Help:QID
From MaRDI portal
A QID refers to an identifier starting with the Latin letter Q as used on Wikibase instances like the MaRDI portal (i.e. the wiki this page is on) or Wikidata. In these contexts, a QID is used to identify a specific concept or other entity, e.g. Q42 here refers to the concept of the Vandermonde Determinant.
Of note, any given QID is specific to its wiki, so corresponding entries in other Wikibase instances about the same concept would typically have a different QID for it. On Wikidata, for instance, the Vandermonde Determinant has the QID Q7914492. To minimize confusion, QIDs in the context of the MaRDI portal are frequently referred to as MaRDI QID.
