- Element quick reference
  This section contains a listing of DITA elements.
- Topic elements
  The base topic elements include elements that make up the core building blocks of the DITA topic, such as topic, body, and related-links, as well as elements like <p> and <ph> that are used in many topic specializations. Some of these elements are also available inside the <topicmeta> map element.
- Map elements
  Map elements include the core components of DITA maps, such as <topicref> and <reltable>, as well as general purpose map specializations in the map group domain.
- Metadata elements
  Metadata elements include information that is located within the <topicmeta> element (in maps) or <prolog> element (in topics), as well as indexing elements that can be placed in additional locations within topic content.
- Domain elements
  General purpose domains are not specific to any type of information, such as the hazard statement domain that provides elements for describing hazardous situations.
- Classification elements
  Classification elements support managing metadata. Those in the subject scheme map are used to define controlled values and to bind the controlled values to DITA attributes as enumerations. Those declared in the classification domain are used in other maps to classify content according to the scheme.
- Specialization elements
  Several DITA elements exist either for architectural reasons or for support of specialized markup yet to be designed. Although there is little need to use these elements unless you are directed to, some of them, such as <state>, can be used if your content makes use of these semantic distinctions. For example, a discussion of signals on a gate of an integrated logic circuit might use the <state> element to represent either on or off conditions of that gate.
- Legacy conversion elements
  Conversion elements exist primarily to aid in the conversion of content to DITA.
- DITAVAL elements
  A conditional processing profile (DITAVAL file) is used to identify which values are to be used for conditional processing during a particular output, build, or some other purpose. The profile should have an extension of .ditaval.
- Technical content elements
  Elements in the technical content section include the original Concept, Task, and Reference specializations, as well as specializations added in later releases. It also includes domains designed primarily for technical content.
  - Concept elements
    DITA concept topics answer "What is..." questions. Use the concept topic to introduce the background or overview information for tasks or reference topics. The concept topic restricts content following a section or example to other sections or examples. For more details on when to use concept and other information types, please refer to the DITA architectural specification.
  - Task elements
    Task topics answer "How do I?" questions, and have a well-defined structure that describes how to complete a procedure to accomplish a specific goal. Use the task topic to describe the steps of a particular task, or to provide an overview of a higher-level task. The task topic includes sections for describing the context, prerequisites, actual steps, expected results, example, and expected next steps for a task. For more details on when to use task and other information types, please refer to the DITA architectural specification.
  - Reference elements
    Reference topics describe factual material about a subject, such as the commands in a programming language. This format is also suitable for bibliographies, catalogues, the list of ingredients for recipes, and similar collections of structured descriptive prose. For more details on when to use reference and other information types, please refer to the DITA architectural specification.
  - Troubleshooting elements
    Troubleshooting topics document corrective action such as troubleshooting or alarm clearing.
  - Glossary elements
    Glossary elements include those elements designed to specify terms and their definitions, as well as elements that are designed to group, reference, or otherwise make use of information in the glossentry topic.
  - Bookmap elements
    Elements in the bookmap section are used to organize DITA content into book form. They include elements for dividing up content, such as chapter and appendix, as well as metadata specific to publishing.
    - Bookmap content elements
      The Bookmap specialization of ditamap supports standard book production for collections of DITA topics.
      - <bookmap>
        The <bookmap> element is a map specialization used to describe the relationships among a set of DITA topics intended to be configured as a traditional book. Bookmaps consist of references to topics organized as book content. The topic references therefore are labeled according to the book components they point to, such as book title, front matter, chapter, and appendix.
      - <abbrevlist>
        The <abbrevlist> element references a list of abbreviations. It indicates to the processing software that the author wants an abbreviation list generated at the particular location.
      - <amendments>
        The <amendments> element references a list of amendments or updates to the book. It indicates to the processing software that the author wants an amendments list generated at the particular location.
      - <appendices>
        The <appendices> element is an optional wrapper for <appendix> elements within a bookmap.
      - <appendix>
        The <appendix> element references a topic as a appendix within a book.
      - <backmatter>
        The <backmatter> element contains the material that follows the main body of a document and any appendices. It might include items such as a colophon, legal notices, and various types of book lists such as a glossary or an index.
      - <bibliolist>
        The <bibliolist> element references a topic containing a list of bibliographic entries within the book. It indicates to the processing software that the author wants a bibliography, containing links to related books, articles, published papers, or other types of material, generated at the particular location. If no @href attribute is specified on the <bibliolist> element, an external processor might generate a list of bibliographic entries at this location.
      - <bookabstract>
        The <bookabstract> element references a topic used within a bookmap as a brief summary of book content, generally output as part of the book's front matter. It is used to help the reader quickly evaluate the book's purpose.
      - <booklibrary>
        The <booklibrary> element contains the library information for a book. Library entries contain information about the series, library, or collection of documents to which the book belongs.
      - <booklist>
        The <booklist> element is a general purpose element, designed for use in specializations, that references a topic or map containing a list of items within the book. For example, it could be used to reference a topic that contains a list of authors for the book. When a more specific element is already available, such as <tablelist> for a list of tables, use that element instead.
      - <booklists>
        The <booklists> element references lists of various kinds within the book. For example, it can be used within <frontmatter> to reference a <toc>, <tablelist>, and <figurelist>, or within <backmatter> to reference a <glossarylist>, <indexlist>, and <abbrevlist>. It indicates to the processing software that the author wants the lists generated at the <booklists> location.
      - <booktitle>
        The <booktitle> element contains the title information for a book, including the library title, main title, subtitle, and other titles (as required).
      - <booktitlealt>

      - <chapter>
        The <chapter> element references a topic or map as a chapter within a book.
      - <colophon>
        The <colophon> element references a topic describing how this document was created. In publishing, a colophon describes details of the production of a book. This information generally includes the typefaces used, and often the names of their designers; the paper, ink and details of the binding materials and methods might also receive mention. In the case of technical books, a colophon might specify the software used to prepare the text and diagrams for publication. The <colophon> can appear in the <frontmatter> or <backmatter>.
