Reuse a structured statement
Inspect the item, property, qualifiers and supporting reference before export.
Check first: Check dates and definitions; an unqualified value can refer to another context.

Is a value enough without qualifiers and references?
- Label
- Find an item; distinguish namesakes.
- Statement
- Read property, value, qualifiers and references.
- Check that the item identifies the intended person, place or object.
- Examine the statement’s context, including its period.
- Open its reference to check what it actually establishes.
Fictional example: a staff count has a “2018” qualifier. Keep that year in your note; do not present the value as the current count.
Your useful record: Keep item identifier, property, value, qualifiers and consulted reference.
A reference attached to a statement also needs reading and context.

Check the statement instead of copying a label
Wikidata is a collaborative structured knowledge base. An entity contains statements with properties and values; qualifiers and references supply context to examine. The displayed label alone does not convey all this information.
- Entity
- Retain the consulted item identifier.
- Statement
- Read property, value, qualifiers and references.
- Use
- Open the cited source before repeating a sensitive fact.
- Rank and reference
- Normal, preferred and deprecated ranks organise values for a property. They do not replace a reference or reading date and method qualifiers.
- Historical value
- A correct historical value can remain useful with its time period. Do not treat it as an error merely because a newer value exists.
- Values returned by default
- When a property has preferred-rank values, views and queries using best-ranked values can omit normal-rank statements. A value missing from a simplified result may remain in the detailed statements.
Source: Wikidata — Ranking · consulted on - Several preferred values
- Several statements can share preferred rank. Rank alone is not a numerical confidence measure: compare references, qualifiers and context for each value.
Source: Wikidata — Ranking · consulted on - Rank and references
- Preferred, normal and deprecated ranks help select values and communicate consensus. Rank does not replace the reference showing where a claim comes from.
Source: Wikidata — Help:Ranking · consulted on - Historical values
- An old value that was correct for its period is not automatically deprecated. Start and end qualifiers can describe that period.

Are different values necessarily duplicates?
No. They may concern different dates or contexts. Compare qualifiers and references before merging.
