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 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 organization, governmental and non-governmental, 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. 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.
International Standard ISO/IEC 13250 was prepared by Joint Technical Committee JTC1, Information technology.
Interactive documents combine data content with instructions that define the behavior of the interactive document; that is, how and when the content is represented on a computer display. Because a reader's interactions with a document might be important to its presentation, a standard way to encode behavior instructions associated with specific content is essential if the document is to be transportable. This standard focuses on the representation of the behavioral aspects of interactive documents and hyperdocuments. The language defined in this standard facilitates the interchange of interactive documents among heterogeneous development and delivery systems by defining the behavioral aspects of interactive documents independent of proprietary scripting or processing languages.
In the context of interactive documents, interactive means that a software application is responsible for dynamically rendering content in response to stimuli from users or other sources. The response is often to tailor the content and presentation of subsequent information. Therefore, to create an interactive document, developers must consider a philosophy different from that used to create documents and hyperdocuments that will be presented in a static manner; they must program behavior into the document. The inclusion of the behavior component is one facet of interactive documents that can cause incompatibility between interactive document development and delivery systems.
It is important to recognize the distinction between "document" in the SGML sense (a static source of data) and "document" in the rendition sense (a particular view or presentation of the source data). It is also important to recognize that any document can be made interactive in sense (1) through the application of behavioral style. Throughout this standard the term interactive document is used when referring to the presentation of the source data.
Standards currently exist for describing the structure, content, and static presentation of documents and hyperdocuments. The Interchange Standard for Multimedia Interactive Documents (ISMID) adds the missing component - a standard for representing the behavior of documents in an unambiguous way for the purpose of interchange among heterogeneous interactive document development and delivery systems. The behavior definition may be embedded within the documents to which it applies.
While there are established standards for implementing Graphical User Interface objects in a programming context, there is a need for a standard that will allow developers of interactive documents to express in a device independent manner how they intended to make use of those interface objects. ISMID provides an architecture for defining how the interface objects communicate with the structured content covered by existing standards.
Because the presentation of interface objects in interactive documents is often integral to the message being communicated, ISMID allows the developer to specify presentation properties of the interface objects. Types of presentation properties could include things such as font, color, and location of the object. It is up to the interactive document developer to decide whether ISMID is used to apply these properties or whether a style specification language like DSSSL is used.
This International Standard, known as the Interchange Standard for Multimedia Interactive Documents or ISMID, facilitates the interchange of Multimedia Interactive Documents (MIDs) among heterogeneous interactive document development and delivery systems by providing the architecture from which common interchange languages can be created. ISMID is a client architecture of International Standard ISO/IEC10744:1997, Information technology -- Hypermedia/Time-based Structuring Language (HyTime) and is an SGML application conforming to International Standard ISO 8879 -- Standard Generalized Markup Language.
ISMID also specifies use of the DSSSL expression language described in clause 8 of ISO/IEC 10179:1992 Information technology -- Processing languages -- Document Style Semantics and Specification Language (DSSSL).
In general, the rendering of a Multimedia Interactive Document (MID) requires three major components:
Various vendors, standards bodies, and other groups define the notations (such as SGML for text, CGM for graphics, MPEG for video, and WAV for audio) with which the information in the content component is represented. It is up to software vendors to determine the most effective way to implement the software component. Therefore, the ISMID standard addresses only the behavior component.
The ISMID standard defines an architecture that enables authors and developers to describe the behavior component of MIDs in a device-independent manner. This architecture is known as the ISMID architecture (clause 9). The ISMID architecture defines architectural forms for the behavior component.
The ISMID architecture includes:
Although interface objects are listed as a major part of the ISMID architecture, ISMID does not define architectural forms that represent these objects directly. Instead these objects are specified using architectural forms to describe the creation, modification, and destruction of the objects. The architectural forms for creation, modification, and destruction of objects are classified as responses because a MID would create, modify, or destroy an object only in response to a stimulus from a user or some other source.
The stimulus and response element forms in the architecture provide the templates for specific ISMID applications. These architectural forms within the architecture are general enough to allow for any new stimulus and response elements that may be required in the future.
It is important to note that content objects are not the actual information being conveyed to the user, but are used to render and manipulate the information. The information referenced by content objects can be reused, and can reside in various external notations that are independent of the content object.
An example ISMID application is included in this standard (non-normative annex B). The example defines a set of elements, derived from the architecture, for stimuli and responses. The semantics of the forms in the example reflect the objects, stimuli, and responses used in state-of-the-art interactive document development and delivery systems. For example, one of the element types defined in the example ISMID application is for displaying images. Because the image object is used to present information content to the user, the element is derived from the content object forms in the architecture.
The example elements implement all of the attributes of the architecture forms and add attributes that define the presentation properties of these objects as they exist in current use. For example, a button object in the example ISMID application has attributes that define properties for caption, visible, enabled, and foreground color.
It is envisioned that various industries and organizations will define ISMID applications in which they remove from and/or add to the specific objects, stimuli, and responses defined in the example application in order to meet the industry's requirements. These industry-defined applications shall also define the semantics of the objects, stimuli, and responses. Conforming ISMID applications must be defined according to the ISMID Application Definition Document (IADD) (Clause 10). The ISMID application in non-normative annex B is an example of an IADD.
The example application DTD in annex B includes notation forms for the most common information types in current use. These notation declarations do not imply that a conforming ISMID system must support these notations. The notations supported by an ISMID system shall be specified within the ISMID application. For example, the Department of Defense may specify that SGML must be supported for text while a commercial entity with existing software investments may prefer that RTF be supported for text. Which specific objects, stimuli, responses and notations must be supported for a particular industry or organization can be specified formally in the IADD.
The field of application of ISMID is Electronic Performance Support Systems (EPSS), computer-based interactive document systems that provide users access to just-in-time information and on-the-job training. Two common types of EPSS are Interactive Electronic Technical Manuals (IETMs) and Interactive Courseware (ICW).
The use of EPSSs is increasing within many industries as the quantity of information that workers must have access to increases. Because organizations are increasing their investments in these systems, it is important that they have a way to protect their investments by representing all aspects of the EPSS in a device independent manner.
Because ISMID is primarily a language that facilitates the interchange of interactive documents, it is not a conformance requirement that ISMID systems operate directly on the ISMID document in its native notation. Developers will probably chose to translate the ISMID representation to their own proprietary internal representation optimized for their application programs to execute.

behavior component
The instructions that govern how an interactive document responds to stimuli from various sources.
application
A DTD conforming to the ISMID architecture, and serving as the basis for a class of interactive documents e.g., for an industry.
container object
A type of interface object used to group other interface objects.
content object
A type of interface object used to render information content.
control object
A type of interface object through which interaction with an interactive document takes place.
document
As defined in ISO 8879:1986, a document is a collection of information that is identified as a unit and that is intended for human perception.
hyperdocument
As defined in ISO/IEC 10744:1997, a hyperdocument is two or more documents or other information objects that are connected to one another by one or more hyperlinks.
hyperlink
As defined in ISO/IEC 10744:1997, a hyperlink is an information structure that represents a relationship among two or more objects.
interface objects
Components of an interactive document that are the vehicle through which stimuli and responses occur.
interactive document
1. The presentation of a document in which the order, formatting, and content of the source information may be dynamically modified as the document is presented based on external stimuli (such as user interaction) and presentation algorithms defined within the document or within the software that governs the presentation of the document.
2. A source data collection that explicitly enables and defines the rules for its presentation as an interactive document.
NOTE 1. The source data for an interactive document need not explicitly enable or define its interactive behavior in order for it to be presented as an interactive document (in other words, all documents are potentially interactive whether or not they were originally authored with interactive presentation in mind). However, it is still useful to distinguish documents that explicitly enable and define interactive presentation from those that do not. In addition, through the use of location addressing it is possible to apply an explicitly interactive document to other documents in order to add explicit interaction definitions to them.
interactive document delivery system
The run-time software used to render an interactive document.
interactive document development system
A software system used to author interactive documents.
interactive presentation
A form of presentation of a document in which the order of navigation through the document content is modified during presentation in response to conditions.
NOTE 2. The modifications are typically in response to external stimuli, such as user interactions, which is why these presentations are termed "interactive". However, the dynamic modification can also be in response to presentation algorithms contained in the document or within the system controlling the presentation.
NOTE 3. A document need not be an interactive document in order for it to be the subject of an interactive presentation.
response
A reaction performed by the interactive document, triggered by a stimulus.
response chain
A predetermined sequence of responses that may be initiated by a single stimulus.
static document
NOTE 4. any static document in sense (2) can be presented as an interactive document given the necessary presentation software and behavioral definition. This behavioral definition may be provided by ISMID documents.
static presentation
A form of presentation of a document in which the order of navigation through the document content is essentially the same as the order in which the content appears in the computer representation of the document.
NOTE 5. In a static presentation, any dynamic modification is typically limited to the navigational functionality offered by a printed volume, such as page-turning and cross-reference following.
stimulus
An action, received by an interface object, that triggers reactions performed by the interactive document.
stimulus-driven
A system in which action is initiated when an interface object receives a stimulus.

A conforming ISMID system shall, at a minimum, support the HyTime Marker Function Language (HyFunk) expression language. This expression language is adequate for documents that require only integer arithmetic operations. HyFunk is based on the DSSSL expression Language. The following notation shall be used to specify use of HyFunk as the ISMID expression language.

A MID is defined as a stimulus-driven application. This means that interface objects within the MID wait for a stimulus initiated by a user, an external system, or another interface object before responding.
For each stimulus, the author/developer of a MID instance can define a series of responses that, at runtime, determine how the interface object will respond to the stimulus. Specific stimulus types are defined in the IADD for each ISMID application. Each stimulus in the ISMID application implements the attributes of the corresponding stimulus element form in the ISMID architecture, from which the element is derived. For each stimulus, the author may specify a series of specific actions (e.g., creating, destroying, or modifying objects and variables) that will occur in the MID. For example, when the user clicks a "Show Video" button (i.e., when the interface object labeled "Show Video" receives a click stimulus from the user), the developer could program the "Show Video" button to respond by:
Interface objects are the targets of user-, object- or externally-generated stimuli presented to the MID. The element type declaration for each element that creates or modifies an interface object can contain within its content model a series of stimulus elements. For example, a button control object could contain an "OnClick" stimulus and an "OnMouseOver" stimulus. Each stimulus element can contain a chain of one or more responses to be executed when the object receives the stimulus; this is referred to as "hard-coding" the response chain. Alternatively, the stimulus could reference a previously defined response chain; this is referred to as "soft-coding" the response chain.
Within a response chain, objects are created, modified, and destroyed. Control flow statements can also be included within response chains so that responses can be based on conditions or states within the MID.
Create object elements shall be used to create Container objects, Content objects, Control objects, and External objects.
<!entity % CreateObject "CreateContainer | CreateContentObject | CreateControl | CreateExternalObject">
Control flow shall allow construction of If, While, and Switch constructs.

Intrinsic data content is presented to the user through content objects. The information that is to be presented to the user is located through the use of HyTime location addressing. Location addressing shall be in accordance with the following types defined in International Standard ISO/IEC10744:1997, Information technology -- Hypermedia/Time-based Structuring Language (HyTime).

The Multimedia Interactive Document (MID) element form is the document element form of an ISMID document. When the MID is initiated, it receives an OnSystemStart stimulus. In response to this stimulus, the MID executes the Responses in the SystemChain. Zero or more other response chains can be defined within the MID element but they are not executed until they are referenced through a stimulus within the MID. These response chains exist as a pool of functions that can be called as required throughout the MID.
The ID attribute is a unique identifier for each element of this type. The outermost container objects parent attribute must exhibit the value of this attribute.

Interactive documents often set the value of an object property relative to another objects property values. A HyTime value reference attribute shall be used to obtain the effective value of an attribute from the properties of another object.
NOTE 6. The "effective value" of an attribute is the value that an application or architectural processor needs, which is not necessarily limited to the types of data or objects that can be expressed through SGML's attribute value syntax.
The value of the value reference attribute shall be fixed in the ISMID encompassing architecture (Document Type Definition).
A referential attribute value shall take precedence over any fixed attribute value defined in a document instance. If the effective value can not be resolved or if there is no referential attribute present, the value of the fixed attribute shall be used.
The referential attribute must refer to the ID of an Expression element that determines the effective value of the property attribute.
NOTE 7. For example, the position of a control element may be determined relative to the position of other control elements. In this case, the Expression element would contain a PropertyReference element that referred to a property of another object. The property, defined by the value of an attribute, would be resolved in the expression, and the results of the expression would be used as the effective value of the attribute. In this example, the value of the Left attriubute on the element with ID « ButtonX » is equal to the vlaue of the Left attribute on the element with ID « ButtonY » plus 100 pixels.

There are three classes of interface objects: containers; content objects; and controls. Within a MID, these objects exist in a hierarchy. This means that each object is contained within some larger parent object. The only exception to this rule is the outermost container object, the parent of which must be the MID element. Each object specifies its parent explicitly rather than relying on the SGML hierarchy to indicate parent-child relationships. This approach gives authors direct control of the order that objects are created and destroyed.
The create container (CreateContainer) element shall be used to create objects whose primary purpose is grouping other interface objects within the interactive document. Each container object may define stimuli to which the system will respond. If no stimuli are included for the container, the container cannot receive stimuli from users or other sources.
NOTE 8. Examples of container objects are windows, panels, and frames.
Variable declarations and stimuli are associated with the CreateContainer element through their occurrence within the CreateContainers content model.
The HyTime ireftype attribute contains the name of the Parent attribute followed by a list of GIs that express which create object element types are valid as parents of this object. The first item in the system chain shall be a container whose Parent is the GI for the element derived from the MID architectural form. The value of this attribute shall be fixed in the encompassing architecture (DTD).
A HyTime valueref attribute shall be used to obtain the effective value of an attribute from the properties of another object (clause 9.3). The value of the valueref attribute shall be fixed in the ISMID encompassing architecture (Document Type Definition).
The Parent attribute must reference element types derived from either the MID or the CreateContainer forms. The value of the Parent attribute for the outermost container object must be the value of the ID attribute of the element derived from the MID architectural form.
The ObjectNotExist attribute determines how the system shall handle the case where a referenced object is not found at runtime. The ObjectNotExist attribute applies to either a Parent container or an object used to provide the effective value for an attribute. The document author determines whether the "not found" condition should result in an error (that could be trapped or reported) or is ignored by the processing system. The default is to ignore the condition and continue processing.
NOTE 9. This attribute is provided to handle situations where interactive traversal leads to unexpected paths through the document, rather than to report logic errors. The error condition is most likely to occur when an object is either referenced before it is created or after it has been destroyed.
When an object expected to provide the effective value for an attribute does not exist and ObjectNotExist is set to « ignore, » the system shall use the fixed attribute value of required attributes. When a Parent container object does not exist, the content object shall not be created and ObjectNotExist shall determine whether the condition is reported or ignored.
The ID attribute is a unique identifier for each element of this type. Each object for which this object is the parent must exhibit the value of this attribute in its parent attribute.
The value of the Label attribute is a descriptive name for this object. This label may be used to identify the object to the user in the documentation or in the application.

The modify container (ModifyContainer) element shall be used to redefine properties of an existing container object, to modify values of variables that were declared for the container object, and/or to specify new or modify existing responses to stimuli for this container object.
The HyTime ireftype attribute contains the name of the Object attribute followed by a list of GIs that express which CreateContainer element types are valid objects to be modified. It may also contain the name of the Parent attribute followed by a list of GIs that express which CreateContainer element types are valid parent objects.
A HyTime valueref attribute shall be used to obtain the effective value of an attribute from the properties of another object (clause 9.3). The value of the valueref attribute shall be fixed in the ISMID encompassing architecture (Document Type Definition).
The Object attribute identifies the existing container object to be modified, by referring to its unique identifier. The Object attribute must reference element types derived from the CreateContainer form. The unique identifier (ID) shall not be modified, and the object label attribute (Label) shall not be modified. All other attributes of the object may be modified.
The Parent attribute may be optionally modified, but must continue to reference element types derived from either the MID or the CreateContainer forms.
NOTE 10. Modifying the Parent of a container object effectively moves all the contents of the container to the new Parent container.
The ObjectNotExist attribute determines how the system shall handle the case where a referenced object is not found at runtime. The ObjectNotExist attribute applies to a Parent container, an Object reference, or an object used to provide the effective value for an attribute. The document author determines whether the "not found" condition should result in an error (that could be trapped or reported) or is ignored by the processing system. The default is to ignore the condition and continue processing.
NOTE 11. This attribute is provided to handle situations where interactive traversal leads to unexpected paths through the document, rather than to report logic errors. The error condition is most likely to occur when an object is either referenced before it is created or after it has been destroyed.
When an object expected to provide the effective value for an attribute does not exist and ObjectNotExist is set to « ignore, » the system shall use the fixed attribute value of required attributes. When a Parent container object or an Object reference does not exist, the content object shall not be created and ObjectNotExist shall determine whether the condition is reported or ignored.
New variable assignments, and stimuli can be associated with the ModifyContainer element through their occurrence within the ModifyContainers content model. All variable declarations must occur when the object is created; new variables shall not be declared when modifying a container object.
All modifications of an object that use an expression to refer to a property attribute value refer to the current state of the object, not to the original creation state.

The create content object (CreateContentObject) element shall be used to create a host object for information content. If no stimuli are included for the content object, the content object cannot receive stimuli from users or other sources.
NOTE 12. Examples of content objects are text, image, video, audio, and animation objects.
The HyTime attribute ireftype associates names of referential attributes with element types to which their immediate targets must conform. This architectural declaration indicates that the SemanticContent attribute must reference a ContentReference element. In addition, the ireftype shall contain the name of the Parent attribute followed by a model group (contrained to be an "or group") that expresses which CreateContainer element types are valid as parents of this object. The value of this attribute shall be fixed in the encompassing architecture (DTD).
A HyTime valueref attribute shall be used to obtain the effective value of an attribute from the properties of another object (clause 9.3). The value of the valueref attribute shall be fixed in the ISMID encompassing architecture (Document Type Definition).
The Parent attribute must reference element types derived from the CreateContainer form. The document author is responsible for ensuring that the parent container is created before any content object that references it. The application developer is responsible for checking for existence of parent objects, and responding as specified in the ObjectNotExist attribute.
The ObjectNotExist attribute determines how the system shall handle the case where a referenced object is not found at runtime. The ObjectNotExist attribute applies to either a Parent container or an object used to provide the effective value for an attribute. The document author determines whether the "not found" condition should result in an error (that could be trapped or reported) or is ignored by the processing system. The default is to ignore the condition and continue processing.
NOTE 13. This attribute is provided to handle situations where interactive traversal leads to unexpected paths through the document, rather than to report logic errors. The error condition is most likely to occur when an object is either referenced before it is created or after it has been destroyed.
When an object expected to provide the effective value for an attribute does not exist and ObjectNotExist is set to « ignore, » the system shall use the fixed attribute value of required attributes. When a Parent container object does not exist, the content object shall not be created and ObjectNotExist shall determine whether the condition is reported or ignored.
The SemanticContent attribute is used to locate information that will be rendered in the content object. The content is located by reference through the HyTime nameloc element called ContentReference.
The ID attribute is a unique identifier for each element of this type. Any control object that will be a child of this content object must exhibit the value of this ID attribute in the childs Parent attribute.
The value of the Label attribute is a descriptive name for this object. This label may be used to identify the object to the user in the documentation or in the application.

The modify content object (ModifyContentObject) element shall be used to redefine properties of an existing content object, to modify values of variables that were declared for the content object, and/or to specify new or modify existing responses to stimuli for this content object.
The HyTime attribute ireftype associates names of referential attributes with element types to which their immediate targets must conform. This architectural declaration indicates that the SemanticContent attribute must reference a ContentReference element. The ireftype shall also contain the name of the Object attribute followed by a model group (contrained to be an "or group") that expresses which CreateContentObject element types are valid objects. It may also contain the name of the Parent attribute followed by a model group (contrained to be an "or group") that expresses which CreateContainer element types are valid parent objects.
A HyTime valueref attribute shall be used to obtain the effective value of an attribute from the properties of another object (clause 9.3). The value of the valueref attribute shall be fixed in the ISMID encompassing architecture (Document Type Definition).
The Object attribute identifies the existing content object to be modified, by referring to its unique identifier. The Object attribute must reference element types derived from the CreateContentObject form. The unique identifier (ID) shall not be modified, and the object label attribute (Label) shall not be modified. All other attributes of the object may be modified.
The Parent attribute may be optionally modified, but must continue to reference element types derived from the CreateContainer form.
NOTE 14. Modifying the Parent of a content object effectively moves the content a new Parent container. This could be used, for example, to support drag and drop functions.
The ObjectNotExist attribute determines how the system shall handle the case where a referenced object is not found at runtime. The ObjectNotExist attribute applies to either a Parent container or an object used to provide the effective value for an attribute. The document author determines whether the "not found" condition should result in an error (that could be trapped or reported) or is ignored by the processing system. The default is to ignore the condition and continue processing.
NOTE 15. This attribute is provided to handle situations where interactive traversal leads to unexpected paths through the document, rather than to report logic errors.

The Parent attribute must reference element types derived from the CreateContainer or CreateContentObject forms.
The ObjectNotExist attribute determines how the system shall handle the case where a referenced object is not found at runtime. The ObjectNotExist attribute applies to either a Parent container or an object used to provide the effective value for an attribute. The document author determines whether the "not found" condition should result in an error (that could be trapped or reported) or is ignored by the processing system. The default is to ignore the condition and continue processing.

The Caption property is a text string that appears in the TitleBar of a Window or as the text on a button. The Caption is optional. On a window, the caption shall appear only if the TitleBar property value="TitleBar"
The TitleBar property indicates whether a Window is to be rendered with a title bar. The title bar shall be used to move the Window .
The WindowState property allows the author to specify one of the following states for a Window object:
Normal- Object remains or is reset to a default or last displayed size
Maximized- Object is set to the maximum sized allowed by the client area of the display
Minimized- Object and its contents are reduced to an icon
The FontName property defines the name of a font or font family used in the object.
Numerical indicator of the font size, in points.
The font weight shall be defined as either Bbold or not bold (i.e., normal).
The Visible property indicates whether to show or hide a content object.
This property applies to the Image object only. The ActualWidth property contains a read-only value supplied by the system value that indicates the actual width in pixels of the image being displayed.
This property applies to the Image object only. The ActualHeight property contains a read-only value supplied by the system that indicates the actual height in pixels of the image being displayed.
The Left property sets the position of the object by placing its left edge at the horizontal dimension specified as the value of this property. The value is in pixels from the left edge of the parent container.
This property is used to reference an expression element for the purpose of setting the Left property for this object.
The Top property sets the position of the object by placing its top edge at the vertical dimension specified as the value of this property. The value is in pixels from the top edge of the parent container.
This property is used to reference an expression element for the purpose of setting the Top property for this object.
The Width property sets the width of the object to the indicated value, given in pixels.
This property is used to reference an expression element for the purpose of setting the Width property for this object.
The ViewHeight property sets the height of the object to the indicated value, given in pixels.
This property is used to reference an expression element for the purpose of setting the Height property for this object.
The Enabled property determines whether a control object is active or inactive.
The BevelWidth property sets the visual bevel at the edge of a button that makes it appear three dimensional.
The ForeColor property sets the color of captions. Colors are specified as #RRGGBB in hexadecimal.
This property is used to set a Video or Audio object to a Playing or Not Playing state. When the value is set to Playing, the video or audio clip in the content object will start to play. When the value is set to NPlaying, the video or audio clip in the content object will pause playing. Setting this property has no effect on the current location within the audio or video.
This propery specifies the frame number from which the video referenced by the video content object starts playing.
This property specifies the name of the entity containing the style sheet to be applied to the SGML doucment referenced by the SGML content object.
This property specifies the color with which the object will be filled.
This property specifies how the object will be rendered. If value is set to CopyPen, the object is rendered with the fill color solid. If the value is set to MaskPen the object is rendered with the fill color transparent.
