Purpose of this presentation:
What an IPDE is and why the sharing of data is important
An overview of the SCIM and how it can be used within an IPDE
The ability of the SCIM to allow the sharing of data between organizations
Factors affecting the implementation of the SCIM

A Standard is required for this exchange of product data
• ISO 10303 is the international standard
• Informally known as “STEP ”:
(STandard for The Exchange of Product Model Data)
So, why not use the STEP ISO Standard directly ?
NATIONAL SHIPBUILDING RESEARCH PROGRAM 13
The STEP Series of ISO Standards support many industries

• The SCIM is based on shipbuilding portions of the Step Standards
• The SCIM defines the requirements and XML data model for Ship data exchange
• This XML Data defines the minimum set of entities & attributes that must be available for applications supported by an IPDE…
• …and for sharing with business partners and the Navy
The SCIM satisfies the STEP Requirements

• SCIM Documented in XML
• This allows for development of IPDE Data Translators In-House
• XML is standard method for accessing non-graphical data

The SCIM specification is…
Fully documented and user-friendly
Usable by shipyard personnel, including non-IT specialists
Capable of validation
Suitable for contractual specification
Of practical use for agreements between shipbuilder and CAD System vendors

• Each of these SCIM Chapters has a corresponding XML Schema

Importance of the Ship Common Information Model
Allows shipyards to move data between different pieces of their Integrated Product Data Environments (IPDE)
Allows shipyards to exchange data with each other and the Navy
Necessary due to the Navy’s practice of requiring multiple-shipyard design and build contracts, and…
… because of the short lifespan of computer systems and software compared to the life of a ship
NATIONAL SHIPBUILDING RESEARCH PROGRAM 2525NATIONAL SHIPBUILDING RESEARCH PROGRAM
Advantages to implementing SCIM at YOUR Shipyard
Uses inexpensive or free XML tools rather than expensive STEP EXPRESS language toolkits
Uses existing XML application programming interfaces to shipyard PDM and CAD tools
Minimal introductory training needed for shipyard IT personnel to quickly implement XML-based translators
