This is the master version of the IVOA Ontology of Astronomical Object
types.

This was imported into the Volute repository in something of a hurry,
so that there are probably still defects in the way the documentation
is generated, and the ontology is to be curated (in particular, it's
not obvious that keeping the master version in Turtle is the best way
of doing this).  Blame Norman Gray, who's willing to spend more time
on this if anyone objects....

For general discussion, see the IVOA Note at

    http://www.ivoa.net/Documents/Notes/AstrObjectOntology/

and the collection of use-cases at

    http://www.ivoa.net/Documents/Notes/AstrObjectOntologyUseCases/

The master file is object-types.ttl.in.  This is a Turtle file (rather
than the RDF/XML file which is required by Protégé), because (i) this
is somewhat easier to edit by hand when necessary; and (ii) the
'rapper' conversion from RDF/XML to Turtle introduces some
normalisation, most notably alphabetising the names of classes, which
means that the file plays more nicely with the text-based diff which
Subversion uses, and so produces more informative diffs.

See check-uris.sh(.in) for the required redirections.  Use 'make
check' or 'make check-uris.sh; ./check-uris.sh' to run the checks.

The conversion to HTML, for documentation purposes, is not perfect;
amongst other defects, it's an XSLT conversion, so it depends on
non-guaranteed features of the serialisation to RDF/XML.  It's OK for
the moment, though.

There are various documentation properties included in the
object-types.ttl file.  These appear not to work well with Protégé
4.0, but they appear to work OK with 4.2+.

The first version committed here was from
http://www.ivoa.net/internal/IVOA/IvoaSemantics/ObjectTypes_1.500.owl

To adjust the location that the PURLs redirect to:
  * Change the HOSTHOST and HOSTBASEDIR variables in the Makefile
  * make webpage-tarball.tar.gz
  * unpack webpage-tarball.tar.gz on $HOSTHOST so that the
    object-types directory it contains matches $HOSTBASEDIR
  * make check

To make a new release:
  * adjust the version number in the variable VERSION within the Makefile
  * make webpage-tarball.tar.gz
  * unpack this on the machine $HOSTHOST in the directory $HOSTBASEDIR
  * make check
