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

 123 ## Packagegroups
 124
 125 AGL DEMO Platform's
 126 [packagegroups](https://www.yoctoproject.org/docs/3.1.2/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks)
 127 consist of the following:
 128
 129 ### packagegroup-agl-demo-platform
 130
 131 This packagegroup is used for generating the `agl-demo-platform` image,
 132 which is the full image for the AGL distributions IVI profile.
 133 You can see the recipe (i.e. `agl-demo-platform.bb`) that installs
 134 the `packagegroup-agl-demo-platform` packagegroup
 135 [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb).
 136
 137 As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs
 138 only `packagegroup-agl-demo-platform` and the packages of the DEMO applications.
 139
 140 ``agl-demo-platform`` contains the following three packagegroups:
 141
 142   * `packagegroup-agl-image-minimal`
 143   * `packagegroup-agl-image-ivi`
 144   * `packagegroup-agl-demo-platform`
 145
 146 ### packagegroup-agl-appfw*
 147
 148 These packagegroups contain packages for the AGL distribution's
 149 Application Framework.
 150 Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which
 151 should hold sufficient packages for the Application Framework.
 152
 153 Subsystems also can maintain their own packagegroups using appropriate
 154 `recipes-*/`.
 155 For example, Qt5 has two packagegroups in `meta-agl-demo`:
 156 `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`,
 157 which are under `recipes-qt/`.
 158
 159 The `packagegroup-agl-appfw-native-qt5` is included by
 160 `packagegroup-agl-appfw-native` because Qt5 belongs to native application
 161 framework of AGL Distro.
 162
 163 Because the `packagegroup-agl-demo-qt-examples` is not mandatory for
 164 the AGL Application Framework and the AGL DEMO, the packagegroup is added
 165 to the layer's `local.conf` file only when needed.
