# Workflow for building OGC application packages
#
# Steps:
# 
# 1. Parse the input algorithm config to retrieve the build parameters.
# 2. Generate the application package process cwl.
# 3. Build and publish the algorithm Docker image to GitLab
# 4. Build and publish the OGC application package to GitLab
