Getting StartedEdit

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 listsEdit

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:

Query ResourcesEdit

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


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.

{{wikidata list end}}

See page 4 of Rob's presentation for an explanation of the template:

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


Each Listeria template needs to be on a separate page.

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

You can use different Listeria templates in different tabs.

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:

How are people using Listeria?
