Chapter Summary

  • A portal application is responsible for aggregating multiple sources of information content, customized for each user's needs and context.

  • If the content is in XML, then XSLT stylesheets can be used to filter, restructure, and present the same source customized for each user or device.

  • Content management includes definition of the XML vocabulary, creating content according to that vocabulary, and assigning additional metadata that facilitates searching and personalization.

  • Portal design includes specification of the portlets, content templates, and stylesheets required to present content within the portal.

  • A portal often allows each user to select and reposition portlets within the overall presentation format.

  • A portal is not necessarily displayed on a desktop PC, but the same general concepts apply when designing wireless applications using XML content.
