Is my document indexed by Swoogle?

Is my document indexed by Swoogle?

“Swoogle has indexed millions of Semantic Web Documents, but how do I know that mine has been indexed?” Here is a simple way – please try your URL using Swoogle Track Back Service. Here I list several example to show how it works:

  • It helps us track the evolution of an ontology – say the protégé ontology
  • http://protege.stanford.edu/plugins/owl/protege

  • Finally, this service may also help us learn the life cycle of a semantic web document: it was created, actively maintained, lingered around for a while and finally died (i.e. went offline).

NOTICE: Yesterday we posted a form that direct you to Swoogle trackback service. Unfortunately, the form failed when it was called outside our firewall because a Swoogle API key is required. We didn’t notice at first, because we were inside the firewall when we tested it. When we did, we deleted the post, but PlanetRDF had already picked up the post and it was still in our database. Now the form has been removed, but you can definitely go to swoolge web site and try trackback service there.
