Aerospace series - LOTAR - Long Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data - Part 004: Description methods

This European Standard presents methods which are divided into four main categories:
1)   scope and scenario description;
2)   process description;
3)   data;
4)   system architecture.
For scope and scenario description, the modelling methods are based on Unified Modelling Language (UML) Use Case diagrams. The process descriptions are done using Simplified Activity diagrams. Data modules are described by Express G diagrams. Rules and constraints are described via Express-Where-Rules. Further descriptions, for example, for a data dictionary, are based on tabular forms.
To support the development of a system architecture, the modelling method of UML Package diagrams is used.

Luft- und Raumfahrt - LOTAR - Langzeit-Archivierung und -Bereitstellung digitaler technischer Produktdokumentationen, wie zum Beispiel von 3D-, CAD- und PDM-Daten - Teil 004: Beschreibungsmethoden

Diese Europäische Norm legt die Verfahren, die in vier Hauptkategorien eingeteilt sind, dar:
1)   Beschreibung von Anwendungsbereich und Szenario;
2)   Prozessbeschreibung;
3)   Daten;
4)   Systemarchitektur.
Die Modellierungsverfahren zur Beschreibung von Anwendungsbereich und Szenario beruhen auf Falldia-grammen in der Unified Modelling Language (UML). Prozessbeschreibungen erfolgen mittels vereinfachter Aktivitätsdiagramme. Datenmodule werden durch Express-G-Diagramme beschrieben. Regel und Einschrän¬kungen werden über Express-Where-Regeln beschrieben. Weitere Beschreibungen, z. B. für ein Datenwörter¬buch, beruhen auf Tabellenformularen.
Die Entwicklung einer Systemarchitektur wird durch Modellierung mit UML-Package-Diagrammen unterstützt.

Overview

EN 9300-004:2013 is a CEN European Standard in the Aerospace series (LOTAR) that defines description methods for Long Term Archiving and Retrieval (LOTAR) of digital technical product documentation - including 3D models, CAD and PDM data. The standard prescribes modelling and documentation techniques to ensure consistent, unambiguous descriptions of scope, processes, data and system architecture for archiving solutions in the aerospace domain.

Key topics

• Scope & scenario modelling: Use of UML Use Case diagrams (UML 1.4) to capture high-level functionality, actors and scenario permutations relevant to archiving and retrieval.
• Process description: Use of Simplified Activity diagrams (UML/IDEF0-inspired) with swim lanes, milestones and hierarchical decomposition to document workflows, decisions and supporting processes. Process models are expected to be deliverable in an HTML representation for navigation and traceability.
• Data modelling: Graphical and formal data definitions using EXPRESS-G diagrams (ISO 10303-11 based) to visualise entities, relationships and cardinality; and EXPRESS WHERE rules to specify constraints and rules. A data dictionary in tabular form documents entities, attributes and recommended usage.
• System architecture: Use of UML Package diagrams to describe modular architecture and component boundaries supporting LOTAR implementations.
• Applicability & deliverables: Applicable to archived records that define archiving requirements and data quality requirements; supports existing and legacy product records.

Practical applications

• Establishing a repeatable, standards-based method to document how CAD/3D/PDM data will be archived and retrieved over long lifecycles.
• Creating machine-readable, traceable process and data specifications for system integrators, PDM administrators and archive implementers.
• Supporting procurement and contractual requirements by providing consistent use-case, process and data models as part of LOTAR deliverables.
• Enabling quality assurance, interoperability and future-proof retrieval of aerospace technical product data.

Who should use this standard

• Aerospace manufacturers and suppliers working on long-term preservation of CAD, 3D and PDM data
• Systems architects, data modelers and IT integrators implementing LOTAR solutions
• PDM/PLM administrators, configuration managers and archivists responsible for compliance and data governance
• Contracting authorities specifying archival formats, processes and system requirements

Related standards

• EN 9300-007 (LOTAR - Terms and References)
• ISO 10303-11 (EXPRESS language reference) and related STEP APs (e.g., AP214) for recommended archiving data formats

5 Method for scope/scenario description: UML Use Case diagram
The Unified Modelling Language (UML) is an industry-standard language for specifying, visualising,
constructing, and documenting software systems. It simplifies the complex process of software design by
making a "blueprint" for construction. The diagrams are realised with the specification of UML version 1.4.
According to UML definitions, Use Case diagrams identify the functionality provided by the system (use cases),
the users who interact with the system (actors), and the association between users and functionality. Normally
Use Cases are used in the analysis phase of software development to articulate the high
