(via) Interesting developments on the web front over the last week what with Java being opensourced and now the web’s big three (Google, Microsoft and Yahoo) agreeing to a standard sitemap protocol for developers. At a basic level, a sitemap is a top-down view of the link structure of your site with a sitemap itself being an XML file used to describe each of those links in turn, sitemaps making things a lot easier for search engines and web users to find content (and up to date content) on your website.
Interesting to see what else lies on the collaborative front between these three.
