Open Source License Checklists - Access to raw data

This is a description of how to access the raw data on which the OSADL Open Source license obligations checklists are based.

Each checklist, distinctly denominated by the license's SPDX abbreviation, is located under a link of the form<SPDX>.txt. Apart from all obligations and use cases, this material also contains all additional information, such as indications of copyleft clauses, patent hints and (in-)compatibilities with other licenses. All licenses for which checklists are available are listed below along with a link to the respective SPDX license text and to the checklist raw data file.

The checklists encode license obligations through a canonical vocabulary consisting of language elements (e.g. YOU MUST), actions (e.g. Provide) and terms (e.g. Copyright notice). Every word or expression is clearly defined, and the raw data of a particular definition is located under a link of the form<language,actions,terms>/<LANGUAGE,Action,Term>.txt. The explanation of the language element ATTRIBUTE, for example, is available under the link
