Normalize scholarly identifiers

Source: R/normalize_scholid.R
normalize_scholid.Rd

Vectorized normalizer that converts supported scholarly identifier values to a canonical form (e.g., removing URL prefixes, labels, or separators).

Normalization is structural: inputs that conform to the expected identifier syntax are converted to a canonical representation. Inputs that do not match the required structure yield NA_character_.

For identifier types with checksum algorithms (e.g., ORCID, ISBN, ISSN), normalization does not verify checksum correctness. It only enforces structural plausibility and canonical formatting.

Use is_scholid() to test whether values are fully valid identifiers, including checksum verification where applicable.

Usage

normalize_scholid(x, type)

Arguments

x

A vector of values to normalize.

type

A single string giving the identifier type. See scholid_types() for supported values.

Value

A character vector with the same length as x. Invalid or structurally non-matching inputs yield NA_character_.
