Cocoon Sitemap ( Contd. )

• A sitemap is an XML file

• Sitemaps are hierarchical -- A sitemap can point, explicitly or implicitly, to sub-sitemaps

• A sitemap is translated into a java program and is compiled to bytecode

• Changes to sitemaps can be loaded dynamically and asynchronously.

• Cocoon community has debated extensively on philosophical aspects of Sitemap but nothing better has come out ( yet ! ).

Dynamic loading of sitemap ==> no need to stop and start the Cocoon servlet for changes in the sitemap to become effective.

Asynchronous loading of sitemap ==> The sitemap is read, validated, compiled and loaded in the background, without impacting the response time of the system during this process.

Sitemap Critique:

• Sitemap mixes control ( logic ) and management.

• Single point of failure.

• Hard to maintain.
