Match candidate records against a set of records by strong identity

ztMatches.Rd

Nominates pairs whose normalized DOI, MD5 or title coincide and judges each pair with zotSameItem(). The result reports every nominated pair with its verdict, as ztTwins() does within one set, so a nominated title collision that is not a match remains visible.

Usage

ztMatches(candidates, records)

Arguments

candidates, records

Lists of records, or data.frames with one record per row, in any shape zotIdentity() accepts.

Value

A data.table with index (position in candidates), candidate (its key, or NA), itemKey, library, match and basis.

zotIdentity(), zotSameItem(), ztTwins().

Examples

Candidates <- list(list(title = "Paper", year = "2026", author = "Lovelace"))
Records <- list(
  list(key = "R1", library = list(type = "user"),
       data = list(title = "Paper", date = "2026",
                   creators = list(list(creatorType = "author",
                                        lastName = "Lovelace")))),
  list(key = "R2", data = list(title = "Paper", date = "1999"))
)
