National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields o

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in ac

12、cordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International

16、 subclauses hereafter: 6.5.7 LogicalUnitLocator datatype 6.5.7.1 Introduction The locating of nested units is supported by defining an explicit structure to the LogicalUnitLocator that allows media locators to be included as sub-units. Furthermore, by supporting hierarchical structures directly thro

17、ugh this nesting, the LogicalUnitLocator retains a clear semantics when multiple locators are sequenced within a description to identify the union of logical units. 6.5.7.2 LogicalUnitLocator datatype syntax Syntax of the LogicalUnitLocatorType: ISO/IEC 15938-5:2003/Amd.2:2005(E) 2 ISO/IEC 2005 All

18、rights reserved6.5.7.3 LogicalUnitLocator datatype semantics Semantics of the LogicalUnitLocatorType: Name Definition LogicalUnitLocatorType Describes the location of logical unit of a media resource, such as a “track” of a CD or “chapter” of a DVD. The localization within a target resourcecan be sp

19、ecified using either LogicalUnit or ReferenceUnitelements. In the case that multiple instances of these elements are included within the description, the result is the union of the individual locator elements, e.g., chapter 1 and chapter 2 of a DVD. Nested logical units should be described using the

20、 SubUnit elements of each locator element. LogicalUnit Describes the localization of a logical unit by identifying the name of the logical unit, e.g., “chapter” and value, e.g., “2”. unit Identifies the unit, e.g., “chapter” using termReferenceType. The unit name can belong to a classification schem

21、e in order to enforce a controlled vocabulary. The termReferenceType also allows names to be used that do not belong to classification schemes when needed. value Describes the value of the unit, e.g., “2” using string. SubUnit Describes nested units located within the parent logical unit, e.g., “sec

22、tion 2” of “chapter 1”. SubUnit is of type MediaLocator to allow non-logical sub-units to be described. ReferenceUnit Describes the localization of a logical unit by identifying reference of the logical unit, such as by xpath expression. referenceGrp Identifies the reference of the logical unit usin

23、g xpath, idref, etc. 6.5.7.4 Example (informative) The following example describes the logical unit of a “chapter” of a DVD. This example assumes that a classification scheme “urn:dvd:logicalunit” has been defined for DVDs that identifies the names of its logical units, e.g., “chapter”. ISO/IEC 1593

24、8-5:2003/Amd.2:2005(E) ISO/IEC 2005 All rights reserved 3The following example describes the logical unit of a CD that corresponds to track 8 from disk 2. This example assumes that a classification scheme has been defined for CDs that identifies the names of its logical units. Furthermore, this exam

25、ple shows the explicit use of hierarchy of units to indicate that the track is from disk 2. The LogicalUnitLocator describes the increasing granularity and nesting of logical units in the case of hierarchical relationship using the SubUnit element. The following example uses the ReferenceUnit xpath

26、reference mechanism of LogicalUnitLocator to address a fragment of an XML resource. The following example uses the ReferenceUnit xpath reference mechanism of LogicalUnitLocator to address a fragment of an XML resource.
