Documented and featured SPARQL queries[edit]
SPARQL queries are essential to explore the Wikidata database, get insights from Wikidata and check the quality of the data.
Right now, we can find queries in the following places :
- examples queries (Wikidata:SPARQL query service/queries, Wikidata:SPARQL query service/queries/examples)
- in user pages : many users have their own queries in their user space. See User:PAC2/SPARQL queries
- in WikiProjects : see Wikidata:WikiProject France/Queries for example.
- in the weekly newsletter : see Wikidata:SPARQL query service/qotw)
That's great but those queries are often poorly documented. They have a title but few explanations, context, insights, and there are few warnings or quality checks to know if the results are reliable.
I've recently made a proposal to create dedicated pages to document a query with a basic skeleton to explain the context, the quality checks, the construction of the query, etc. See User:PAC2/Documented queries.
A few years ago, there have been a proposal to create featured queries (see Wikidata:Showcase Queries). I think that we need both. Documented queries is just a template to document a query. If the documentation is high is of high quality, the query is optimised and the results are reliable, the query can be nominated as a featured query.
My proposition :
- Create a dedicated WikiProject to Documented and featured queries
- Documented queries can be created
- In a user space
- In a Wikiproject
- Anywhere in the Wikidata namespace
- All documented queries should be in the category : Category:Documented query
- Documented queries can be proposed to be featured queries. One need to create a new subpage with the discussion and the vote. This could be something such as User:PAC2/Query/List of current French departments/Featured query.
- If the vote is conclusive after a few weeks, the documented query can be considered as a featured query. (we may create a category and a small template with a barnstar.)
I think it's worth to have a discussion about this proposal instead of voting.
