Semantic Compound Queries (a.k.a. SCQ) is a Semantic Mediawiki extension that defines the #compound_query parser function which can display results of multiple #ask queries (as compound construct) at the same time.



The recommended way to install Semantic Compound Queries is by using Composer with an entry in MediaWiki's composer.json or alternatively composer.local.json.

```json { "require": { "mediawiki/semantic-compound-queries": "~1.1" } } ```

  1. From your MediaWiki installation directory, execute composer require mediawiki/semantic-compound-queries:~1.1
  2. Navigate to Special:Version on your wiki and verify that the extension has been successfully installed.

Note that the required extension Semantic MediaWiki must be installed first according to the installation instructions provided with it.


The syntax of #compound_query resembles that of #ask, but with more than one query, and with the elements of each sub-query delimited by semicolons instead of pipes. Elements that are common across all sub-queries, like format= and width= (for maps) should be placed after all sub-queries.


A sample call to #compound query, which retrieves both biographies, along with their subject; and fiction books, along with their author; is:

``` {{#compound_query: [[Category:Books]] [[Has genre::Biography]] ;?Covers subject=Subject | [[Category:Books]] [[Has genre::Fiction]] ;?Has author=Author |format=list }} ```
