Learning and training specializations

In this section:

1. Overview
   The DITA learning and training specializations address several important requirements facing developers and consumers of instructional content.
2. Objectives of the DITA learning and training specializations
   The DITA learning and training specializations build on best practices for modular content design, following DITA principles.
3. A learning objects approach to learning and training content
   The DITA learning and training specializations apply DITA principles and best practices for using topic-based and modular content to plan, develop, and deliver learning and training content.
4. Use cases
   Several use cases inform the design and development of the DITA learning and training specializations.
5. Summary of learning topic, map, and domain designs
   The DITA learning and training specializations provide a set of specialized DITA topics, a learning interactions domain, a learning metadata domain, and a learning map domain to support creating and delivering structured learning content.
6. Support for learningDomain1 and learningDomain2
   Many questions require multiple block elements for the question statement ("prompt" or "stimulus" in instructional design parlance) and for feedback. The DITA 1.2 interaction design, learningDomain (and referred to informally as "learning 1"), only allows for a single paragraph question and single-paragraph feedback. The learningDomain2 design allows block elements with question statements, answer content, and feedback.
7. Learning and training specialization usage
   The DITA 1.3 learning and training support includes new domains that deprecate the DITA 1.2 interactions but provide a path for backward compatibility.
