topicset

The <topicset> element defines a complete unit of content that can be reused in other DITA maps or other <topicset> elements. The <topicset> element can be especially useful for task composition in which larger tasks are composed of smaller tasks. The id attribute on a <topicset> is required, which ensures that the complete unit is available for reuse in other contexts.
A <topicset> is similar to a source file that contains nested topics, in that the combination of topics constitutes a complete self-contained unit. That unit of content can stand independently of the containing, prior, and following content within the original map context.

Example

This topic set represents a set of overview information about SQL. The information is reusable as a unit. 

<topicset id="sqlbasics" href="sqlOverview.dita">
  <topicref href="sqlSelection.dita"/>
  <topicref href="sqlJoin.dita"/>
  <topicref href="sqlFilter.dita"/>
  ...
</topicset>

Attributes

Name Description Data Type Default Value Required?
navtitle Specifies the title of the topic as it will appear in the navigation or tables of contents that are generated from the map. Beginning with DITA 1.2, the preferred way to specify the navigation title in a map is with the navtitle element, available inside the topicmeta element. CDATA #IMPLIED No
id This ID is the target for references by to the current set of information. The ID is required in order to ensure that a topicset is defined as a reusable unit of information. See ID attribute in the Architectural Specification for more details. ID #REQUIRED Yes
href A pointer to the resource represented by the <topicref>. See The href attribute for detailed information on supported values and processing implications. References to DITA content cannot be below the topic level: that is, you cannot reference individual elements inside a topic. References to content other than DITA topics should use the format attribute to identify the kind of resource being referenced. CDATA #IMPLIED No
keys Introduces one or more global identifiers for a resource referenced from a map. See The keys attribute for details on how to use the keys attribute. NMTOKEN #IMPLIED No
query This attribute is deprecated. It may be removed in the future. CDATA #IMPLIED No
copy-to Use the copy-to attribute on the <topicref> element to provide a different file name for a particular instance of the topic in the map (for example, to separate out the different versions of the topic, rather than combining them on output). The links and navigation associated with that instance will point to a copy of the topic with the file name you specified.

Use the <linktext> and <shortdesc> in the <topicref>'s <topicmeta> to provide a unique name and short description for the new copy.

CDATA #IMPLIED No
collection-type Collection types describe how links relate to each other. The processing default is "unordered", although no default is specified in the DTD or Schema.
unordered
Indicates that the order of the child topics is not significant.
sequence
Indicates that the order of the child topics is significant; output processors will typically link between them in order.
choice
Indicates that one of the children should be selected.
family
Represents a tight grouping in which each of the referenced topics not only relates to the current topic but also relate to each other.
-dita-use-​conref-​target
See Using the -dita-use-conref-target value for more information.

Usage of the collection-type attribute on <reltable> and <relcolspec> is currently undefined and reserved for future use.

(unordered | sequence | choice | family | -dita-use-​conref-​target) #IMPLIED No
processing-role Describes the processing role of the referenced topic. The processing default is "normal". If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor.
normal
Normal topic that is a readable part of the information.
resource-only
The topic is used as a resource for processing purposes, but is not a readable unit of information on its own. This topic should not be included in a rendered table of contents, and the topic should not be rendered on its own.
-dita-use-​conref-​target
See Using the -dita-use-conref-target value for more information.
(normal | resource-only | -dita-use-​conref-​target) #IMPLIED No
type Describes the target of a reference. See The type attribute for detailed information on supported values and processing implications. CDATA #IMPLIED No
scope The scope attribute identifies the closeness of the relationship between the current document and the target resource. See The scope attribute for more information on values. (local | peer | external | -dita-use-​conref-​target) #IMPLIED No
locktitle If locktitle is set to "yes", the <navtitle> element or @navtitle attribute is used if it is present. Otherwise, the navtitle is ignored and the navigation title is retrieved from the referenced file.

Note

The @navtitle attribute is deprecated in favor of the <navtitle> element. When both a <navtitle> element and a navtitle attribute are specified, the <navtitle> element should be used.
yes
The navtitle in the map is used.
no
The navtitle or title of the topic is used. This is the processing default.
-dita-use-​conref-​target
See Using the -dita-use-conref-target value for more information.
(yes | no | -dita-use-​conref-​target) #IMPLIED No
format The format attribute identifies the format of the resource being referenced. See The format attribute for details on supported values. CDATA #IMPLIED No
linking Defines some specific linking characteristics of a topic's current location in the map. If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor.
targetonly
A topic can only be linked to and cannot link to other topics.
sourceonly
A topic cannot be linked to but can link to other topics.
normal
A topic can be linked to and can link to other topics. Use this to override the linking value of a parent topic.
none
A topic cannot be linked to or link to other topics.
-dita-use-​conref-​target
See Using the -dita-use-conref-target value for more information.
(targetonly | sourceonly | normal | none | -dita-use-​conref-​target) #IMPLIED No
toc Specifies whether a topic appears in the table of contents (TOC). If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. (yes | no | -dita-use-​conref-​target) #IMPLIED No
print Specifies whether the topic should be included in a print-specific rendition, such as PDF. The processing default is "yes". If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor.
yes
Include the topic in the print-oriented file.
no
Do not include the topic in a print-oriented file.
printonly
Only include the topic when rendering the DITA content in a print-oriented context; the topic should not be included in other contexts, such as when rendering as HTML.
-dita-use-​conref-​target
See Using the -dita-use-conref-target value for more information.
(yes | no | printonly | -dita-use-​conref-​target) #IMPLIED No
search Describes whether the target is available for searching. If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor.
yes
no
-dita-use-​conref-​target
(yes | no | -dita-use-​conref-​target) #IMPLIED No
chunk A topicset defines a group of information that will generally be used as a single navigable unit. The chunk attribute defaults to to-navigation to indicate that this is a distinct unit of information.

For a detailed description of the chunk attribute and its usage see the section on Chunking in the DITA Architectural Specification.

CDATA to-navigation No
conref-atts attribute group (conref, conrefend, conaction, conkeyref) A set of related attributes; includes all of the attributes described in id-atts attribute group except for the id attribute.
select-atts attribute group (props, base, platform, product, audience, otherprops, importance, rev, status) A set of related attributes, described in select-atts attribute group
localization-atts attribute group (translate, xml:lang, dir) A set of related attributes, described in localization-atts attribute group.
global-atts attribute group (xtrf, xtrc) A set of related attributes, described in global-atts attribute group
class, outputclass, keyref Keyref provides a redirectable reference based on a key defined within a map. See The keyref attribute for information on using this attribute. Class and outputclass are described in Other common DITA attributes
