Wikidata is a cousin of [[Wikipedia]]. Where Wikipedia focuses on long form prose articles, wikidata is a store of [[Facts vs Dimensions|facts]]. It is a “triplestore”[^1] that houses [[Subject-Predicate-Object|Semantic Triple]]s by the 10s of millions. Entities are denoted with a “QID”, which is just a [[Surrogate Keys|surrogate id]] prefixed with a `Q` Properties (i.e. relationships) are prefixed with `P`. Properties may have _qualifiers_, which are basically [[Subject-Predicate-Object]] triples where the subject IS a property of an entity. Like an arrow emanating out of another arrow in a graph. Qualifiers are sort of like extending from a binary to a trinary [[arity]]. ![[Pasted image 20240711161527.png]] **** # More ## Source - wikidata itself ## Related [^1]: Idon’t know enough to know if this is “technically correct”
