Introduction
Information types and topics
Topics are the building blocks of modular documents, and organising topics by semantic information types is one of the architectural features of DITA.

Cross-referencing
Cross-references are a means of binding individual topics into a coherent and navigable document.
Content re-use
- Content re-use definition
  Content re-use is a means of improving efficiency by eliminating repetition of phrases, blocks of text, topics, and even collections of topics.
- Re-use and the DITA Maturity Model
  Content re-use is one of the features that you should adopt early in your move from style-based authoring to structured authoring with DITA.
- The content reference (conref) attribute
  The conref feature allows DITA content to be used in any number of different places in a collection. The conref attribute in a referencing topic specifies the source topic and the element within that topic to re-use.

- Organising re-use topics and elements
  - Managing re-use files
    There are two different approaches to managing DITA content re-use files, used to store conref referenced source elements. The preferred approach is to store the elements centrally in a dedicated re-use topic.
  - Organising elements within re-use topics
    You should use logical, identifiable id attributes. Short phrase-level elements intended for re-use can be organised into tables for ease of maintenance.
  - Finding elements to re-use
    Logically organising re-use elements into re-use files is one strategy to make re-use easier, but a DITA Content Management System will provide management features superior to files in a simple file system.
- Embedded topics and ditamaps
  The ditamap is a powerful tool for re-using topics in different output publications. Topics can also be re-used using ditabase topics, but you should avoid this technique.

DITA authoring concepts
Moving from style-based authoring to a structured authoring methodology such as DITA requires a radically different approach to writing.

Organising re-use topics and elements

Re-use of content is easier for the author to accomplish if the elements to be re-used are carefully organised in predictable locations.
