Let's use the Docker image: postgis/postgis:13-3.1.

In classes metadata operation, class_parent_id returns null even if it exists.

Please, see the following comments:

• https://github.com/smurfix/flask-script

• https://blog.miguelgrinberg.com/post/migrating-from-flask-script-to-the-new-flask-cli

Tasks:

• Inform the right version in: lccs_ws/version.py
• Run all the tests.
• Create a branch named: b-0.6.
• From the branch b-0.6, create a tag named: v-0.6.0.
• In the master branch increase version in lccs_ws/version.py to 0.8.0
• Notify users that a new version is released.

The following error occurs when launching the instance using Dockerfile:

Failed to find attribute 'app' in 'lccs_ws'.

Should we rename the package ?

Land Cover Classification System Web Service (LCCS-WS) to Web Land Classification System Service (WLCSS) or
Web Land Classification Service (WLCS) ?

Add a lccs-ws-spec repository as a submodule of this repository.

Include the spec file under the folder doc/spec.
