Build tree for the IVOA vocabulary SKOS files.

You need:

  * rapper: from <http://librdf.org/raptor/>
  * cwm: you need the CVS version from
    <http://www.w3.org/2000/10/swap/doc/cwm.html>
  * BibTeX, to build the bibliography in doc/

Configuring and building
========================

  % autoconf
  % ./configure 'CWM=python "/path/to/checked out/cwm.py"'
  % make

(yes, autoconf is slightly over the top for a project which isn't
designed to be built after distribution, but it's the most
straightforward way to do the various substitutions required, avoiding
a lot of Makefile fuss).

The cwm command can be given as shown (which works from a checked out
but not installed SWAP), but note the quotes.  If you install cwm in a
standard python way, so that just 'cwm' at the command line works,
then setting this should be unnecessary (but I haven't been able to
work out how one is actually supposed to install cwm, so I can't
really check this).


Maintainance
============

To add a vocabulary:

  1. Create the appropriate subdirectory under src/, say src/NewVocab
  2. Add a Makefile.in in that directory which creates at least
     src/NewVocab/NewVocab.ttl, src/NewVocab/NewVocab.rdf and
     src/NewVocab/Notes.  The Makefile.in should allow its release
     information to be set in the same way that src/AOIM/Makefile.in (for
     example) does. 
  3. Add NewVocab to src/Makefile.in's SUBDIRS variable.
  4. Add the new Makefile.in to the bottom of configure.ac.
