I'm more-or-less ignorant of the technical issues here, but at a  
surface level the presentation syntax given in example 2 of the FLD  
appears to have some arbitrary differences from SPARQL, eg the use of
    abbr expands into uri
instead of
    PREFIX abbr: <uri>
and the use of ()s for grouping, as opposed to {}s, and some of the  
operators being prefix and some being infix.

There may well be cultural reasons for this syntax, but I expect many  
people to want to work with both syntaxes, and some commonality might  
be helpful in reducing the learning curve.
