The product training manuals for complex machinery often consist of large-scale presentation-based documents with rich media. The content of the manuals is typically required to use up-to-date product information for effective training. Current training authoring tools have limitations in creating such large-scale product training course content in a timely manner due to the labor-intensive and time-consuming authoring processes. This paper presents an automated method to improve the process. It is based on formal specifications to dynamically generate DSSSL document styles for transforming the existing storage-based product documents into large-scale presentation-based product training manuals. The generated manuals are based on SCORM, an industry training course specification.
