Recently, Google published the Google Sitemaps protocol that allows Web sites to inform Google about new content, like this blog entry.

I have done an implementation for OpenACS, which allows modules like lars-blogger to generate Google Sitemaps.

The infrastructure package can be found at

The code that generates the sitemap for lars-blogger is in

http://www.clasohm.com/prj/clasohm.com/browser/trunk/packages/lars-blogger/tcl/sitemap-procs.tcl
http://www.clasohm.com/prj/clasohm.com/browser/trunk/packages/lars-blogger/tcl/sitemap-init.tcl
http://www.clasohm.com/prj/clasohm.com/browser/trunk/packages/lars-blogger/www/index.vuh

For this to work, you will also need the directory "google-sitemaps" in the server root, which must be writable by the Web server.

The generated sitemaps can be downloaded at [ad_url]/google-sitemaps.xml. See

http://www.clasohm.com/google-sitemaps.xml

for an example.

If you want to retrieve a copy of the code, you can do so with Subversion and the URL http://www.clasohm.com/svn/clasohm.com/trunk/
