The prefixes improvement are good timing for me because some new
possible writers in
https://github.com/afs/riot-output
are making progress. Writers done, working on the registry and
extensibility.
(moved out of /Experimental so as not to cause many small commits to
clog things up - I'm just as happy to use svn/Experimental is you want
to see the fiddling about before first usable release)
It includes pretty TriG writing, pretty Turtle writing, N-triples and
N-Quads that should be faster (less string bashing, more buffering).
Faster URI to prefix name will be valuable. I was going to have to
worry about it and now I don't :-)
There is a PrintStreamRDF that does streaming output of Turtle (no
lists) and makes something easier to read than N-triples. I was going
to add it to the riot parser commands as an output option. This will be
performance critical.
