4.3 library(semweb/rdf_http_plugin): Reading RDF from a HTTP server

This module allows for rdf_load('http://...’. It exploits the library library(http/http_open.pl). The format of the URL is determined from the mime-type returned by the server if this is one of text/rdf+xml, application/x-turtle or application/turtle. As RDF mime-types are not yet widely supported, the plugin uses the extension of the URL if the claimed mime-type is not one of the above. In addition, it recognises text/html and application/xhtml+xml, scanning the XML content for embedded RDF.
