This section is GB/T Part of 2,816,656.

GB/T 16656 is identical with this part of ISO 10303-28:2007 "Industrial automation systems and integration - Product data representation and cross in other implementation method Part 28. EXPRESS schema and XML expression data (using XML mode) ", its technical content and conclusions Structure and ISO 10303-28:2007 consistent. For ease of use, made the following editorial changes.

a) by deleting the ISO foreword;

b) For each underlined in bold for EXPRESS English language to describe the entity names, attribute names and function names, etc., in order to maintain its English original intent, in this section, uses its English name, only when it is used as the title, we have added in front of the English name its home type described.

This section of the Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F for the normative appendix, Appendix G is an informative annex.

This part is proposed by China Machinery Industry Federation.

This part of the automation systems and integration by the National Standardization Technical Committee (SAC/TC159) centralized.

This part mainly drafted by. China National Institute of Standardization.

Introduction

GB/T 16656 is a technical standard for computer interpretable expression product information and product data exchange. Its purpose is to Product Lifecycle provides an independent of any particular system, product data can describe neutral mechanism. Its function is not only suitable description for neutral file exchange, but also to achieve the foundation and sharing product databases and archiving.

GB/T 16656 in this part of the series is an implementation method. GB/T 16656 provisions of this part of the EXPRESS language (GB/T 16656.11 defined) and in line with patterns described EXPRESS data model expressed as XML documents, so You can use the XML support XML technology and a variety of software tools to exchange product data EXPRESS described, but also for this these products are used in XML data set expression "electronic commerce" business transaction.

In order to understand the technical content GB/T 16656 in this section, users should understand EXPRESS language, XML schema languages, XML in XML and related standards.

For the EXPRESS mode corresponding expression data, this part of GB/T 16656 using XML schema language formally specified in line with this pattern of exchange of the document structure. Some elements of the document expresses the accord EXPRESS mode data collection, GB/T 16656 Type defined in this part of the XML schema and the EXPRESS mode description derived element declaration to describe the junction of these elements Structure. GB/T 16656 in this section also provides for the exported XML pattern matching XML data encoding rules. In order to meet Meet the needs of various contradictions exchange documents produced, GB/T 16656 in this section also defines the specific configuration instructions for explaining export XML schema structure and an optional selectable coding rules.

note.

GB/T 16656 purpose of this part is to implement the software, when software development is based on non-ISO translated into the official language of this section , It will lead to incompatibilities between the computer communications. It recommends that any development software should be based on ISO official language of the text.

Industrial automation systems and integration Product data representation and exchange Part 28. Implementation. EXPRESS mode and XML expression data (using XML Schema)

1 Scope

This section GB/T 16656 specifies how to use the Extensible Markup Language (XML) data description language expressed EXPRESS (GB/T 16656.11) patterns described and in line with the pattern data. This section GB/T 16656 by specifying the full file exchange XML schema corresponding to the description EXPRESS mode switches set additional XML data model formally defines the XML expression.

This section applies to.

Format Description --- contains EXPRESS mode and in line with the pattern data of the XML document (see Chapter 5);

--- For any EXPRESS mode, which describes the pattern corresponding XML schema, and formally describe that match the pattern XML data expression (see Chapter 6);

--- EXPRESS data type of the value expression to describe the content of the XML elements and XML attribute values \u200b\u200b(see Chapter 9);

--- Description for explaining a configurable set of instructions conform EXPRESS mode of data collection options structure expressed in XML (see Chapter 10).

This section does not apply to.

--- Description relies on XML schema declaration or define any particular semantic object EXPRESS mode, as distinguished from EXPRESS Language statement;

--- Mapping from XML schema language to EXPRESS language description;

--- EXPRESS description from a model exported XML mapping mode to another EXPRESS mode.
