Application Resource

Before to start this article, review the Application Abstraction page.

Introduction

The App Resource covers the conceptual middle ground between the entire Model and the individual Installer! An App Resource is local to one Node: it specifies Installers to be put on the Node.

In order to specify parameters for all contained Installers, the App Resource can resort:

  • to (partially) fixed values,
  • to the parameters it requires itself,
  • to a number of properties of the Node it is installed on,
  • to exported values from App Resources related by Dependencies, Links, or Imports.
