The committee responsible for this document is ISO/TC JTC 1, Information technology, Subcommittee SC 35, User interfaces. This second edition

18、cancels and replaces the first edition (ISO/IEC 247525:2008), which has been technically revised. 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 4

19、 Target description Part 5: Resource description Part 6: Web service integration ISO/IEC 2014 All rights reserved v ISO/IEC 24752-5:2014(E) Introduction This is the second edition of this part of the International Standard. The main purpose of the revision is an alignment with recent developments i

20、n the Web service area, in particular with the new ISO/IEC 24752- 6 on Web service integration, along with an overall simplification of the specified technologies. This part of ISO/IEC 24752 defines a format for describing atomic resources, resource sheets, grouping resources, and grouping sheets re

21、levant to the user interface of a device or service (“target”). For atomic resources that are stored in a resource sheet, a storage format is specified. For atomic resources that are stored externally to the resource sheet, the pertinent format type specification applies. A resource is any object th

22、at is used as an entity or to support decision making in the construction of a concrete user interface. This part of ISO/IEC 24752 specifies how resources are described in the context of the universal remote console (URC) framework. It defines a format for describing atomic resources, resource sheet

23、s, grouping resources, and grouping sheets relevant to the user interface of a device or service (“target”). Atomic resources include text and non-text elements of a user interface such as labels, help text, keyboard shortcuts (access keys), associated words (keywords) and location text. Non-text el

24、ements may include icons, sounds or videos. Atomic resources can be characterized as follows. An atomic resource is of static nature, i.e. it does not change during the users interaction with the target. NOTE 1 This is not meant to exclude atomic resources that contain references (placeholders) to v

25、alues of socket variables. In this case the atomic resource itself (i.e. the static text with the reference to the socket variable) doesnt change, but its rendition may change when the targets state changes. An atomic resource can be of any form, including textual, visual, auditory, and multimodal.

26、This is reflected in the atomic resources type. Atomic resource types include text, sound, image, animation, and video clip. In this context animations and video clips are construed as static objects because they dont change over the user interfaces lifetime (the recorded bits of the video clip dont

27、 change when it is played). An atomic resource of type “Text” is modality-independent, i.e. it can be rendered in visual, auditory, or tactile forms. Atomic resources of types other than “Text” are modality-specific. An atomic resource is typically specific to the cultural, language, and functional

28、accommodation of a user. For example, textual atomic resources are typically language specific; images can be culture- specific; picture symbols can be used to represent concepts that can be understood by people with certain cognitive disabilities. An atomic resource can be replaced by a (supplement

29、al) resource (which is itself an atomic resource). Examples of atomic resources are the following: a text string used to label a window; a text string containing help for an interface element; an icon used to label a button; a Bliss symbol labelling a function; a sound file that announces help instr

30、uctions; a text string that describes how to locate an ATM in a public building. An atomic resource description specifies characteristics (as properties) of an atomic resource. Properties include its type, its use context, and the atomic resources storage location and format. The use context specifi

31、es the usage location (specific element in a specific user interface), usage role (e.g. label or help text), and language context pertaining to the application of an atomic resource.vi ISO/IEC 2014 All rights reserved ISO/IEC 24752-5:2014(E) An atomic resource can have more than one atomic resource

32、description, specifying additional properties and alternative property values, and several sets of use contexts. Also, atomic resource descriptions and the atomic resource they describe dont have to be stored in one file or on one server necessarily. For example, some atomic resources (e.g. images)

33、can be stored as binary files, and their descriptions are stored in text files. A grouping resource (or short grouping) specifies a hierarchical grouping of user interface elements that is external to a socket description. This part of ISO/IEC 24752 applies groupings to user interface socket element

34、s, but that is not a restriction in general. Groups of user interface (UI) elements can be nested, and subgroups and UI elements can occur multiple times within different groups. Groupings are structural hints as to how to present a concrete user interface made up of individual user interface elemen

35、ts, including user interface characteristics such as layout and navigation. Supplemental resources can replace or supplement the target resources. By choosing between a set of alternative objects when constructing the concrete user interface, the result can be tailored towards user preferences and u

36、ser device capabilities. The mechanism of supplemental resources facilitates the generation of specialized user interfaces that build on a common (modality-independent) user interface model, the user interface socket provided by the manufacturer of a target. A resource sheet is a file that contains

37、atomic resource descriptions of related atomic resources, plus optionally the atomic resources themselves (if they are textual). Alternatively (and for binary atomic resources) the atomic resources can be stored in individual files separate from the resource sheet. Typically, a manufacturer would pr

38、ovide one resource sheet per target and language. Third parties can provide additional resource sheets pertaining to the same target. See Annex A for a sample resource sheet. A grouping sheet is a file that contains groupings. Typically, a manufacturer would provide one grouping sheet per target in

39、a language-independent manner. Third parties can provide additional grouping sheets pertaining to the same target. See Annex A for a sample grouping sheet. One purpose of this part of ISO/IEC 24752 is to facilitate the development and deployment of a wide variety of devices (from different manufactu

40、rers) that can act as URCs. The URC framework and its components are specified in part 1, and the user interface socket in part 2 of this International Standard. A user interface socket is a machine-interpretable description of the state and functions of the target or a part of the target. The targe

41、t description is specified in ISO/IEC 24752-4. Within the URC framework, an atomic resource makes reference to a specific element in a user interface socket (described in a user interface socket description), to a specific element in a target description, or to any form of user interface implementat

42、ion description. NOTE 2 Within the URC framework, there needs to be a common set of resource types and a common format for resource descriptions so that they can be used by any URC. This part of ISO/IEC 24752 defines both. In this part of ISO/IEC 24752, the terms “resources” and “resource descriptio

43、ns” include only those objects and descriptions that conform to the International Standard formats defined in this part of ISO/IEC 24752. It is important to note that URCs can employ other types of resources and resource descriptions beyond those described in this part of ISO/IEC 24752. ISO/IEC 2014

44、 All rights reserved vii Information technology User interfaces Universal remote console Part 5: Resource description 1 Scope ISO/IEC 24752 is a multi-part International Standard that aims to facilitate operation of information and electronic products through remote and alternative interfaces and in

45、telligent agents. This part of ISO/IEC 24752 defines syntax and semantics for describing atomic resources, resource sheets, groupings, and grouping sheets relevant to the user interface of a device or service (“target”). 2 Conformance An extensible markup language (XML) fragment is an atomic resourc

46、e description in conformance with this part of ISO/IEC 24752 if it conforms to Clause 6. An atomic resource description may use language extensions if the extensions are coded in XML syntax, and if it follows the syntax and requirements outlined in this part of ISO/IEC 24752 for all of its non-exten

47、sion parts. An XML file is a resource sheet in conformance with this part of ISO/IEC 24752 if it conforms to Clause 7. A resource sheet may use language extensions if the extensions are coded in XML syntax, and if it follows the syntax and requirements outlined in this part of ISO/IEC 24752 for all

48、of its non-extension parts. An XML fragment is a grouping resource in conformance with this part of ISO/IEC 24752 if it conforms to Clause 8. A grouping resource may use language extensions if the extensions are coded in XML syntax, and if it follows the syntax and requirements outlined in this part

49、 of ISO/IEC 24752 for all of its non- extension parts. An XML file is a grouping sheet in conformance with this part of ISO/IEC 24752 if it conforms to Clause 9. A grouping sheet may use language extensions if the extensions are coded in XML syntax, and if it follows the syntax and requirements outlined in this part of ISO/IEC 24752 for all of its non-extension parts.
