I've merged in the (very extensive) metadata changes discussed earlier.
If you are brave, you can try them. But before you can 'cabal install'
the latest pandoc, you'll need to install the git version of
pandoc-types and then recompile citeproc-hs. This procedure should work:
git clone git://github.com/jgm/pandoc.git pandoc
cd pandoc
git submodule update --init
git clone git://github.com/jgm/pandoc-types.git pandoc-types
cd pandoc-types
cabal install
cd ..
darcs get http://gorgias.mine.nu/repos/citeproc-hs/
cd citeproc-hs
cabal install
cd ..
cabal install
The implemented system is a bit different than what I described before
(and not yet documented at all). Markdown files can have a YAML
metadata block, but it must come at the very beginning of the file.
(Previously I'd considered allowing metadata anywhere in the file,
but I'm not sold on that -- external tools really wouldn't find metadata
that is not at the beginning of the file useful, because you'd have
to parse markdown to discover which sections were metadata. I'm still
considering this issue.)
One nice thing about this new system is that you can, for example,
have a letter.latex template with fields like $to$, $salutation$,
$closing$. Then a letter can begin with:
---
to: |
| Mr. John Smith
| 25221 Lana Lane
| Gotham, XY 23423
salutation: Dear John,
closing: Yours sincerely,
...
(text of letter here)
And you can just do
pandoc --template letter myletter.txt -o myletter.pdf
to get a nicely typeset letter.
Because the metadata values are structured, you can also do things
like this (though you'll need to adjust templates to support it):
---
author:
- name: John Doe
affiliation: University of Western Tasmania
- name: Sarah Smith
affiliation: National Institute of Health
...
Your template can then contain something like this:
$for(author)$
$author.name$ ($author.affiliation$)
$endfor$
I have not yet implemented the YAML blocks in the markdown writer,
but I plan to do that in time.

I suppose you can still have the metadata in a separate file as
long as pandoc sees that file first?
pandoc --template foo metadata.yaml bar.mkd -o bar.pdf
What about concatenating several source files which all have
YAML blocks at the beginning. Will pandoc ignore them, filter
them out or what?

command line and in-file?

Yes.

Currently pandoc would try to parse the YAML blocks inside
the file as text.

Currently pandoc does a "merge." So, if you have an "author"
defined in metadata, and you specify an additional "author"
variable on the command line, pandoc will behave as if you
had given a list of two authors.
I'm really not sure what the optimal behavior is here.
