The meta-dac-sdk layer defined some base classes (dac-image-wayland, dac-image-essos, dac-image-base ) several DAC image bbclasses App developer can start from ("inherit" in yocto terminology) to define its DAC application container image.

Yocto meta-dac-sdk layer introduce new types of OCI ImagesFollowing oci compliant base image types are defined :

• dac-image-base - for DAC application that run as system service without graphics output or user input. It inherits image-oci.bbclass from yocto meta-virtualization layer
• dac-image-wayland -  for for DAC application that are using OpenGL ES for 3D graphics using OpenGL ES2 as Graphics rendering API and Wayland-egl protocol to communicate with display serversetup EGL graphics surface and for key-input
• dac-image-qt - for DAC application that are using QT5  framework

• dac-image-essos  -  for for DAC application that are using Firebolt ® Essos frameworkusing OpenGLES2 as Graphics rendering API and Firebolt ® Essos to setup EGL graphics surface and for key-input

See below their hierarchy of inheritance  

Provided OCI Images are used as a base classes for specialized DAC Application OCI Images.

To create new OCI Image with application, developer had to define:
