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.
