The development of tutorials for the Open Energy Family takes place publicly in a dedicated tutorial repository. Please report bugs and suggestions as new issues. If Jupyter Notebooks are new to you and you'd like to get an introduction, have a look at this less than 10 minute introduction video. Official installation instructions are available on jupyter's readthedocs page.

In the field of information technology there are many licenses. Some cover multiple materials and domains, i.e. software, data or content while others only cover specific domains.
This tutorial aims to collect and describe existing and commonly used open data licenses.
Please note that there are different definitions of free, open, libre and what falls into open science data.
In general, open licenses grant the four freedoms, i.e. rights, that were originally defined for free software.
The main difference between open data licenes and free or open source software licenses, lies in the definition of the obligations that must be met in order to obtain the rights. There are already lists of open source licenses that guarantee the four freedoms. For example the Open Source Initiative (OSI) offers a list of approved licenses).
There are certain obligations that that a license may formalise, which will prevent the data from being considered open! The Open Knowledge Foundation has a section on non-conformant clauses. In brief, the main relevant clauses are:
Public domain is a concept in which no copyright or other protection like patents and trademark exists and thus no obligations are defined. In order to label and communicate this, a public domain license is useful! In some countries, like Germany, it is not possible to waive one's copyright. Specifically declaring a public domain license will ensure a legal status that is equivalent to public domain.
For more information see the international definition of public domain and the German/European Gemeinfreiheit.
Usecase: Data where no naming of the authors is required, e.g. "helper tables" for conversions.
Openness: As open as possible, but others can create non-open derivatives of it.

This obligation prescribes creating and placing an attribution string close to the created work. The string must contain the following information: 1. Title of the work, 2. Author(s), 3. Source (link) 4. License (Name of the license and a link to the license text). Be aware that this attribution string is different from the scientific citation string, which is necessary for good scientific practice.
Licenses that merely require an attribution are often referred to as permissive licenses
Usecase: Data where naming of the authors is required, e.g. "input and result data".
Openness: Open and suitable for acedemic work.

This obligation requires you to choose the exact same license for resulting data. It can be described as reciprocal, hereditary or (negatively connotated) virulent.

Usecase: Data where naming of the authors is required and all further updates must be open as well, e.g. "manual collection of technical parameters from factsheets".
Openness: Open and will be open forever.

If you find bugs or if you have ideas to improve the Open Energy Platform, you are
welcome to add your comments to the existing issues on GitHub.
You can also fork the project and get involved.
Please note that the platform is still under construction and therefore the design of this page is still highly volatile!
