=head1 NAME

Bio::Chado::Schema::Result::Sequence::FeatureRelationship

=head1 DESCRIPTION

Features can be arranged in
graphs, e.g. "exon part_of transcript part_of gene"; If type is
thought of as a verb, the each arc or edge makes a statement
[Subject Verb Object]. The object can also be thought of as parent
(containing feature), and subject as child (contained feature or
subfeature). We include the relationship rank/order, because even
though most of the time we can order things implicitly by sequence
coordinates, we can not always do this - e.g. transpliced genes. It is also
useful for quickly getting implicit introns.

=head1 NAME

Bio::Chado::Schema::Result::Sequence::FeatureRelationship

=head1 ACCESSORS

=head2 feature_relationship_id

  data_type: 'integer'
  is_auto_increment: 1
  is_nullable: 0
  sequence: 'feature_relationship_feature_relationship_id_seq'

=head2 subject_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

The subject of the subj-predicate-obj sentence. This is typically the subfeature.

=head2 object_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

The object of the subj-predicate-obj sentence. This is typically the container feature.

=head2 type_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

Relationship type between subject and object. This is a cvterm, typically from the OBO relationship ontology, although other relationship types are allowed. The most common relationship type is OBO_REL:part_of. Valid relationship types are constrained by the Sequence Ontology.

=head2 value

  data_type: 'text'
  is_nullable: 1

Additional notes or comments.

=head2 rank

  data_type: 'integer'
  default_value: 0
  is_nullable: 0

The ordering of subject features with respect to the object feature may be important (for example, exon ordering on a transcript - not always derivable if you take trans spliced genes into consideration). Rank is used to order these; starts from zero.
