Especially looking for users of ob-lilypond:

I currently have a few LilyPond source code blocks that are working quite well as inline graphics (exported to LaTeX), e.g.:

#+BEGIN_SRC lilypond :exports results :noweb yes :file ex1.eps
...
#+END_SRC

When I export, it (correctly) asks if I want to evaluate the source block, and the export (correctly) includes the line:

\includegraphics[width=.9\linewidth]{ex1.eps}

So far, so good.

Now, I would like to make the results a floating figure, with a caption and a #+name reference. So I added the following to the above block:

#+name: ex1
#+caption: One possible form of "seed" material to start the performance.
#+BEGIN_SRC lilypond :exports results :noweb yes :file ex1.eps
...
#+END_SRC

... but the #+name is not converted into a label, and the #+caption is also ignored.

My question, then, is: What is needed to get ob-lilypond to support LaTeX floats and captions? (I have a sneaky feeling it isn't trivial, but it's worth asking in any case.)

You are applying the name and caption to the source block, which is
removed (:exports results), not to the results of the source block. So,
you need to generate the results first, or at least put a RESULTS
keyword below, and apply the name and caption to it.

A-ha. Thank you. So, "What is needed to get ob-lilypond to support LaTeX 
floats and captions" is to RTFM ;)

I have often exported source code to LaTeX listings, but only infrequently 
exported results. So I wasn't clear on the mechanism. Now that you explain 
it, it makes perfect sense: the properties belong to an entity that I asked 
it not to export.

Thanks again - I can take it from here.

(PS This project is a write-up of an improvisational composition -- a lot 
of text description of the procedure, with some examples in musical 
notation along the way. It blows my mind that I can write the lilypond 
scores directly into the org document, and it all renders with C-c C-e l p. 
org-mode FTW! Again!)
