=head1 NAME

Bio::Ontology::DocumentRegistry - Keep track of where to find ontologies.
Allows lookups by name.

=head1 SYNOPSIS

  my $registry = Bio::Ontology::DocumentRegistry->get_instance();
  my($ont,$def,$fmt) = $registry->documents('Sequence Ontology');

  my $io = Bio::OntologyIO->new(-url => $ont,
                                -defs_url => $def,
                                -format => $fmt);
  my $so = $io->next_ontology();
  #...

=head1 DESCRIPTION

Do not use this directly, use Bio::Ontology::OntologyStore instead.
Bio::Ontology::OntologyStore uses Bio::Ontology::DocumentRegistry to
load and cache ontologies as object graphs, you can just ask it for
what you want by name.  See L for
details.
