How does it works: concepts and global workflow

Concepts

To run the workflow properly, you need 3 items:

QGIS profiles

A scenario

The QDT executable

icon profiles

icon scenario

icon QDT

QGIS profiles

One of the most interesting aspects of QGIS when it comes to deploying it to a large number of users is the ability to provide them with one or more customised experiences via the profile system. A profile contains many settings: interface items, installed and deactivated plugins, variables, network settings, etc.

To facilitate their management and administration, QDT uses a profile definition file in JSON format (profile.json stored in the profile folder) which then serves as a “recipe” at the time of installation and especially when updating a profile.

Publish your QGIS profiles

Scenarios

Clearly inspired from Ansible and CI/CD platforms (especially GitLab CI, GitHub Actions), QDT uses scenario (YAML files) organised in sections, the main one allowing to define the tasks (called jobs) to be performed for the deployment.

Write your scenario


Functional workflow

Typical roles

  • GIS administrator: in charge of editing QGIS profiles and QDT scenarios

  • IT team: in charge of automating the QDT execution with its favourite tool

  • End-user: in charge of clicking on desktop Icons and playing with its favourite GIS software

Flow chart

List of jobs mentioned here is just an example. Every scenario can adapt its own jobs to apply.
