title: Web Crawler for Linked Data in Java with Jena Library
body: <p>I have to implement a Web Cralwer that visits the Linked Data on the Web. I have built a simple functionality for that. I have three queries for that:</p>
  
  <ol>
  <li>What are the seed URIs I should use. The web sites which provide data in RDF format and follow Tim Berners Lee <a href="http://www.w3.org/DesignIssues/LinkedData.html" rel="nofollow">Linked Data principles</a> ??</li>
  <li>Generally what do you mean by round based approach for Web-Cralwers? I read about general       Web Crawlers and found that round based approach should be followed.</li>
  <li>I am able to parse only web pages which can return RDF/XML data .Is it sufficient to crawl the Linked Data.</li>
  </ol>
