Queries

Queries enable users to ask systematically for the wikis semantic data. Queries mostly use categories and properties, but also page names or namespaces to search for results, which can be displayed on several ways.

So, queries can be divided in two actions, which each can be defined by the user:

• Selecting pages
• Displaying results

Once defined, there are three ways to work with queries:

• query on the Special:Ask page
• embed as inline query
• save and embed as concept
