[goodrelations] XML Sitemap Generators

Dear all:

XML Sitemaps are an important part of using GoodRelations in shop sites, because they eaae the effective crawling of your site.
Here are two links with tools that help generate respective sitemap files:


A related tool is


This helps generate proper sitemaps for RDF content.

I think I have said this before, but again: If you publish a sitemap for your site, please try to indicate the proper date and time of the last modification for each resource (using the "lastmod" attribute in the sitemap). Some simple sitemap tools use the date of generating the sitemap for all entries instead of the actual date for each resource from the resource's meta-data. This means that your complete site has to be crawled anew each time you generate a new sitemap.

This is a lesser problem for a small or medium-size site (less than 5,000 pages / articles), but a major issue if your site has tens of hundreds of thousands of pages.

Best wishes

Martin Hepp
