28、 purpose for this change is to add Part 28 as an allowable Implementation method in addition to Part 21. Replace the first paragraph with the following text. The implementation method defines what types of exchange behavior are required with respect to this part of ISO 10303. Conformance to this par
29、t of ISO 10303 shall be realized in an exchange structure. The file format shall be encoded according to the syntax and EXPRESS language mapping defined in either ISO 10303-21 or ISO 10303-28 and in the AIM defined in Annex A of this part of ISO 10303. The header exchange structure shall identify us
30、e of this part of ISO 10303 by the schema name plant_spatial_configuration. Page 1402, Annex C Edition 2 of ISO 10303-21 added the capability to identify the particular Application protocol Conformance Class to which an exchange file conforms. The purpose for this change is to add the specification
31、of values for this part of ISO 10303 to utilize that capability. Insert the following text after the existing paragraph. C.1 General requirements For various reasons, some entities may not be completely exported into an exchange structure. There may be mandatory information in the AIM that has no co
32、rrespondence in the ARM. Sometimes an application may not maintain all the information that is anticipated for the data exchange. Other times, ISO 10303-227:2005/Cor.1:2008 (E) 8 ISO 2008 All rights reserved the information may be maintained by a sending system but not included in the data exchange.
33、 Nevertheless, the preprocessor must provide values for all mandatory attributes in an exchange file. When no data is provided by a sending system for a required string value, the preprocessor shall use .UNUSED. or the empty string . To further indicate the reason why no data is provided, the follow
34、ing convention shall be used: An empty string indicates user data managed by the sending system but not provided for data exchange. As receiving system software may depend upon population of realistic data values for required attributes, use of empty strings is discouraged; A string with a value of
35、.UNUSED. indicates user data in a mandatory attribute that is not managed by the sending system, is not known at the time of the data exchange, or is mandatory AIM information that has no correspondence in the ARM; $ is used in the physical file if an optional attribute is not instantiated. C.2 Requ
36、irements specific to the implementation method defined in ISO 10303-21 If the implementation method is ISO 10303-21, the file format shall be encoded according to the syntax and EXPRESS language mapping defined in ISO 10303-21. The FILE_SCHEMA element of the header shall specify the name of the EXPR
37、ESS schema used and include its object information identifier (see Annex E). EXAMPLE The instance below identifies the ship_arrangement schema: FILE_SCHEMA ( PLANT_SPATIAL_CONFIGURATION 1 0 10303 227 3 1 1 ) C.3 Requirements specific to the implementation method defined in Edition 2 of ISO 10303-21
38、ISO 10303-21:2002 added the capability to specify the particular Conformance Class to which the Data section of an exchange file conforms. Exchange files conforming to the 2002 Edition of ISO 10303-21 shall contain one or more instances of the entity Section_context in the Header section of the file
39、. Example SECTION_CONTEXT ($,(CC1); If a single Data section is included in the exchange file, a single instance of the entity Section_context shall be included, and the value of the attribute section_context.section shall be $. The set of values of the attribute section_context.context_identifiers
40、shall contain a single value to identify the particular Application protocol Conformance Class to which the data conforms. The attribute value shall be one of: CC1; CC2; CC3; CC4; CC5; ISO 10303-227:2005/Cor.1:2008 (E) ISO 2008 All rights reserved 9 CC6; CC7; CC8; CC9; CC10; CC11. Page 1405, E.1 Rep
41、lace the object identifier with the following text. iso standard 10303 part(227) version(3) Page 1405, E.2 Replace the sublause in its entirety with the following text. E.2 Schema identification To provide for unambiguous identification of the plant_spatial_configuration expanded schema in an open i
42、nformation system, the object identifier iso standard 10303 part(227) version(3) object(1) plant-spatial- configuration(1) is assigned to the plant_spatial_configuration expanded schema (see annex A). The meaning of this value is defined in ISO/IEC 8824-1, and is described in ISO 10303-1. To provide
43、 for unambiguous identification of the plant_spatial_configuration short form schema in an open information system, the object identifier iso standard 10303 part(227) version(3) object(1) plant-spatial- configuration-schema(2) is assigned to the plant_spatial_configuration short form schema (see 5.2). The meaning of this value is defined in ISO/IEC 8824-1, and is described in ISO 10303-1.
