The wo

    10、rk of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governm

    11、ental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The ma

    12、in task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Att

    16、t of ISO 25297, dealing with the Neutral Optical Data Interchange Format (NODIF), is the International Standard that describes the way optical information is transferred from one computer-aided-design program (CAD, CAE, CAM) to another, in a machine-independent and language-independent format.ISO 10

    17、303 (all parts) is the International Standard for Exchange of Product model data (STEP) that describes the computer-interpretable representation and exchange of product data. Its objective is to provide a neutral mechanism capable of describing any product data throughout the life cycle of the produ

    18、ct, independent of any particular system. This description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and for archiving. ISO 10303 (all parts) has been designed to support an extensive domain of product data-communication

    19、requirements, i.e. all product data necessary to completely define any product for all applications over the products life cycle.STEP is organized in a series of parts, each published separately. Each part falls into one of the following categories: descriptive methods, integrated resources, applica

    20、tion integrated constructs, application protocols, abstract test suites, implementation methods and conformance testing. The series is described in ISO 10303-1.A fundamental concept is the definition of the application protocol (AP), which is the mechanism for specifying information requirements and

    21、 for ensuring reliable communication. An application protocol defines the context, scope and information requirements for a particular product and specifies the resource constructs required to satisfy these requirements. Application protocols employ three types of information models:a) an applicatio

    22、n activity model (AAM), which describes the activities and processes that use and produce the product data in a specific application context;b) an application reference model (ARM), which defines the terminology within the application context and specifies the conceptual structures and constraints t

    23、hat are used to describe the information requirements for an application;c) an application interpreted model (AIM), which is a model of selected integrated resources that are constrained, specialized or completed to satisfy the information requirements of the ARM.This part of ISO 25297 for NODIF is

    24、intended to conform to the requirements of ISO 10303 (all parts) as a member of the application protocol series. ISO 2012 All rights reserved vBS ISO 25297-1:2012BS ISO 25297-1:2012Optics and photonics Electronic exchange of optical data Part 1: NODIF information model1 ScopeThis part of ISO 25297 s

    25、pecifies the information requirements for optical systems and parts, and provides an information model to support the processes of optical design, optical evaluation and analysis for these optical systems and parts when using computers with CAD and CAE.NOTE Generally, an optical system means an opti

    26、cal unit as an optical product, which performs optical functions, and is composed of optical elements and the barrels in which these elements are mounted. In this part of ISO 25297, an optical system is a collection of optical parts and optical assemblies, e.g. the viewfinder system or the taking le

    27、ns system of a leaf shutter camera.This information model adds the data peculiar to optical design specification based on STEP to ISO 10303 (all parts). The additional information is product specification information, optical design information, optical evaluation information and analysis informatio
