Wikidata Properties are specific attributes used to describe items in the Wikidata knowledge base. Each property has a unique identifier and a label, allowing users to define relationships and characteristics of items, such as date of birth or country of citizenship. These properties help organize and connect data across various topics. Properties are essential for creating structured data, enabling efficient querying and retrieval of information. For example, the property instance of can link an item like Eiffel Tower to its classification as a monument. This structured approach enhances the usability and interconnectivity of data on Wikidata.
