public class StaticSitemapGenerator
extends GenericService
implements SitemapGenerator

Sitemap generator service that generates sitemap repository items in SitemapRepository for static pages. List of static pages sets in staticPages

This is an example of what will be generated:

 <?xml version="1.0" encoding="UTF-8"?>
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
 <url>
   <loc>http://www.example.com/</loc>
   <changefreq>monthly</changefreq>
   <priority>0.8</priority>
 </url>
 </urlset>
 

The available tags are described below:

• <urlset> - Encapsulates the file and references the current protocol standard.
• <url> - Parent tag for each URL entry. The remaining tags are children of this tag.
• <loc> - URL of the page. This URL must begin with the protocol (such as http) and end with a trailing slash, if your web server requires it.
• <changefreq> - How frequently the page is likely to change. This value provides general information to search engines and may not correlate exactly to how often they crawl the page. Valid values are:
  • always
  • hourly
  • daily
  • weekly
  • monthly
  • yearly
  • never
• <priority> - The priority of this URL relative to other URLs on your site. Valid values range from 0.0 to 1.0.

For additional information see Sitemap protocol
