:::::::::::::::::::::::::::::::::::::: questions

- What licenses are required for datasets or data products that are used?
- What licenses should we apply to created datasets?

::::::::::::::::::::::::::::::::::::::::::::::::

::::::::::::::::::::::::::::::::::::: objectives

- Understand how to classify source code and data (input, intermediate assessment, final assessment)
- Understand recommended licenses for each data type and code

::::::::::::::::::::::::::::::::::::::::::::::::


## Introduction

The content of this lesson is taken from the
recommendations from the IPCC Task Group on
Data Support for Climate Change Assessments
[(Huard et al 2022)](https://zenodo.org/records/7431834).

Licensing of IPCC material, with clear and consistent meaning in all legal jurisdictions, is essential to facilitate its
appropriate use to address pressing climate change challenges, while protecting the rights of data providers.

::::::::::::::::::::::::::::::::::::: callout

The IPCC reports and data are licensed separately!

IPCC reports are published under a copyright license that prohibits commercial use and the creation of derivative
products, unless discussed first and then given permission by the IPCC Secretariat. This license is applied to protect IPCC reports from distortion since these are accepted by member
governments, or approved in the case of the Summary for Policymakers, and adopted in the case of the Synthesis
Report. If the same license was applied to data products, it would severely limit their usefulness and value. A different
IPCC data license is required to allow the creation of derivatives for the pursuit of research and the re-use of IPCC
data-based products for national assessments, adaptation and mitigation policies.

::::::::::::::::::::::::::::::::::::::::::::::::

## Classifying Data Types

TG-Data distinguishes
three categories of data: input data, intermediate assessment data, and final assessment data.

Input data denotes the source data that underpins information in the assessment reports. It is typically authored by
credible, authoritative, trusted sources, who decide under which license it is published.

Intermediate assessment data is the outcome of data processing and analysis performed as part of the assessment
as an intermediate step in the generation of final assessment data. Data is only defined as intermediate if it has gone
through non-trivial processing to be considered an original product, distinct from the input data.

Final assessment data refer to data which is directly presented in data tables or graphically displayed (e.g. as a line
graph or a spatial map) in the report.

Source code refers to scripts, online code repositories, and software libraries written to create intermediate and final
assessed data, as well as the figures included in the reports.

## Licenses For Different Data Types

Input data shall be licensed under the
same license terms and conditions imposed by the data providers.
Input data copyright holders are encouraged to adopt well-known licenses enabling broad usage, including
commercial use, and avoid “ShareAlike” licenses.

Intermediate and final assessment data should be licensed under the Creative Commons Attribution 4.0
International (CC BY 4.0) license, where this does not infringe the interests of relevant license holders. The
Creative Commons family of licenses are designed to provide legal interoperability across virtually all jurisdictions.

When input datasets are published under restrictive licenses, waivers or exemptions can be sought for the IPCC
assessment reports. These waivers should be negotiated with copyright holders by Working Group co-chairs, with
guidance from TG-Data representatives.

These waivers would ensure that derivative products can be licensed by
the IPCC under CC BY 4.0, and that the version used by the assessment report is curated in a long-term archive,
either by IPCC DDC or another trusted data repository.
If exemptions cannot be obtained from the copyright owners, the
applicable licenses of input data will apply.

To ensure maximal reusability of source code, similarly to data, code should be published under permissive (non-
copyleft) open source licenses that do not restrict commercial use.


::::::::::::::::::::::::::::::::::::: challenge

## Challenge 1: Can you classify the following data types?

1. A map used in the report
2. Output from a CMIP6 model
3. Model agreement on changes in temperature in a warming scenario

:::::::::::::::::::::::: solution

## Output

1. A map used in the report: Final
2. Output from a CMIP6 model: Input
3. Model agreement on changes in temperature in a warming scenario: Intermediate

:::::::::::::::::::::::::::::::::
::::::::::::::::::::::::::::::::::::::::::::::::

::::::::::::::::::::::::::::::::::::: keypoints

- Data can be classified into input, intermediate assessment, or final assessment data.
- Input data shall be licensed under the
same license terms and conditions imposed by the data providers.
- Data produced as part of the IPCC assessment, be it intermediate or final assessment data, shall be published,
wherever possible, under the CC BY 4.0 license.
