File description

summary

current release

  • release_date: obtained from release/metadata/release-date.json (or snapshot/metadata/release-date.json).
  • valid_terms: Total number of valid terms (non-obsolete) in the ontology.
  • obsolete_terms: Total number of terms with "obsolete" status (ie, term_ids for which the is_obsolete field is true in the go.obo file) (this excludes merges).
  • merged_terms: Total number of merged terms (calculated by counting the term_ids for which the field is_obsolete is true in the go.obo file, and that also are are as alt_ids of a valid term).
  • biological_process_terms: Total number of valid terms for the biological_process aspect.
  • molecular_function_terms: Total number of valid terms for the molecular_function aspect.
  • cellular_component_terms: Total number of valid terms for the cellular_component aspect.
  • meta_statements: Total number of identifiers, alternative identifiers, namespace, term label, comments, synonyms, definitions, subsets, for each valid term.
  • cross_references: Total number of cross_references, from the xref field of the go.obo file.
  • terms_relations: Total number of relations; the count of all relations, using the fields is_a, intersection_of and relationship of the go.obo file.

Same information as for the current release.

changes

  • created_terms: Number of terms created since the last release.
  • obsolete_terms: Number of terms obsoleted since the last release (this excludes merges).
  • merged_terms: Number of terms merged since the last release
  • biological_process_terms: New biological_process terms.
  • molecular_function_terms: New molecular_function terms.
  • cellular_component_terms: New cellular_component terms.
  • meta_statements: Total number of changed meta statements.
  • meta_statements_by_term: Number of terms with changed meta statements.
  • cross_references: Number of changed cross-references.
  • cross_references_by_term: Number of terms with changed cross-references.
  • relations: Total number of changed relations.
  • relations_by_term: Number of terms with changed relations. RIGHT???????????
