The "linking" ISSN for a journal or other publication is one of the "print" or "electronic" International Standard Serial Numbers, which has been selected to represent the resource in all media. It is usually the ISSN which was registered first, and defaults to the "print" ISSN number for a journal. Fatcat uses ISSN-L as the primary identifier for journals to reduce confusion and potential for duplication. The ISSN organization publicly publishes a mapping between linking and print/electronic ISSNs. {{ entity_macros.lookup_form("container", "issnl", "1234-567X", lookup_key, lookup_value, lookup_error) }} Must include the dash
Wikidata is the structured, machine-readable database that complements Wikipedia. Entities, which can include bibliographic entities like books and papers, are identified by a "QID". Fatcat also links container (journal) and creator (author) entities to Wikidata by QID. Anybody can edit Wikidata and create QIDs. {{ entity_macros.lookup_form("container", "wikidata_qid", "Q94324", lookup_key, lookup_value, lookup_error) }} Include the "Q" prefix.
