Long-term Archiving and Retrieval (LOTAR)

Term

since 2003

Tasks

LOTAR is a project managed under the AIA, ASD-Stan, PDES, Inc. and prostep ivip consortiums. The project goal is to develop, implement, test, pilot, publish and maintain standards designed to provide the capability to archive and retrieve digital product and technical information, including CAD, PDM, Composites, Electrical Harness, CAE and 3D Visualization data, in a standard form that can be read and reused throughout the product lifecycle, independent of changes in the IT environment originally used. The multi-part standard covers the information content as well as the processes required to ingest, store, administer, manage and access the information. It is published as EN/NAS-9300.

Milestones 2019

The review and update process for the LOTAR Basic & Common Process Parts was launched. The Mechanical working group commenced work on the manufacturing feature domain parts, focusing on structural joints. The PDM WG mapped concepts defined in Part 210 to the STEP Core Model for AP242 and AP239 and prepared the “as designed/as planned” use case for the PDM IF. The Composites validation property definitions were extended. The Electrical Harness team supported the launch of the associated Interoperability Forum (EWIS IF) and continued development of the 400 series LOTAR parts. The MBSE WG defined a use case for archiving analytical models with associated manifest and outlined ideas for industry engagement. The EAS WG defined further FEA Validation Properties and successfully demonstrated an AP209-based exchange at the NAFEMS World Congress.

Outlook 2020

The LOTAR project will strengthen its ties with EASA and FAA to ensure adoption of the standard. The Mechanical WG will plan the first pilots involving holes and fasteners. The PDM team will complete Parts 210 and 230, work on Functional Architecture and Metadata for Archival Packages and continue collaboration with the PDM IF. The Composites WG will submit the first LOTAR parts in their domain for external ballot. The Electrical Harness team will contribute to the test rounds of the EWIS IF. In the MBSE domain, completion of part 500 for Fundamentals and Concepts is planned as well as a draft of part 520 for Analytical Models. For EAS, pilot studies are planned to expand the number and scope of AP209 implementations together with the CAE IF; and the LOTAR Parts 600 and 620 will be finalized.
