{{Wikidata:WikiProject NZThesisProject/Tab header}}
== '''<big>Data schema and exemplar items</big>''' ==
The data schema is detailed in three tables showing the properties we use on the thesis item, the author item and the advisor item.

== Schema for a thesis item ==
Note that on Wikidata a thesis is entered as a '''work level item''' (rather than an edition) which means that if there are multiple copies of a thesis in different university libraries, there may be multiple values for some properties e.g. Handle ID or DOI. See [[Wikidata:WikiProject Books#Bibliographic properties]] for general differences between work level and edition level items on Wikidata.

'''Label:''' the title of the thesis (shortened to 249 characters if necessary, with an ellipse to show it has been shortened)

'''Alias:''' if the title contained a spelling or keying mistake, put the incorrect one(s) here, or can also use for alternative titles if the author added more than one

'''Description:''' "Year thesis type by Author at Institution" e.g. "1998 doctoral thesis by Jane Smith at the University of Otago"

Where an item is its own reference, a source is not needed for every statement (see [[Help:Sources#When to source a statement]]) but there should be some reference or identifier somewhere on the item that links to a place where the information can be checked (in most cases that is the metadata in an institution repository, but it may sometimes be a catalogue record instead).

|text string
|{{Q|Q112954596}}
|The full title is entered here, even if it had to be shortened for use as the label. If the original title contained a spelling mistake, enter the corrected version as an alias for the Wikidata item of the thesis.
|-
|{{P|P50}}
|Wikidata item for author
|{{Q|Q111991156}} has author {{Q|Q111361935}}
| If (rarely) there is more than one author, use qualifier {{P|1545}} to show order.
Use qualifier of {{P|1932}}}  on the author/author name string statement to show how the name was represented in the original metadata from the repository (which may be different to the name on the front of the digitised thesis)
|-
|{{P|2093}}
|Contains author name string. 
|{{Q|Q112835799}} has author name string 'Raymond A Connolly'
|Qualifier of {{P|1932}}} shows how name appeared in original source if different.

Replace with {{P|50}} when author item created (items should not have both a {{P|P50}} and a {{P|P2093}} for the same person)
|-
|{{P|921}}
|Wikidata item for primary topic(s) of work
|{{Q|Q111991156}} has main subject {{Q|Q8609}}
|
|-
|{{P|123}}
|Wikidata item for repository that published the thesis metadata
|Possible values are:

{{Q|Q111174480}}<br>
{{Q|Q111174567}}<br>
{{Q|Q111174468}}<br>
{{Q|Q111173606}}<br>

{{Q|Q52662240}}<br>
{{Q|Q111174485}}<br>
{{Q|Q111174556}}
|Publisher of metadata is included as sometimes that is at a different institution than the thesis was submitted to, e.g. {{Q|Q112899643}}.
|-
|{{P|4101}}
|Wikidata item for university or polytechnic the thesis was submitted to
|{{Q|Q111991156}} was submitted to {{Q|Q1201513}}
|Some theses may be submitted to more than institution (e.g. see {{Q|Q112899643}}). 
If the name of the institution has changed since the thesis was submitted, an {{P|1932}} qualifier is useful although raises a constraint violation.
|-
|{{P|291}}
|Wikidata item for geographical place of publication
|{{Q|Q112907878}} was published in {{Q|Q200028}}
|

|Wikidata item for language associated with the work
|{{Q|111965271}} has language {{Q|36451}}
|Can have more than one value if a thesis is written in more than one language
|-
|{{P|577}}
|Point in time a thesis was published (not publication date of the metadata)
|{{Q|111965271}} was published in 2000
|Precision may be day/month/year if known, month/year or most commonly just year
|-
|{{P|953}}
|URL for the full work, if available
|{{Q|111965271}} full work available at https://mro.massey.ac.nz/handle/10179/1117
|For embargoed works, add qualifier {{P|P11140}} if a date for the end of the embargo is known

|
|-
|{{P|3931}}
|Wikidata item for the copyright holder
|{{Q|111965271}} has copyright holder {{Q|66310530}}

|{{P|9161}}
|The advisors or supervisory committee on the thesis, if known (if roles are known, qualifiers can be added)
|{{Q|112692889}} has thesis committee member {{Q|90697092}}
|This property is useful for linking advisors to the thesis, until such time as the thesis author is disambiguated and can be linked to the advisors directly.
