| * Display the basic information in a FOAF document | |
| * | |
| * The example starts by loading the requested FOAF document | |
| * from the web. It then tries to work out if the URI given | |
| * was for the person or the document about the person. | |
| * | |
| * If a person is found, then the person's name, homepage | |
| * and description are shown, along with a list of the | |
| * person's friends. | |
