Abstract

S is a system for implementing data-intensive Web sites, which typically integrate information from multiple data sources and have complex structure. S's key idea is separating the management of a Web site's data, the specification of its content and structure, and the visual representation of its pages. S provides a declarative query language for specifying a site's content and structure, and a simple template language for specifying a site's HTML representation. This paper contains a comprehensive description of the S system and details the benefits of declarative site specification. We describe our experiences using S in a production application and describe three different, but complementary, systems that extend and improve upon S's original ideas.
