Apps built with Ozone gets to use the Ozone API and integrate with other apps in the Ozone Instance.

Application locations

Applications are stored as folders within the Ozone VFS. An application path will be determined as follows:

/ system / apps / author_name / app_name

In which the author name and the app name are provided from the application manifest file during its installation.

App Tags

An app tag is a term used for representing and identifying unique applications. An app tag is just " author_name / app_name ". App tags must be unique. It is the duty of application providers to address duplicate app tags.

Manifest File

Ozone Shell requires every app to have a manifest file about itself which describes what the app needs. It should be provided in a file named manifest.json in the app's root. You can also use the manifest file as a PWA manifest.

A manifest file is a JSON file, the required fields for Ozone are as follows:

1. name : A name for your application
2. author : The name of the author of the application
3. icon: (optional) an SVG HTML string of your app's icon
4. permissions: (optional) an array of permission namespaces your app requires
5. landing: the initial page of the application.
6. sources: a list of all files that must be provided to your application.
7. version: version number of your application
8. handle: (optional) app handles are specific keys other apps can reliably call for specific functionality.

Some of these fields are used for installation only, like the sources, handle, name, author and permissions. If the permissions key is empty, and the application still calls an Ozone API that requires permissions, Ozone would show a dialog asking the user whether to allow that specific permission for that application.
