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 requires that inputs match the expected identifier structure. For identifier types with checksum algorithms, normalization also requires checksum-valid values. Inputs that do not meet these requirements yield NA_character_.

Normalized outputs are canonical, type-specific representations of valid identifiers.

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, checksum- failing, or structurally non-matching inputs yield NA_character_.
