I was thinking of a user defined schema or ontology for a wiki, allowing the user to also create simple queries for their own data.  The example data for a lot of GraphQL tools is Star Wars characters, movies and space-ships.  If you look at the Star Wars wiki, it can get a lot more complicated, but it&#x27;s not something you would want to hard code because new types and relationships are being added all the type.  The simplicity of the schemas and queries in GraphQL, and the existence of UI tools out of the box, it seems a lot more approachable than something like WikiData or Semantic Mediawiki.
