      <strong>Info!</strong><br/>
    	<p>
      	Please be aware of that the simple file import via drag&amp;drop should only be used for smaller files.
      </p>
    	<p>
        All communication is done over HTTP and such there are several limiting parameters, for example, 
      the maximum body size a client may post against the webserver (e.g. tomcat, jetty or nginx default configuration is usually around 2 MBs). <br/>
      For loading larger datasets it is generally recommended to work either directly on the backend interface (e.g. Blazegraph) or to load the data via dedicated (but usually proprietary) triple store APIs. See also <semantic-link uri="http://help.metaphacts.com/resource/WorkingWithData"></semantic-link>.

    RDF files can be uploaded using drag&amp;drop field below. <br/>
    Clicking into the field will open the browser's default file selector.<br/>
