From WebWisdomNT Curricula Database and Management System NPAC Tutorial on Tango/WebWisdomNT, Visit to ASC -- October 26 98, October 29 98. *
Full HTML Index
User accesses the HTTP server from HTML browser, providing in URL:
  • (1) locator of the servlet; (2) locator of a TDL template; (3) user data
The HTTP server passes call to servlet defined by (1).
Based on template locator (2), servlet reads template from an HTTP server
  • Servlet interprets contents of the template tag by tag, meanwhile contacting local database management system and other HTTP servers for data needed to complete the operation
  • The data is formatted according to the template and the parameters, and send back to user as a standard HTML file.

  • Second level cache used to store output cache (HTML-formatted output files). Cache system designed to support synchronous courseware delivery
Persistent tags
  • Object used for interpretation of a tag can (optionally) be re-used (no initialization of its internal data). Thus, one can use "interpretation history" of a tag.

Properties
  • Servlet behavior can be modified by the use of properties. There are configuration properties, predefined properties, user-defined properties (read form a file), system-defined properties, variable properties (defined by tags during template interpretation), and addressing properties.
