13、ord ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical c

14、ommittees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in t

15、he work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare Internation

16、al Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the

19、C 12785-2:2011(E) ISO/IEC 2011 All rights reserved v Introduction This part of ISO/IEC 12785 will be used as the basis for the production of the following documents: ISO/IEC 12785-3 (Best practice and implementation guide); Content Packaging XML XSD. 1)This part of ISO/IEC 12785 details how the ISO/

20、IEC 12785-1 information model should be represented using XML schema. The content packaging binding is contained in two XML schemas and two vocabulary files. The vocabulary files are instances of the IMS Vocabulary Definition Exchange specification. ISO/IEC 12785-3 provides non-normative guidance on

21、 how to use the binding and information model. For a conceptual overview of ISO/IEC 12785, see ISO/IEC 12785-1. For a discussion of potential applications, see ISO/IEC 12785-3. Conformance to ISO/IEC 12785 is addressed within ISO/IEC 12785-1. 1) This XML schema definition can be accessed from: http:

25、ms and definitions apply. 3.1 binding XML data binding means of representing the information in an XML document NOTE See XML data binding of Wikipedia: http:/en.wikipedia.org/wiki/XML_data_binding (retrieved November 18, 2009). 3.2 control file single computer file that governs the binding of the Co

26、ntent Packaging Information Model to make it suitable for machine processing NOTE A software component can refer to a control file when assessing the validity of a bound instance of the information model or to guide the creation of a bound instance of the information model. EXAMPLE A file containing

27、 an XML schema can be used as a control file for an XML binding of a manifest. BS ISO/IEC 12785-2:2011ISO/IEC 12785-2:2011(E) 2 ISO/IEC 2011 All rights reserved 3.3 content individual file or multiple files usable in learning, education and training NOTE 1 A logical unit of usable (and reusable) inf

28、ormation can be described by a logical package. NOTE 2 logical package can contain one or more units of content. 3.4 logical package representation of one or more units of usable (and reusable) content NOTE A logical package encompasses the full set of components described by the manifest and its ch

29、ild manifests, including the local components and the remote components included by reference.

30、6 manifest description of files and any logical relationships between them, contained or referenced in a content package 3.7 metadata content packaging descriptive information about logical packages, logical organizations, content and files NOTE 1 Metadata can be assigned to any of the core structur

31、es within the logical package, including the manifest. NOTE 2 Any binding of a metadata object is permitted. Each object of metadata can be local or remote. ISO/IEC 12785-1:2009 3.8 organization logical relationships, such as a hierarchical tree, among unit of content NOTE More than one logical orga

32、nization can be described in a manifest. 3.9 package unit of usable (and reusable) content NOTE 1 This can be part of a learning course that has instructional relevance outside of a content aggregation and can be delivered independently, as an entire learning course or as a collection of learning co

33、urses. NOTE 2 A package is able to stand-alone; that is, it contains all the information needed to use the contents for learning, education, and training when it has been unpacked. 3.10 resource content packaging one URL entry point and zero or more references to files that are required before the c

34、ontent is launched NOTE The files described by a resource can be local or remote.

In accordance with the IMS Global Learning Consortium (GLC) Namespace Policy IMS-NAMESPACE specified in IMS Content Packaging XML Binding, the “name” of an element is appended to a IMS GLC namespace URI to con

41、struct a Uniform Resource Identifier as a globally unique identifier for that element. The use of element names and URIs in the context of different implementation technologies is explained in ISO/IEC 12785-2.
