Commons:Statements/it

Statements are a feature part of structured data. A statement is a structured way of recording information about a file. A statement consists of a claim, zero or more references, and a rank; a claim in turn consists of a property and either a value or one of the special cases "no value" and "unknown value", and zero or more qualifiers.

Una delle proprietà più comuni utilizzate negli statements è "soggetto". Molte altre proprietà possono essere usate; la tabella seguente elenca alcune delle più comuni su Wikimedia Commons
