Getting Started edit

You can experiment with Listeria on your own user page Special:Mypage or create a subpage of your user page Special:Mypage/Listeria

SPARQL Queries for generating lists edit

You'll need a SPARQL query to use. You can use your own or try and/or adapt this one:

The following query uses these:

Items: human (Q5)   , suffragist (Q27532437)

Properties: instance of (P31)   , occupation (P106)  
```
SELECT ?item WHERE 
{
  ?item wdt:P31 wd:Q5.
  ?item wdt:P106 wd:Q27532437.
}
```

Try it!

Query Resources edit

Introduction to Querying Wikidata with SPARQL video tutorial - easy to follow in depth introduction

Building SPARQL Queries by Navino Evans

wikibooks:SPARQL - great reference for creating SPARQL queries

Wikidata:Request_a_query - you can try requesting a query if you are having trouble creating one

Listeria edit

Now on your user page or the subpage you've created use the Wikidata List template with your SPARQL query:

{{Wikidata list
|sparql= SELECT ?item WHERE
{
  ?item wdt:P31 wd:Q5.
  ?item wdt:P106 wd:Q27532437.
}
|wdq=
|sort=P570
|columns=label:name,P18,description,P569,P570,P106,item
|thumb=70
|min_section=2
|summary=itemnumber
}}




{{wikidata list end}}

See page 4 of Rob's presentation for an explanation of the template: https://commons.wikimedia.org/wiki/File:Listeria_presentation_LD4_Wikidata_Affinity_Group_2020.pdf

Remember you must use the variable ?item in your query.

Questions edit

Each Listeria template needs to be on a separate page.

However, you can pull in a Listeria template from one page to another.

Example: https://en.wikipedia.org/wiki/Wikipedia:Meetup/DC/From_Field_to_Lab:_Writing_(Wikipedia)_Histories_of_the_USDA%27s_Women
- {{Wikipedia:Meetup/DC/From Field to Lab: Writing (Wikipedia) Histories of the USDA's Women/ListA}}

You can use different Listeria templates in different tabs.

Example: https://www.wikidata.org/wiki/Wikidata:WikiProject_Vanderbilt_Fine_Arts_Gallery

There is not a header parameter to pull in a header for the template, but you could use Wiki text or do something like was done on this page:

Wikipedia:WikiProject_Women_in_Red/Missing_articles_by_education/US_-_land-grant_universities

How are people using Listeria?

Track progress in an editing project: can use on focus list of Wikimedia project (P5008)
Identify gaps in metadata Example: Wikidata:WikiProject_sum_of_all_paintings/Creator/Thomas_Sully
In Wikipedia, identify missing articles Example: Wikipedia:WikiProject_Women_in_Red/Missing_articles_by_occupation/Librarians
