   5 ## Introduction
   6
   7 The `meta-agl-demo` layer is the reference user interface layer for the DEMO
   8 platform of Automotive Grade Linux (AGL).
   9 The layer provides a reference platform and applications.
  10 The BitBake target name for the DEMO platform is `agl-demo-platform`, which is
  11 the full DEMO platform image.

 119 ## Packagegroups
 120
 121 AGL DEMO Platform's [packagegroups](https://www.yoctoproject.org/docs/3.1.4/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
 122 consist of the following:
 123
 124 - packagegroup-agl-demo-platform
 125
 126     This packagegroup is used for generating the `agl-demo-platform` image,
 127     which is the full image for the AGL distributions IVI profile. You can see the
 128     recipe (i.e. `agl-demo-platform.bb`) that installs the
 129     `packagegroup-agl-demo-platform` packagegroup [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
 130
 131     As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
 132     only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
 133
 134     ``agl-demo-platform`` contains the following three packagegroups:
 135
 136       * `packagegroup-agl-image-minimal`
 137       * `packagegroup-agl-image-ivi`
 138       * `packagegroup-agl-demo-platform`
 139
 140 - packagegroup-agl-appfw*
 141
 142     These packagegroups contain packages for the AGL distribution's
 143     Application Framework. Subsystem should maintain
 144     `packagegroup-agl-appfw-[subsystem].bb`, which should hold sufficient packages
 145     for the Application Framework.
 146
 147     Subsystems also can maintain their own packagegroups using appropriate
 148     `recipes-*/`.
 149
 150     For example, Qt5 has two packagegroups in `meta-agl-demo`:
 151     `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
 152     which are under `recipes-qt/`.
 153
 154     The `packagegroup-agl-appfw-native-qt5` is included by `packagegroup-agl-appfw-native` because Qt5 belongs to native application framework of AGL Distro.
 155
 156     Because the `packagegroup-agl-demo-qt-examples` is not mandatory for the AGL
 157     Application Framework and the AGL DEMO, the packagegroup is added to the layer's
 158     `local.conf` file only when needed.
