A publishing system for efficiently creating dynamic Web content

This paper presents a publishing system for efficiently creating dynamic Web content. Complex Web pages are constructed from simpler fragments. Fragments may recursively embed other fragments. Relationships between Web pages and fragments are represented by object dependence graphs. We present algorithms for efficiently detecting and updating Web pages affected after one or more fragments change. We also present algorithms for publishing sets of Web pages consistently; different algorithms are used depending upon the consistency requirements. Our publishing system provides an easy method for Web site designers to specify and modify inclusion relationships among Web pages and fragments. Users can update content on multiple Web pages by modifying a template. The system then automatically updates an Web pages affected by the change. Our system accommodates both content that must be proof-read before publication and is typically from humans as well as content that has to be published immediately and is typically from automated feeds. Our system is deployed at several popular Web sites including the 2000 Olympic Games Web site. We discuss some of our experiences with real deployments of our system as well as its performance.
