Aerospace series - LOTAR - LOng Term Archiving and Retrieval of digital technical product documentation such as 3D CAD and PDM data - Part 120: CAD 3D explicit geometry with graphic product and manufacturing information

1.1 Introduction
This document defines the requirements for the long term digital preservation of the presentation of Product and Manufacturing Information (PMI) with their possible links to the 3D explicit shape and geometry of single CAD parts. The goal is to preserve this 3D information with respect to the geometry and related PMI produced by the original CAD system, following the principles laid down in EN 9300 003 “Fundamentals and Concepts”.
The requirements of EN 9300 110 “CAD mechanical 3D explicit geometry information” about the preservation of the 3D explicit shape shall apply within this document.
The meaning of terms "Presentation" and "Representation", defined in the EN 9300 100 “Common concepts for Long term archiving and retrieval of CAD 3D mechanical information” is required to understand this EN 9300 document.
1.2 In scope
The following outlines the total scope of this document:
- the Presentation of 3D geometrical dimension and tolerance, and 3D annotation attributes;
- their possible semantic links with 3D Geometric shape;
- User Defined Attributes: that are assigned to 3D geometric entities or at the part level.
For the purpose of this document, the semantic definition is at the level that supports associative “Cross-highlighting”, to illustrate the portion of the geometry to which a PMI element applies.
In this version, the technology used to preserve this 3D information is based on polyline and tessellated presentation. Polyline presentation is a conversion to lines and curves of all 3D annotations by the STEP interfaces of the CAD system, including validation properties.  Tessellated presentation is a conversion to tessellated curves and tessellated faces. The main use cases are the Certification and Product Liability of static information, however, re-use is also possible after the deletion of previous PMI and creation of new PMI (refer to clause 3 for definition).
1.3 Out of scope
The following is outside the scope:
- machine-interpretable PMI “Representation”;
- how to preserve additional information:
- - property rights;
- -form features;
- -machining features;
- CAD Assemblies.

Aeronavtika - LOTAR - Dolgotrajno arhiviranje in iskanje digitalne tehnične dokumentacije o izdelkih, kot so podatki o 3D, CAD in PDM - 120. del: CAD 3D eksplicitne informacije o geometriji z grafičnim izdelkom in izdelavo

1.1 Uvod
Ta dokument določa zahteve za dolgoročno digitalno shranjevanje predstavitve informacij o grafičnem izdelku in proizvodnji (PMI) z morebitnimi povezavami do 3D eksplicitne oblike in geometrije posameznih delov CAD. Cilj je ohraniti 3D informacije glede na geometrijo ter povezane informacije o grafičnem izdelku in proizvodnji, ki jih proizvede prvotni sistem CAD, v skladu z načeli, določenimi v standardu EN 9300-003 »Osnove in pojmi«.
V tem dokumentu je treba upoštevati zahteve standarda EN 9300-110 »CAD mehanske 3D eksplicitne informacije o geometriji« v zvezi s shranjevanjem 3D eksplicitne oblike.
Za razumevanje tega dokumenta EN 9300 je potreben pomen izrazov »predstavitev« in »prikaz«, opredeljenih v standardu EN 9300-100 »Splošni pojmi za dolgoročno arhiviranje in pridobivanje CAD 3D mehanskih informacij«.
1.2 Znotraj področja uporabe
Naslednje opisuje celotno področje uporabe tega dokumenta:
– predstavitev 3D geometrijskih dimenzij in toleranc ter 3D atributov opomb;
– njihove morebitne semantične povezave s 3D geometrijsko obliko;
– uporabniško določeni atributi, ki so dodeljeni 3D geometrijskim entitetam ali na ravni dela.
Za namene tega dokumenta je semantična definicija na ravni, ki podpira asociativno »navzkrižno poudarjanje« za ponazoritev dela geometrije, za katerega se uporablja element informacij o grafičnem izdelku in proizvodnji.
V tej različici tehnologija, ki se uporablja za shranjevanje 3D informacij, temelji na lomljeni in mozaični predstavitvi. Lomljena predstavitev je pretvorba v črte in krivulje vseh 3D opomb prek vmesnikov STEP sistema CAD, vključno s potrjevalnimi lastnostmi.  Mozaična predstavitev je pretvorba v mozaične krivulje in mozaične ploščice. Glavna primera uporabe sta certificiranje in odgovornost za izdelek v okviru statičnih informacij, vendar je možna tudi vnovična uporaba po izbrisu prejšnjih oziroma ustvarjanju novih informacij o grafičnem izdelku in proizvodnji (za definicijo glej točko 3).
1.3 Zunaj področja uporabe
Naslednje ne spada na področje uporabe:
– »prikaz« strojno berljivih informacij o grafičnem izdelku in proizvodnji;
– način shranjevanja dodatnih informacij;
– lastninske pravice;
– oblikovne lastnosti;
– lastnosti strojne obdelave;
– sestavi CAD.

SIST EN 9300-125:2024

1.1 Introduction
This document defines the requirements for the long-term digital preservation of the presentation of Product and Manufacturing Information (PMI) with their possible links to the 3D explicit shape and geometry of CAD assembly structure. The goal is to preserve this 3D information, without loss, with respect to the geometry produced by the original CAD system, following the principles laid down in EN 9300 003 “Fundamentals and Concepts”.
This will allow the retrieval of the assembly structure including the placement information.
This standard extends EN 9300-115 “Explicit CAD Assembly Structure” by including assembly level PMI.
PMI for the assembly structure can be recorded in the same file as the geometry, can be in a nested assembly structure or the PMI will be contained in its own separate file (Side-Car).
The PMI elements shall be presented on the graphic level only (i.e. polyline, tessellated).
1.2 Out of scope
The following is outside the scope:
- The archiving of assembly Form Features.
- Semantic PMI representation is out of scope for this document.
- The geometry defined at assembly level is out of scope for this document.
(This document covers PMI at the assembly level only.)

Aerospace series - LOTAR -LOng Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Part 002: Requirements
SIST EN 9300-002:2018

This document is a part of the EN 9300 Series. This document addresses requirements for the long term archiving of digital product information, applicable to the international aerospace industry.
Data shall be available to meet regulatory, legal, contractual and business requirements.
Initially, this document sums up the main business requirements for long term archiving of digital product data. Although these requirements are not in themselves normative, when making data available over an extended period, it is a fundamental principle that the contextual data needed to interpret the data is also available.
This document uses the OAIS reference model to provide comparability with other approaches to keeping information available. However, OAIS is a standard reference model for comparison, not a standard for implementation. Consequently, this document defines requirements for processes (and associated technologies) intended to make data available for the life of a product, and does so in terms of the OAIS model.
In dealing with traditional media, the differences between substantial change and unimportant “surface” change are generally self-evident. For example, the yellowing of paper over time, or the encrustation of a gravestone with lichen do not lose the information contained, whereas the loss of pages of a document, or the erosion of the stone do so, and archiving focusses on the preservation of the medium. For digital product data, the medium is unimportant, but the content can be corrupted. The subject of the (many) remaining parts of this standard is the identification of the information that shall be uncorrupted if digital product data is to be usable in the future, and the consequent refinement of processes and procedures to insure this.
This document addresses, archiving of digital product data required for product definition, such as in three dimensional representations a tolerances, material properties, manufacturing data, etc. specification call-outs, product structure and configuration control data, etc. Other parts of the EN 9300 standards will cover more specifically the long term archiving of, for example, composites, electrical systems, product analyses and product simulation information.
This document also addresses managing the evolution of technologies required to ensure the availability and usability of the data for the required archiving period.
This document is not intended to incorporate company specific requirements and does not dictate specific organizational structures within a company. This document does not specify a design or an implementation of an archive system. Actual implementations may distribute responsibilities or break out functionality differently.
This document assumes that all requirements for configuration management of the product data are in place and therefore are not specifically described in this document.
If an organization chooses to implement requirements beyond those outlined in this requirements document, those additional requirements shall not conflict or negatively impact the requirements contained in this document.
Purpose:
This document establishes legal and other business requirements for processes intended to preserve digital data. Data needs to be stored and maintained so that data is retrievable and usable for the required archiving period. In addition, for some business requirements, data needs to be authentically preserved and accessed.
This standard is intended to allow for different implementations based on a company’s specific business environment.

Aerospace series - LOTAR - LOng Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Part 200: Common Concepts for LOng Term Archiving and Retrieval of Product Structure Information
SIST EN 9300-200:2018

2.1   PDM data in EN 9300 context
In most modern industrial environments, product data is maintained and managed using product data management (PDM) systems. In general, these systems:
-   Manage the use of the primary technical data contained, for example, in CAD models and documents;
-   Allow organization of primary technical data into structures to represent the relevant products;
-   Support definition and maintenance processes for products.
Within the EN 9300 context, several domain specific parts address LTA&R for the primary technical data (e.g. CAD, CAx, Documents) as generated by the relevant technical "authoring" systems. The EN 9300 2xx series provides information for LTA&R of product management data for the relevant documents, structures and processes.
NOTE   The terms "PDM data" and "product management data" are synonymous.
This is illustrated in the Figure below.
(...)
Figure 1 - PDM Data and Primary Technical Data
2.2   Objectives and scope of application
This part covers long term archiving (LTA&R) for product management data and relevant process related information (e.g. product structure requirements). Regarding process related information, only the process results are considered in scope as these have stable and static characteristics. The workflow used to create the information is not in scope. The resulting information, e.g. change authorization document, approvals/signatures, CAD models, attribute data, are in scope.
Product management data closely reflects the local business and data handling processes of each company. Therefore, an open standard can define only a common generic subset of the overall requirements. Other data that are only of local relevance or dependent on the local application environment are defined by local procedures. For each application environment, the complete set of standards, methods, and procedures related to the archived product management data shall be defined and documented by open standards, industry standards, or company standards and procedures. It is strongly recommended to use open standards whenever possible to ease data exchange, sharing, archiving, and ability to audit.
Three main objectives for LTA&R of product management data are:
-   enable the proper retrieval of archived primary technical data when performing queries relative to product structure, relationships, effectivity, status, etc.;
-   preserving the links between primary technical data and the associated product management data;
-   providing all relevant properties of primary technical data as contained within the associated product management data.
2.2.1   Architecture Definition
The product management data and the primary technical data may be managed in different environments (e.g. a database system for the product management data and a file system for the primary technical data with a reference in the database to the unique identifier and location for the file). In many cases, the primary technical data are held by the primary generating systems (e.g. CAD, systems engineering tool set) attached to a PDM backbone architecture.
The relationship between product management data and primary technical data is typically established by referencing mechanisms. The referencing mechanisms and the systems managing them shall be taken into account when archiving.
This can be done by describing the complete architecture of systems involved in the management of the relevant information and by defining common system requirements and procedures, such as synchronization, applied quality level, security requirements, and auditing. The overall capability of the architecture requires all systems within the architecture to comply with the common requirements.
The complete architecture definition shall comply with requirements defined in the applicable EN 9300 common process parts.
