Library Carpentry Wikidata: Key Points

What is Wikidata?

Wikidata entities are known as Items, and each item is displayed on a page that is identified with the item’s “Q” number
Statements are assertions about items, which state relationships between items using wikidata properties.
Relationships between entities are known as Properties, and each property is identified with a “P” number
Statements are also known as “triples”
Wikidata and Wikipedia are complementary, but Wikidata is focused on basic claims or assertions, not descriptive or narrative information

Triples are the basic data structure of graph databases, and they are the conceptual structure of Wikidata statements.
Wikidata items are denoted by a human-readable label and a short description, and a unique identifer that begins with a Q. These items are the subjects of linked Wikidata statements.
Wikidata defines relationships between items, also known as triple predicates, with Wikidata properties.
Wikidata statements can capture library information, such as relationships like creatorship, publication, aboutness, and more.
