For parliaments[edit]

In the case of a unicameral legislature (e.g. Parliament of Finland (Q643412)):

instance of (P31) : unicameral legislature (Q37002670)
country (P17)
applies to jurisdiction (P1001) (will be the same as the country (P17) for a national legislature, but not for sub-national)
has part(s) (P527) : the "Member of" position (see below)
Where known
<number of seats (P1342)>
<number of constituencies (P4253)>
<inception (P571)>
<location (P276)>
<image (P18)>
<official website URL (P856)>
Where appropriate
<replaces (P1365)>

For a legislature with multiple houses, an Item should exist for the legislature as a whole (e.g. Parliament of the United Kingdom (Q11010)), with instance of (P31): bicameral legislature (Q189445), and which then has part(s) (P527) the individual chambers (e.g. House of Commons (Q11005)), which link back in turn with part of (P361). Each should be an instance of lower house (Q375928) or upper house (Q637846) (or a subclass of either), if appropriate.

When adding country (P17) for a legislature, or chamber ensure that the correct country entity is used. This is usually straightforward, but be aware of cases like Denmark (Q35) vs Kingdom of Denmark (Q756617). For subnational legislatures, just copy the country (P17) used by the national level legislature(s).

When adding applies to jurisdiction (P1001) for a subnational legislature this should link to the geographic region/entity to which the legislature applies. For example for the Landtag of Brandenburg (Q521764), the applies to jurisdiction (P1001) would be Brandenburg (Q1208).

The item for the country should link to the legislature using legislative body (P194), for example:

If the legislative house has changed its number of seats over time, you can use start time (P580) and end time (P582) qualifiers on the number of seats (P1342) statement to provide date ranges. However, you may wish to instead use the number of seats (P1342) statements on the legislative terms instead, for historical data. The current seat count statement should have preferred rank.

For parliamentary terms[edit]

e.g. 55th Parliament of the United Kingdom (Q21084472) or 12th Riigikogu (Q967549)

instance of (P31) : Either:
inception (P571) (NB: when querying, some items still use start time (P580), though these should be migrated to P571)
dissolved, abolished or demolished date (P576) if ended (NB: when querying, some items use end time (P582), though these should be migrated)
applies to jurisdiction (P1001)
country (P17)
a series ordinal (P1545) qualifier to the instance of (P31) if the terms are numbered numerically
replaces (P1365) (NB: when querying, some items still use follows (P155), though these should be migrated to P1365)
replaced by (P1366) (NB: when querying, some items still use followed by (P156), though these should be migrated to P1365)
number of seats (P1342)

The inception is the date that the term started. Only rarely will this be the election date - usually the inception, or start date, of the parliament is on a different day, and that's the date that should be used.

The number of seats (P1342) statement should be qualified with applies to part (P518) pointing at a legislative house if the term applies to multiple houses.

Generalised base items (such as legislative term of the Riigikogu (Q21115902) should have:

subclass of (P279) : legislative term (Q15238777)
of (P642): the legislature
applies to jurisdiction (P1001)
country (P17)

Where there is a "List of Members" page for a term on a Wikipedia, the associated Wikidata page for the list (e.g. list of MPs elected in the United Kingdom general election, 2010 (Q4158639)) should have:

instance of (P31) : Wikimedia list article (Q13406463)
is a list of (P360) : the Membership Position
with qualifier
parliamentary term (P2937) : the term

and the term can link back to it with has list (P2354). For example:

For constituencies[edit]

Basic Information
instance of (P31) : electoral unit (Q192611) with a of (P642) qualifier to the legislature for which is is a constituency OR ideally, a legislature-specific subclass, such as constituency of the House of Commons (Q27971968), which should have a of (P642) qualifier to the legislature.
country (P17)
located in the administrative territorial entity (P131) : <the smallest administrative territory that includes this constituency>
inception (P571): <date constituency was created>
(and replaces (P1365) if this replaces one or more previous districts))
If available/known
geoshape (P3896): <link to shapefile>
electorate (P1831): <size of the electorate>
electoral district number (P4565): <official district ID>


A Legislature-specific base item (such as constituency of the House of Commons (Q27971968), or provincial electoral district of Quebec (Q2973931)) should show which legislature the districts belong to, how many there are (or have been at other times), and the country and jurisdiction in question:

For elections[edit]

The properties created so far have been collected in the {{Election properties}} template. See Wikidata:WikiProject elections.

For members of parliament[edit]

Many countries have specific identifiers for members of parliament. Constraints on these may define the model to be used for these members. New similar properties are very useful, and should be requested at Wikidata:Property proposal if an external site maintains a consistent and persistent list (i.e. IDs are unique over time, and do not disappear or get re-used after a member leaves office.)



All members should have relevant position held (P39) statements, according to the P39 model.
