GEIA-927 - Common Data Schema for Complex Systems
GEIA-927 - Common Data Schema for Complex Systems
Abstract
GEIA-927 is being developed as a US reference model to achieve interoperability among IT systems for complex engineer-to-order systems, products and processes over the life cycle; building on many of today's data standards, integrating best-in-class data models from these partial solutions with the GEIA-927 top-level integration model.
It is not intended to replace the existing information models, but to indicate how they can work together.

Business Justification
The GEIA-927 effort is now driven by LOGSA and is intended to assist in their business integration activities.
Description of activity/deliverables
Activities
• GEIA-927 has integrated an early draft of ISO 10303 (STEP) AP233 Systems Engineering, DoD Corporate Logistics Data Model (partial) and ISO 10303 AP212 Electrotechnical Design and Installation, the draft of ISO 10303 Product Life Cycle Support (PLCS) AP 239 and the US EIA-836 Configuration Management for Integration into its model.
• It is planned to incorporate a range of additional standards into the reference model including Logistics Support Analysis Record (LSAR), Level of Repair Analysis (COMPASS), Life Cycle Cost Analysis (CASA), Post Fielding Support Analysis (PFSA) and STEP AP214.
• GEIA-STD-0007 is a specification for a Logistics Product Data Implementation model, planned as the first implementation of the GEIA-927 reference model, focused on logistics information, as requested by the NDIA SEC LCS. Specifically, the data model contained in the former MIL-STD-1388-2B, Logistics Support Analysis Record (LSAR) will be transformed into GEIA-STD-0007. The objectives of the standard are to fill the void for delivery/exchange of logistics information.
Deliverables
• US national standard GEIA-927
• GEIA-STD-0007
Assumptions
• The GEIA-927 team will integrate the published version of the ISO PLCS standard into the GEIA-927 model, and also 10303-233 when it becomes available, so that the work is not divergent
• GEIA-STD-0007 will be developed as a PLCS DEX, so that it is not restricted to US-only use. The DEX is planned to supersede the GEIA standard.
Business benefits/barriers
1. Deployment of a US-only specification will act as a barrier to trade, and drive costs into the supply chain.
2. GEIA-927 may have some use as a reference model in bridging between product information and transactional data for logistics - this may complement the PLCS initiative, but this is yet to be validated.

Enterprise data and metadata
EEIC Action Plan
1. EEIC members will actively participate with their company representatives in the GEIA-927 group to ensure that the development of EIA-927 becomes interoperable with standards such as PLCS, including:
• Use of the published version of PLCS
• Eliminate duplicate information models within EIA-927 model eg EIA-836, which is covered by PLCS
• Possible exploitation as an integration framework for bridging between product information and business transactions
2. EEIC to actively participate in the NCO-CDE activity which is recommending that GEIA-STD-0007 be developed as a PLCS DEX
EEIC Status (updated May 2007)
• GEIA-927 accepted. Close coordination has now been established between the project and the ISO TC184 SC4 activity to align the document with the published ISO standards. This is in accordance with the recommendations of the NCO-CDE project.
• EEIC notes that the STEP standards included in GEIA-927 are Application Protocols (see STEP blip). They represent views of an integrated model, but the GEIA approach does not take account of this underlying integration, and attempts to re-integrate the views. This has led to some divergences from the ISO standards.
• Second draft of GEIA-STD-0007 accepted at ballot. LOGSA now planning to develop DEX version.
