Measured tools (10)

• list_classifications read-only

  List classification families, versions, custodians, coverage and licensing notes. Start here when the correct standard is unknown.

  Parameters:

  • domain
  • status

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_classification read-only

  Get authoritative metadata and coverage for one classification_id returned by list_classifications.

  Parameters:

  • classification_id (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_codelists read-only

  List independent option lists within a classification before searching or exporting one list.

  Parameters:

  • classification_id (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• recommend_classifications read-only

  Return a deterministic ranked shortlist of all relevant classification concepts and codelists. Ranking supports user choice; it is not an automatic selection. Include answer options and context.

  Parameters:

  • question_text (required) — string
  • limit — integer
  • answer_options
  • survey_context

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_codes read-only

  Full-text search labels and notes. Results restrict to one option list only when codelist_id is explicitly supplied.

  Parameters:

  • query (required) — string
  • limit — integer
  • codelist_id
  • classification_ids

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_code_definition read-only

  Retrieve one exact code or codelist container, including its node_kind, hierarchy position and explanatory notes.

  Parameters:

  • classification_id (required) — string
  • code (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• browse_hierarchy read-only

  Browse top-level nodes or immediate children. Curated families return node_kind=codelist containers at root; pass that code as parent_code to browse its options.

  Parameters:

  • classification_id (required) — string
  • limit — integer
  • parent_code

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• validate_codes read-only

  Validate exact codes against one named classification version.

  Parameters:

  • classification_id (required) — string
  • codes (required) — array

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• map_codes read-only

  Apply official stored correspondences and expose splits, merges, changed meanings and unmapped codes. Never assume one-to-one equivalence.

  Parameters:

  • source_classification_id (required) — string
  • target_classification_id (required) — string
  • codes (required) — array

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• export_choice_list read-only

  Return a structured choice list at a selected hierarchy level. MICS exports require one codelist_id and never merge unrelated answer lists.

  Parameters:

  • classification_id (required) — string
  • level
  • limit — integer
  • format — string
  • codelist_id

  Hints: read-only yes · destructive no · idempotent yes · open-world no
