* The source RDF data can either be fetched from the web

|
*
|
|
* The first thing that this script does is make a list the names of the
|
|
* supported input and output formats. These options are then
|
|
* displayed on the HTML form.
|
|
*
|
|
* The input data is loaded or parsed into an EasyRdf_Graph.
|
|
* That graph is than outputted again in the desired output format.
