Journal Article by Metadata

An OpenURL describing a journal article entirely through metadata, with no identifier. The form a resolver receives when no DOI is known.

Scenario

A source database wishes to refer the user to a journal article, but has no identifier (no DOI, no PMID) to attach. The OpenURL carries a complete set of descriptive metadata so that the resolver can match the citation against its knowledge base.

Notes

  • rft.au is repeatable — each additional author has its own rft.au parameter rather than being concatenated.
  • The first author is conventionally split across rft.aulast and rft.aufirst for higher matching accuracy, with subsequent authors going to rft.au.
  • Including both rft.spage/rft.epage and rft.issn increases the chance that a knowledge-base lookup will succeed even when titles vary in punctuation or transliteration.
  • Best practice is to include both an identifier and descriptive metadata when both are known.
