Offener Metadaten-Standard von Google, Microsoft und Yahoo für intelligentere Webcrawler

Heute ist ein guter Tag für alle, die Informationen im Web anbieten oder suchen. Battelle’s Searchblog meldet: Search Engines Unite On Unified Sitemaps System. Aus dem Beitrag:

In alphabetical order, Google, Microsoft and Yahoo have agreed to all support a unified system of submitting web pages through feeds to their crawlers. Called Sitemaps, (…) all three search engines will now support the method. (…) Other search engines are also invited to use the system — it has specifically been placed as open property through Creative Commons so that others can make use of it.

Die Website der Initiative, sitemaps.org faÃ?t zusammen, worum es geht:

Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is an XML file that lists URLs for a site along with additional metadata about each URL (when it was last updated, how often it usually changes, and how important it is, relative to other URLs in the site) so that search engines can more intelligently crawl the site.

Battelle kommentiert:

Overall, I’m thrilled. It took nearly a decade for the search engines to go from unifying around standards for blocking spidering and making page description to agreeing on the nofollow attribute for links in January 2005. A wait of nearly two years for the next unified move is a long time, but far less than 10 and progress that’s very welcomed.
