NAME ^

Bio::Chado::Schema::Result::Cv::CvtermDbxref

DESCRIPTION ^

In addition to the primary identifier (cvterm.dbxref_id) a cvterm can have zero or more secondary identifiers/dbxrefs, which may refer to records in external databases. The exact semantics of cvterm_dbxref are not fixed. For example: the dbxref could be a pubmed ID that is pertinent to the cvterm, or it could be an equivalent or similar term in another ontology. For example, GO cvterms are typically linked to InterPro IDs, even though the nature of the relationship between them is largely one of statistical association. The dbxref may be have data records attached in the same database instance, or it could be a "hanging" dbxref pointing to some external database. NOTE: If the desired objective is to link two cvterms together, and the nature of the relation is known and holds for all instances of the subject cvterm then consider instead using cvterm_relationship together with a well-defined relation.

ACCESSORS ^

cvterm_dbxref_id

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

cvterm_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

dbxref_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

is_for_definition

  data_type: 'integer'
  default_value: 0
  is_nullable: 0

A cvterm.definition should be supported by one or more references. If this column is true, the dbxref is not for a term in an external database - it is a dbxref for provenance information for the definition.
