PingtheSemanticWeb.com is a web service archiving the location of recently created/updated FOAF, DOAP or SIOC RDF documents on the Web. If one of those documents is updated, its author can notify the service that the document have been updated by pinging it with the URL of the document. PingtheSemanticWeb.com is used by crawlers or other type of software agents to know when and where the latest updated FOAF, DOAP and SIOC documents can be found. So it requests a list of recently updated documents as a starting location to crawl the semantic web.

It is extensible and upwardly-compatible with more sophisticated formats like the OGC GML (Geography Markup Language®).
