Source: R/database-write-mapping.R
mapping_metadata.Rd

Generate the required metadata for a mapping table. This is mainly used to generate the necessary metadata when adding a new mapping table to the database with add_mapping_table().

Usage

mapping_metadata(
  from_code_type,
  to_code_type,
  map_version = "v0",
  ...,
  from_col = "from",
  to_col = "to",
  map_source = NA_character_
)

Arguments

from_code_type

The type of coding system for the source codes (e.g., ICD-10, SNOMED-CT)

to_code_type

The type of coding system for the target codes (e.g., ICD-10, SNOMED-CT)

map_version

The version of the mapping metadata (default: "v0")

...

These dots are for future extensions and must be empty.

from_col

The column name for the source codes (default: "from")

to_col

The column name for the target codes (default: "to")

map_source

The source of the lookup metadata (default: NA_character_)

Value

A list containing the mapping metadata
