Presented at the Content Management Strategies/DITA North America conference in 2016; this version is from a repeat of the presentation in webinar form, and includes some additional slides. Lightweight DITA is being developed at OASIS by a subcommittee of the OASIS DITA Technical Committee. It is designed to make adoption of DITA easier for both users and tool developers. The subcommittee is looking at usage scenarios in areas such as marketing, education, software development, and machine industries. The goals of the (in-development) specification are: - simplified topic and map definitions with tighter content models and fewer elements - simplified specialization process that makes new specializations as easy to create as new topics - multi-format content, with mappings to not only XML, but also markdown, HTML5, and JSON Michael Priestley shares the current state of the lightweight DITA specification, focusing on the current draft document types for topic and map, and reviews the lightweight specialization process.
