Wikidata Claims

The statements about every Wikidata item and property: one row per statement, with its value, rank, qualifiers and references.

Files

Files are at all/part-{i}-of-{n}.parquet. Rows are sorted by id across the files, in string order (Q10 comes before Q2), so a filter on id reads only the row groups whose id range can hold it. An item's statements keep their order in the source.

Unlike the other tables, claims are not split by language: a statement has no language of its own, only the names of the things it refers to do. Those names are in wikidata-claims_labels, split by language, for you to join in the languages you want. A monolingualtext value carries its own language, in datavalue.language.

Schema

Column	Type
id	string	The item (Q…) or property (P…) the statement is about
property	string	The statement's property, e.g. P31 (instance of)
datavalue	struct	Its value: see below
datatype	string	The property's datatype, e.g. wikibase-item, quantity, time, external-id
rank	string	preferred, normal or deprecated
qualifiers	list of {key, value}	Qualifiers, grouped by property: key is the property, value a list of snaks
references	list of lists of {key, value}	References, each a list of snaks grouped by property, as for qualifiers

A snak, in qualifiers and references, is a struct of property, datavalue and datatype, as in the statement's own columns.

datavalue

One struct holds the fields for every kind of value, and those not used by a value are null. It is null where a snak has no value (Wikidata's "unknown value" and "no value", which this table does not tell apart).

Fields	For
id	items, properties and other entities (wikibase-item, wikibase-property, ...)	The entity's id
datavalue__string	string values (string, external-id, url, commonsMedia, ...)	The string
text, language	monolingualtext	The text and its language
amount, upperBound, lowerBound, unit	quantity	The amount and bounds as decimal strings, and the unit
time, timezone, before, after, precision, calendarmodel	time	The timestamp, its precision and calendar model
latitude, longitude, altitude, precision, globe	globe-coordinate	The coordinates, their precision and globe

precision, latitude and longitude are structs with an integer and a float field (precision__integer and precision__number, and so on), since the source has both. Only one of them is set. altitude is always null.

Names

For each statement, qualifier or reference snak, the names in a language come from wikidata-claims_labels:

Name of	field	ref
the property	property-labels	property
the item it points to	labels	datavalue.id
the unit of a quantity	unit-labels	datavalue.unit

The subject of a statement (its id) is named in wikidata-labels. The wikidata-claims_labels card has a worked join.

Loading

There is one subset, all.

import polars as pl

claims = pl.scan_parquet("hf://datasets/permutans/wikidata-claims/all/*.parquet")
claims.filter(pl.col("id") == "Q42").collect()

from datasets import load_dataset

ds = load_dataset("permutans/wikidata-claims", streaming=True)

In total: 34 files, 17.7 GB of Parquet, 774,255,243 rows.

Snaks on deleted properties

The source has some snaks on properties since deleted from Wikidata (such as P450 and P4003), which it could not render fully. The datavalue is left as an error message, or the whole snak as just the property id. These are left out:

• a statement whose main value is one of these snaks is dropped;
• a qualifier or reference snak that is one is dropped, and so is a qualifier group or reference left empty.

There are very few of them. The pipeline keeps a record of each one it drops, but they are not published here.

The wikidata-pq tables

Six tables built from the same source by wikidata-pq, all keyed by Wikidata id:

Dataset	Rows	Split by
wikidata-labels	an item's or property's name, per language	language
wikidata-descriptions	its short description, per language	language
wikidata-aliases	its other names, per language	language
wikidata-links	its page title on each Wikimedia site	site
wikidata-claims	its statements	not split
wikidata-claims_labels	names of the properties, items and units its statements refer to, per language	language
