NAME

FAST::Bio::Ontology::Term - implementation of the interface for ontology terms

SYNOPSIS

#get FAST::Bio::Ontology::TermI somehow.

print $term->identifier(), "\n";
print $term->name(), "\n";
print $term->definition(), "\n";
print $term->is_obsolete(), "\n";
print $term->comment(), "\n";

foreach my $synonym ( $term->each_synonym() ) {
    print $synonym, "\n";
}

DESCRIPTION

This is a simple implementation for ontology terms providing basic methods (it provides no functionality related to graphs). It implements the FAST::Bio::Ontology::TermI interface.

This class also implements FAST::Bio::IdentifiableI and FAST::Bio::DescribableI.

FEEDBACK

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

add_secondary_id

Methods implementing FAST::Bio::IdentifiableI and FAST::Bio::DescribableI

object_id

Title   : object_id
Usage   : $string    = $obj->object_id()
Function: a string which represents the stable primary identifier
          in this namespace of this object.

          This is a synonym for identifier().

Returns : A scalar

authority

Title   : authority
Usage   : $authority    = $obj->authority()
Function: a string which represents the organisation which
          granted the namespace, written as the DNS name for
          organisation (eg, wormbase.org)

          This forwards to ontology()->authority(). Note that you
          cannot set the authority before having set the ontology or
          the namespace (which will set the ontology).

Returns : A scalar
Args    : on set, the new value (a scalar)

namespace

Title   : namespace
Usage   : $string    = $obj->namespace()
Function: A string representing the name space this identifier
          is valid in, often the database name or the name
          describing the collection.

          This forwards to ontology() (set mode) and
          ontology()->name() (get mode). I.e., setting the namespace
          will set the ontology to one matching that name in the
          ontology store, or to one newly created.

Returns : A scalar
Args    : on set, the new value (a scalar)

display_name

Title   : display_name
Usage   : $string    = $obj->display_name()
Function: A string which is what should be displayed to the user.

          The definition in FAST::Bio::DescribableI states that the
          string should not contain spaces. As this is not very
          sensible for ontology terms, we relax this here. The
          implementation just forwards to name().

Returns : A scalar
Args    : on set, the new value (a scalar)

description

Title   : description
Usage   : $string    = $obj->description()
Function: A text string suitable for displaying to the user a
          description. This string is likely to have spaces, but
          should not have any newlines or formatting - just plain
          text.

          This forwards to definition(). The caveat is that the text
          will often be longer for ontology term definitions than the
          255 characters stated in the definition in
          FAST::Bio::DescribableI.

Returns : A scalar
Args    : on set, the new value (a scalar)
