I'm having some issues with Lilypond 2.10.x's SVG export.
I seem to have fixed most (all?) of my font problems. I now have
another
problem, however.
In order to submit one of LilyPond's SVGs to e.g. the Wikimedia
Commons, it
is necessary to convert all of its text into paths; that way, users
need
not have LilyPond's fonts in order to view the image correctly.
Before
converting text into paths in Inkscape, you must make sure that none
of the
text is contained within a group. Therefore, I started to process my
file
by selecting everything and issuing an Ungroup command.
When I did so, the staff lines disappeared! Apparently every object
in the
file is in a one-element group. For some reason, ungrouping the staff
lines made them disappear—they were still present, just not visible.
I
think there may be an Inkscape bug at play here too, since "Select
All"
couldn't find the lines, but on the LilyPond end... how can I get
Lily to
create a sane, usable SVG file?
Any help is greatly appreciated here.
There's another approach to the SVG output problem: You can take PDF
or EPS
output from lilypond, and try to turn it into SVG files. The postscript
backend of lilypond is obviously more mature, and there exist
converters from
pdf/ps to svg. Free converters are a bit shaky, but for some lily
versions I
managed to convert .ly files into valid SVG via a chain of converters.
Usually, you need to first expand fonts to curves using some ps2ps-like
script, and then use pstoedit to convert to something that can be
converted
to svg. Unfortunately, most conversion tools are rather immature, so
you will
need some experimenting to make it work. IIRC, I managed to generate
valid
svg with this method for my master's thesis, using a lilypond version
around
2.6. I don't remember the exact combination of commands that worked
though.
(I have vague memories that it may be good to start with pdf output and
convert it back to eps)
Here's a script that works for some subsets of ps (not lily's though),
you can
look at it for ideas:

Ps2svg.sh
If you manage to find a fairly reliable path to convert the output of
a recent
lily version into wikipedia-usable SVGs, I'd be happy to know.
