Steffen,

Also, can I nudge you into using <link/> to expose links to the data 
sources behind the visualizations? A SPARQL Construct or Describe URLs 
will do. You can see examples of what I mean via URI Debugger output below:

1. 
http://linkeddata.informatik.hu-berlin.de/uridbg/index.php?url=http%3A%2F%2Fdbpedia.org%2Fpage%2FLinked_Data&useragentheader=&acceptheader= 
- Linked Data Description (Green Page)

2. 
http://linkeddata.informatik.hu-berlin.de/uridbg/index.php?url=http%3A%2F%2Fdbpedia.org%2Fdescribe%2F%3Furl%3Dhttp%3A%2F%2Fdbpedia.org%2Fresource%2FLinked_Data&useragentheader=&acceptheader= 
- Linked Data Description (Blue Page -- which leverages 
.well-known/host-meta for discoverable URL templates etc..) .

Goal is to loosen the coupling between the visualization and its data 
sources in a Web user agent friendly way.
