDA 4958 are met and that company-specific QM systems and guidelines continue to be supported. 3.3 Assessment area 3: Technical LTA solution and migration The technical implementation of the LTA solution and the audit-proof archiving it provides shall be described in an easily understood manner. The description shall include not only a general survey of the hardware and software used, but also a description of the individual components and their interaction. A concept for ensuring the long-term availability of the archived document shall also be included.

This also includes the logging of all sensitive operations and transactions that involve the archive according to VDA Threats and measures The protection requirements and specific threats to the components of the LTA solution shall be identified. The protection requirements relating to the individual components are determined by the extent to which they merit protection and an analysis of the threats. The measures needed to address these threats shall be described on the basis of organizational and technical solutions Disaster recovery planning Disaster recovery planning for the LTA solution shall be described. It ensures that the content information and administrative data, as well as all the AIPs stored in the archive, can be recovered in the event of a disaster or other breakdown LTA-specific data protection concept The specific data protection measures for the LTA solution shall be described. The description, including the appropriate and easily understood rationale behind the measures, shows how data loss can be reliably avoided User administration and authorization concept The various types of access and access rights shall be described according to the roles in the LTA process (see VDA ). Due to the security risks (3.4.1) and sensitivity of the LTA data, the differences with regard to the general IT user administration and authorization concept in particular shall be documented for the LTA solution. Measures for access protection can be implemented directly at operating system level or in the application level of the LTA solution Transaction and data consistency protection As part of the LTA system solution, especially with regard to the interfaces to third-party systems from which documents are received, the mechanisms and concepts for transaction and data consistency protection shall be documented Logging All procedures and transactions in the LTA solution that are relevant to logging are identified in VDA The requisite logging depth shall be specified and documented as required for each use case and the company in question. It shall be possible to present the logs at any time for the purpose of transparency and providing proof of the correctness of the procedures in the LTA environment System stability Measures to ensure the stability of LTA solution shall be documented, and the reasons for these measures shall be given.
18 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 18 of Access control LTA solutions require special measures for access control. These measures shall be described according to the role in question. Access control includes, for example, access to buildings, departments, individual rooms and the archive itself as well as access control relating to the entry, editing and reading of information (see also 3.4.4) Data privacy laws and control system Proof shall be provided that the requirements relating to control measures in accordance with current data protection regulations are fulfilled. In addition to data protection legislation, attention shall also be given to other regulations such as, for example, employee data protection based on the Works Constitution Act, depending on the usage involved. The requisite control measures arise from the data protection regulations and have normally already been taken into consideration by the general IT security concept or access protection. 3.5 Assessment area 5: Technical operation A description of the measures taken to ensure the proper operation of the LTA solution (operating conditions, operating requirements and operating processes) and their implementation shall be provided. The organizational structure of the organizational units responsible for operation and their interaction with regard to the implementation of the defined measures shall be described. The following sections examine the general constructional and organizational prerequisites for proper LTA operation. Technical operation is subdivided into general organizational conditions, operational processes during normal operation and operational processes in emergency scenarios. During standard operation, focus is placed on the handling of the LTA system components and the data storage media as well as on monitoring. In emergency scenarios, on the other hand, focus is placed on ensuring fast recovery of the system, the content information and the administrative data without any losses Responsibilities Responsibilities relating to operation of the LTA solution shall be regulated and documented accordingly. This documentation shall include, at a minimum, the responsibilities and a description of the roles. It is recommended that a distinction be made between internal and external persons and organizational units in the description of the roles involved and their respective responsibilities. A detailed description of the responsibilities supplements the information provided in the assessment area 1 (3.1) Building Related prerequisites Proof shall be provided that the site used for operating the LTA solution satisfies the contractual prerequisites, so that the requirements of other assessment areas (e. g ) are met. The special test and certification program Trusted Site Infrastructure from TÜViT can, for example, be used to perform a detailed examination of the availability of the IT infrastructure also from a physical point of view in order to assess the aspects relating to site structure and supply systems.
19 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 19 of Operating conditions for the hardware components of the LTA solution The operating conditions (such as, for example, air-conditioned rooms) are determined by the requirements specified for the hardware components by the manufacturer, and these requirements shall be fulfilled Operating conditions for the software components of the LTA solution The operating conditions (such as, for example, certain operating systems) are determined by the requirements specified for the software components by the manufacturer, and these requirements shall be fulfilled Occupational health and safety It shall be ensured that the requisite occupational health and safety measures, e. g. workstation design and arrangement, are implemented and complied with Operating procedures The operating procedures for LTA operation relate to working with the LTA solution and are normally based on the general procedures for IT operation.

It is recommended that restarting the system be practiced at regular intervals using a test system Recovery A process role responsible for initiating a recovery of the LTA solution shall be defined, and an operating procedure or a disaster recovery plan shall be provided. It is recommended that recovery be practiced at regular intervals using a test system. 3.6 Assessment area 6: Processes All the processes associated with the LTA solution that are relevant to the handling and processing of content information and administrative data are described in VDA Only the processes not attributed to the ongoing technical and organizational operation of an archive according to section 3.5 are described in this section. The main assessment criteria of the LTA processes are listed in the following sections Ingest of content information The consistency of the content of the data to be archived (SIP) and, optionally, storage of presentation information for this data shall be ensured during the ingest process (AIP), and proof shall be provided. The technical requirements are determined by the use cases for future data usage (VDA ) Handling digital content information and administrative data The digital content information and administrative data shall be handled in accordance with the recommendations in VDA including any company-specific process customizing. This includes the design of the processes used to prepare the data for long-term archival, the archiving of the data itself and the steps required to access and reprocess the archived data in order to assure an adequate level of quality for the data and documents. Operating procedures and process specifications for the roles defined in VDA shall be created and submitted. The handling of the digital content information and administrative data shall also be taken into consideration by IT security (3.4), including the authorization concept Quality assurance measures The measures taken to safeguard the assessment aspects (2.1) by means of validation mechanisms (VDA ) shall be described, and proof of their error-free functioning shall be provided. This proof can be provided by suitable procedures (e. g. checksum procedures, random checks, plausibility checks), as well as by technical and organizational measures.
21 VDA Recommendation 4958 T 4 1st edition, June 2007 Page 21 of Access and processing of content information and administrative data Regulations and functions regarding access to and processing of data that apply to IT solutions (e. g. check-in/check-out mechanisms, locking mechanisms, write permissions, logging) also apply to the LTA solution. They shall be described and their correct functioning shall be validated by spot checks, e. g. in the audit Version control for content information Changes to content information are subject to version control. A description of how versioning is performed and what nomenclature is used shall be included Logging Changes to administrative data shall be logged for a complete change history. Changes to index information and documents shall be indicated. A description of how logging is performed and what nomenclature is used shall be included. If, as the case may be, logging of any changes made is only to be performed for a subset of the administrative data, this shall be specified and described as it pertains to the company in question Data transfer of content information and administrative data Significant data transfer steps (forwarding) of content information and administrative data shall be logged. This includes, at a minimum, data transfer involving the process roles data creator, preparer, archive and consumer Granting and logging authorizations Organizational stipulations for the granting of authorizations by authorized persons shall be made, and appropriate procedures shall ensure compliance with these stipulations. These types of authorizations can, for example, be granted for dissemination of content information to consumers access to information that has a security rating the deleting of documents in the archive The stipulations relating to the granting of authorizations are normally reflected in the guidelines governing IT security (3.4). It shall be possible at all times to determine which authorized person granted which authorization at what point in time Immutability The LTA process (VDA ) shall ensure that the content information cannot be changed and this shall be verified by means of certification Logging archiving operations To ensure transparency, every archiving operation (Archival Storage process step in VDA ) shall be logged Retrieval time for archived data It shall be ensured, from both a technical and organizational point of view, that the archived data can be located and retrieved quickly enough. The retrieval of information from the archive refers to complete documentation pursuant to mandatory archiving and applies, at a minimum, to all the documents relevant for (product) approval. Spot checks should be performed at regular intervals to ensure retrieval.
