* 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. | |
