Test scholarly identifier validity

Source: R/is_scholid.R
is_scholid.Rd

Vectorized predicate that tests whether values are valid scholarly identifiers of a given supported type.

For identifier types with checksum algorithms (e.g., ORCID, ROR, ISNI, ISBN, ISSN), checksum correctness is verified. The same checksum rules apply to normalize_scholid().

The main difference from normalization is input form: is_scholid() expects values in canonical (or near-canonical) form. Wrapped values such as URLs or prefixed labels should be normalized first with normalize_scholid().

Inputs that are NA yield NA. Non-matching values return FALSE.

Usage

is_scholid(x, type)

Arguments

x

A vector of values to test.

type

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

Value

A logical vector of the same length as x, indicating whether each element is a valid identifier of the specified type.
