11、:2008(E) iv ISO/IEC 2008 All rights reservedForeword 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 developme
12、nt 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 of mutual interest. Other international organizations, governmental and non-governmental,
13、 in liaison with ISO and IEC, also take part in the 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 jo
14、int 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 Standard requires approval by at least 75 % of the national bodies casting a vote. Atten
15、tion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24752-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, S
16、ubcommittee SC 35, User interfaces. ISO/IEC 24752 consists of the following parts, under the general title Information technology User interfaces Universal remote console: Part 1: Framework Part 2: User interface socket description Part 3: Presentation template Part 4: Target description Part 5: Res
17、ource description ISO/IEC 24752-3:2008(E) ISO/IEC 2008 All rights reserved vIntroduction A presentation template (PreT) in the presentation template markup language is a user-oriented representation of a target described in a user interface socket specification. It maps user interface socket element
18、s to interaction (presentation and user input) mechanisms. It provides a structure into which elements of the presentation are embedded. The presentation elements themselves are modality-independent, i.e. capable of adaptation to any delivery context. The main content of a presentation template is a
19、 structured set of abstract interactors. These are user interface elements that describe a choice for the user to make, some input to obtain from the user, or some output to convey to the user. Each interactor is bound to a single socket element. NOTE The PreT markup language is similar to the XForm
20、s form controls. However, significant differences exist. Firstly, PreT markup language does not include the specification of natural language atomic resources such as labels and help texts. These atomic resources are defined externally. Secondly, PreT interactors bind to user interface socket elemen
21、ts, and XForms form controls bind to elements in an XForms data model. As a brief introduction to the presentation template concept, a short example is presented, showing a complete presentation template for a digital thermometer whose user interface socket is included in Annex B. The thermometer is
22、 always on, as it is connected to the mains. It displays the current temperature, maximum and minimum temperatures, and can do this in Fahrenheit or centigrade. It includes a command for resetting the maximum and minimum temperatures. It requires the user to provide confirmation of a reset operation
23、. EXAMPLE http:/myurc.org/iso24752-3/2007 Each of the constants, variables, commands and notify elements within the socket is represented by an interactor within the presentation template, and a grouping structure is provided, grouping the temperature readings together. The structure also provides a
24、 default order for presentation of the elements (the order of appearance within the description) and indicates which elements are relevant when the user is being asked to confirm a reset command (notify state “checkReset” is active). NOTE Resources such as labels, help texts and keywords pertaining
25、to elements of a presentation template are not included within the presentation template itself but provided separately. Resources reference presentation template elements using the presentation templates name (URI) and the element ids. Refer to ISO/IEC 24752-5 for further details. INTERNATIONAL STA
26、NDARD ISO/IEC 24752-3:2008(E) ISO 2008 All rights reserved 1Information technology User interfaces Universal remote console Part 3: Presentation template 1 Scope ISO/IEC 24752 is a multi-part International Standard to facilitate operation of information and electronic products through remote and alt
27、ernative interfaces and intelligent agents. This part of ISO/IEC 24752 defines a language (presentation template markup language) for describing modality-independent user interface specifications, or presentation templates, associated with a user interface socket description as defined by ISO/IEC 24
28、752-2. The purpose of a presentation template is to provide the URC with hints as to how to build a usable and consistent user interface for a target device or service that is described in a user interface socket description as referenced above. The hints are of an abstract nature, and are intended
29、to apply to any delivery context. These hints primarily provide information on structuring, grouping and linearization of the socket elements. Elements within a presentation template can be referenced by atomic resources whose format is given by ISO/IEC 24752-5. Taken together, a presentation templa
30、te, socket description, and appropriate atomic resources can be used to construct a user interface in any modality (e.g. visual, auditory, tactile, multimodal), through which a user can access and control a target. 2 Conformance An extensible markup language (XML) file is a presentation template in
31、conformance with this part of ISO/IEC 24752 if it has the MIME type specified in 5.2, if applicable, and its root element is the element as defined in Clause 6. An XML file does not conform to this part of ISO/IEC 24752 if it uses any element, attribute or value that is not part of this specificatio
32、n. NOTE 1 Target manufacturers who want to add information to a presentation template beyond the elements, attributes and values specified in this part of ISO/IEC 24752 can do so by externally providing (proprietary) resource descriptions that point into the structure of a presentation template. Ref
33、er to ISO/IEC 24752-5 for details. NOTE 2 Future versions of this part of ISO/IEC 24752 might add new elements, attributes and values. They might also drop the policy of strict language conformance in favor of allowing for language extensions. Therefore, URC manufacturers are encouraged to implement
34、 their URCs so that unrecognized markup is ignored without failing.

42、standards 5.1 Relation to XML This specification defines an XML based language. Markup in XML is case sensitive. Tags and attributes are not localizable, i.e. their names and values are identical for all international languages. As with all XML based languages, white space characters immediately sur
43、rounding tags are non-significant. This specification makes use of the namespaces concept defined in http:/www.w3.org/TR/REC-xml-names/ to enable the import of element and attribute names defined elsewhere. All element and attribute names used in this document with no namespace prefix are defined by
44、 this International Standard and are part of the namespace http:/myurc.org/ns/pret. If not used as default namespace, the namespace identifier pret should be used for it. This specification makes use of the following namespaces, and uses the naming convention namespace:prefix (e.g. xsd:schema) when
45、referring to constructs from foreign namespaces. xmlns:xsd=“http:/www.w3.org/2001/XMLSchema“: XML schema definition is used to describe type information for resources. This specification requires version 1.0 of the W3C XML Schema definition as identified by the URI shown. dc: The Dublin Core Metadat
46、a Element Set V1.1 namespace (http:/purl.org/dc/elements/1.1/), as specified in ISO 15836:2003 dcterms: The DCMI Metadata Terms namespace (http:/purl.org/dc/terms). Other namespaces may be included as required. For an XML Schema definition for the PreT markup language see Annex A. 5.2 MIME type A pr
47、esentation template shall have a MIME type of “application/urc-pret+xml”, if applicable (as specified in IETF RFC 2046). 6 Structure of a presentation template 6.1 General A presentation template is modality-independent, and can be thought of as a set of hints for rendering a socket. Elements in the
48、 description are mapped to elements in a user interface socket. A presentation template is defined as an XML document with the following structure. A presentation template document shall be coded in UCS according to ISO/IEC 10646. EXAMPLE ISO/IEC 24752-3:2008(E) 4 ISO 2008 All rights reservedNOTE Wh
