Tutorial drive pages are a medium for scripting the work flow and important logical options of a simulation sequence. The pages are informative as well as active. They convey knowledge captured from the simulation expert and they automatically initiate actions governed by automation functions that are referenced as tag attributes.
Drive pages are modular autonomous units containing their own logical sequences. Home drive pages can send control to sub-pages for common repetitive or special tasks. This de-centralized logic scheme follows the methodology of the Internet. Page-driven sequences can scale to any simulation complexity. By contrast, a centralized rules-based KBE or inference engine approach degrades in performance as rules are added. The rules based approach has proven not to scale for CAE.
Standard Generalized Markup Language, or SGML, as established by ISO Standard 8879:1986 is the “mother of all markup languages”. HTML is a particular implementation of the SGML standard. Recently, Extensible Markup Language, or XML, was introduced to enhance the usage of SGML. Essentially, XML is an SGML implementation employing HTML like tags. XML tags can be invented for various purposes, but they must follow the familiar HTML syntax rules.
Tutorial drive pages are written with certain defined XML tags to script a simulation work flow. The <HTML> sub elements within <dialog> tags provide packets of text and graphics information that are displayed to the user.
