Sindice is by large the biggest search engine for the semantic web, thanks to our unique indexing system and to our advanced crawling technology, but it is not omniscient (yet).

If you are aware of an RDF source (or microformats or another of our supported formats) thats is not crawled yet, you can submit the URL here and we will index it in few hours.

If you manage an RDF knowledge base take a look at the semantic sitemap protocol that we developed and that is now accepted by most semantic web search engines. It will allow you to be indexed better and will save bandwidth and time on your hosting.

For any question you can ask us directly using our Forum
