I think that it would be very useful to have as well some information on
the properties of the various transforms.  Some of this information is
already on the pages, but it would be useful to state whether each
transform is:

1/ lossy, 
   i.e., all the information in the RDF graph is contained in the JSON, 
2/ complete, 
   i.e., every RDF graph can be transformed into JSON,
3/ onto,
   i.e., every JSON document can be transformed into RDF by the inverse
   of the transform.
