Open data of logically decomposed OSS licenses.
We publish the logically decomposed OSS licenses as open data in order to make it easy for people to understand OSS licenses. We believe it contributes to development of OSS.
Each license is decomposed into vocabularies for actions, conditions, and notices. Conditions construct logic tree with AND node, OR node, and LEAF node. This is the reason we call this data as "logically decomposed" OSS licenses.
The data is distributed in an exchange format using JSON as following files:
- licenses.json - Logically decomposed OSS Licenses which consist of actions, conditions, and notices.
- actions.json< 7735 /a> - Vocabularies for actions.
- conditions.json - Vocabularies for conditions.
- notices.json - Vocabularies for notices.
