  • Patent number: 8037055
    Abstract: Methods and systems for a sitemap generating client for web crawlers are described. The client accesses one or more sources of document information about the documents available on a website, such as the file system, access logs, or pre-made URL lists. Document information is extracted from the sources and one or more sitemaps are generated based on the extracted document information. A notification is transmitted to a remote computer, informing that the sitemap(s) are available for access and likely have been updated. If the remote computer is associated with a web crawler, the remote computer may access the sitemap(s) and use the sitemaps to schedule a crawl of documents included or available on the website.
