    10 Most plant engineers are familiar with the issue of transferring the contents of a CAD drawing from one authoring system to another.  But this is not a new issue at all; it goes back several decades to when we first used computers in engineering.  The huge demand for free and easy exchange of plant, and other, information has spawned a number of initiatives.

    1616== How we Store and Exchange Plant Information == 
    17 Interoperability of plant information between proprietary systems became an issue almost from the advent of CAD in the 1950s.  There are many organizations dedicated to interoperability in just about every industry.  Interoperability in the plant industry started in the mid twentieth century U.S. defense department, and expanded to include aerospace, automotive, and plant.  Included here are some of the more significant initiatives.

    3131=== The Initial Graphics Exchange Specification (IGES) === 
     32 
    3233Computer based graphics systems started appearing in the mid 1950s in the U.S. Defense industry.  By the 1970s the Department of Defense wanted a neutral format that would allow the digital exchange of information between CAD systems.  The IGES project was started in 1979 by a group of CAD users and vendors, with the support of the National Bureau of Standards (NBS), now known as the National Institute of Science and Technology (NIST).  In 1980 the NBS published what they called the Digital Representation for Communication of Product .  This standard was also published by ASME/ANSI as Y14.26M, which is how many military standards refer to it.

    4243=== Standard for the Exchange of Product Data (STEP) === 
     44 
    4345The development of STEP started in 1984.  The objective was to provide a means of describing product data throughout its lifecycle, independent of any particular computer system.

    5153  * The ability to store temporal, or time-related information.  Recording changes to a processing plant over its lifetime is outside the scope of STEP. 
    5254 
    53 In 1994 STEP was issued as ISO 10303 Industrial systems and integration - Product data representation and exchange. 
     55In 1994 STEP was issued as ISO 10303 "Industrial systems and integration - Product data representation and exchange".

    6567=== PlantSTEP === 
     68 
    6669PlantSTEP was active in the 1990s.  It was a consortium of organizations with the purpose of developing and exchanging standards based on ISO 10303.  The hope is that these standards will enable concurrent engineering, design, construction, and operation of large facilities by allowing full information sharing among all project contributors.  The vision is for all parties to be able to use their own tools and work methods, but to be able to share appropriate information between them seamlessly.

    6871The list of specific benefits mirrors that of all interoperability initiatives: 
    6972 
    70  * Reuse data 
    71  * Share and exchange data between multiple participants with full integrity and fidelity 
    72  * Lifetime data availability and retrieval at varying levels of detail 
    73  * Owners can receive consistent deliverables from vendors, engineers, and constructors 
    74  * Allows easier plant modification over life of facility 
     73 * The reusabilty of data. 
     74 * The ability to share and exchange data between multiple participants with full integrity and fidelity. 
     75 * The availability of data for retrieval at varying levels of detail over the lifetime of the facility. 
     76 * Owners can receive consistent deliverables from vendors, engineers, and constructors. 
     77 * It allows easier plant modification over the life of the facility.
