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.
