13、 for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work 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

14、the right to be represented on that committee. International organizations, governmental and non-governmental, 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. The pr

15、ocedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the edito

ISO 2013 All rights reserved v ISO 24531:2013(E) Introduction As the exchange of information via the interne

19、t and other wired and wire-free networks develops and expands, the use of XML (Extended Mark-up Language) and its variants continues to grow and develop. XML will be an important tool in the development and operation of “Intelligent Transport Systems” (ITS) services. However, within XML and its vari

20、ants there are options. In order to obtain maximum benefit, interoperability and re-use of data within the ITS sector, it is important to implement XML and its variants in a consistent manner. This International Standard provides definitions of how to use XML and its variants in a consistent and int

21、eroperable manner within the ITS sector.vi ISO 2013 All rights reserved INTERNATIONAL ST ANDARD ISO 24531:2013(E) Intelligent transport systems System architecture, taxonomy and terminology Using XML in ITS standards, data registries and data dictionaries 1 Scope This International Standard assists

22、ITS standards developers and users of ITS standards who wish to use XML, by providing a consistent definition of the rules and rule references for the use of XML within ITS systems. This International Standard defines consistent rules and rule references to provide a framework to be used when implem

23、enting XML-based applications in ITS, and particularly in specifying XML in ITS standards, ITS data registries and ITS data dictionaries. This International Standard also provides guidance and examples in respect of the use of XML in ITS, and the elaboration of XML within the ASN.1 data definitions

24、required by ISO 14813-6 and ISO 14817. NOTE A table of language comparisons (XML, ASN.1, UML) can be found in ISO 14813-6:2009. 2 Conformance This International Standard prescribes a conceptual model; it does not define any single physical implementation. It provides a consistent and interoperable m

25、eans of achieving interoperability for the international exchange of information in XML application programs. Regional and national XML schema have the option of providing additional schema and variants for use in local situations. In order to claim conformance with this International Standard, it i

26、s only required to design systems and exchange data consistently in accordance with the provisions of this International Standard. No external conformance procedures are proposed or defined in this International Standard, although regional, national and local implementations are free to, and may cho

27、ose to, define and require local conformance procedures. 3 Normative references The following referenced documents are indispensable for the application of this document.

33、terfaced to an XML parser, for example via DOM or SAX. 4.2 ASN.1 application application that uses ASN.1 encodings for communication (except XER) 4.3 ASN.1 schema definition of the content and structure of data using an ASN.1 type definition 4.4 association endendpoint of an association, which conne

34、cts the association to a classifier 4.5 attributeproperty of an element Note 1 to entry: It is additional information about a piece of data (element). Often attributes are used to pass information about the element and hence can be said to provide metadata for the element. An attribute is a value in

35、dicator (=) and the attribute value is specified within the tag (i.e. ). Attribute in XML is a name=”value” pair that can be placed in the start tag of an element. For XML, all values have to be quoted with single or double quotes. 4.6 attributefeature within a classifier that describes a range of v
