Doug Wallace is the President of Agile, the makers of Thinking Cap®, a suite of XML-based e-Learning tools including Thinking Cap® Studio, an XML-based LCMS and Thinking Cap® Campus, an XMLbased, SCORM-Certified LMS.
E-Learning development since 1997 has mostly been an HTML-based process. However, this
works against easy re-use of content and single-source authoring for presentation in multiple
formats. The alternative is the XML-based production model, which has suffered from a lack of
familiar tools and from a lack of support from organizations in spite of its inherent advantages.
