Context Expression Extension overview
Use the DXA Context Expression Module to create Target Groups containing context expressions in Content Manager. Use the Context Expression Extension to publish such Target Groups to a presentation environment, where the Context Engine Cartridge can analyze them for your use on a webpage.
The Context Expression Extension framework consists of the following parts:
| Part | Description |
|---|---|
| Target Groups with context expressions | Run a DXA Context Expression module PowerShell script to create these Target Groups in Content Manager. The Target Groups contain context expressions that users can view and publish, but not edit, in Content Manager Explorer. |
| Context Expression Deploy and Undeploy Modules | These Content Deployer Modules extract the context expressions from their Target Groups and make them available on the Presentation Server. |
| Context Expression Cartridge | This Ambient Data Framework Cartridge picks up context expressions and forwards them to the Context Engine Cartridge for resolving. |
| Context Engine Cartridge | This Ambient Data Framework Cartridge resolves the context expressions and makes them available as Claims, which can be used to personalize your web content. |
