Creates an array in form_state containing the existing relationships. This array is then modified by the add/remove buttons and used as a source for rebuilding the form.

$form_state['chado_relationships'] = array( '[type_id]-[rank]' => array( 'object_id' => [the _relationship.object_id value], 'object_name' => [the base_table.uniquename value linked on base_foreign_key=object_id], 'subject_id' => [the _relationship.subject_id value], 'subject_name' => [the base_table.uniquename value linked on base_foreign_key=subject_id], 'type_id' => [the _relationship.type_id value], 'type_name' => [the cvterm.name value linked on type_id], 'rank' => [the _relationship.rank value], ), );
