Carlos Evia teaches structured content authoring using DITA and similar tools at Virginia Tech.
Structured authoring offers a number of benefits, most notably easy content re-use. By carefully structuring content as it goes into a repository, it can be used later in a variety of publications and applications.
Structured authoring has its roots in the technical communications field. As other fields discover the benefits of structured content, interest in the practice has grown. This led Carlos and his colleagues on the DITA Technical Committee to develop a less-technical version of the DITA standard - Lightweight DITA - that can be used by marketers and other non-technical content creators.
