 -  :doc:`Analyzing data flow in Java <analyzing-data-flow-in-java>`: You can use CodeQL to track the flow of data through a Java program to its use. 
 
+-  :doc:`Using data extensions to model your Java/Kotlin dependencies`: You can model frameworks and libraries that your code base depends on using data extensions and publish them as CodeQL model packs.
+
 -  :doc:`Java types <types-in-java>`: You can use CodeQL to find out information about data types used in Java code. This allows you to write queries to identify specific type-related issues.
 
 -  :doc:`Overflow-prone comparisons in Java <overflow-prone-comparisons-in-java>`: You can use CodeQL to check for comparisons in Java code where one side of the comparison is prone to overflow.
