Ideas on priorities for Brightway development

Workshop of Brightcon 2023 to prioritize the mid- and long-term features to develop within the brightway ecosystem

In no particular order:

• support semantic web technologies (importing / exporting databases or data-packages)
• improve the existing means to share date (backup and restore projects is the most suitable today)
• full back and forth support with openlca
• full back and forth support with simapro

Recording a terminal session with ttyrec + ttygif

ttyrec is easy to install in many platforms

Use it inside the container, to produce the output file in a volume, and then use ttyrec to produce a GIF from the host.

• ttyrec - It's one apt install ttyrec away (or dnf)
• ttygif idem

Adding a new conda/mamba environment to a tljh ( The littlest Jupyter Hub ) that can be recognized by the tljh is done by adding ipykernel to the packages of the new environment.

• create the environment
• make sure ipykernel is added

sudo -E conda create -n new_env python=3 numpy pandas ipykernel

In theory, this can also be done in the jupyter lab terminal, as an admin user.
