#
# $c->{datasets}->{foo} = {
# 	name => "foo", # name
# 	type => "LocalFoo", # data object class
# 	sqlname => "foo", # database table name
# };
#
# See EPrints::DataSet for documentation on dataset properties.
#
# You probably want to define the data object class in a separate file
# (but it must be in your Perl path).
# You could define the class object in a cfg.d file but you *must* enclose
# the entire package in a enclosure, or you will break EPrints.
