OpenTag License Information

About the OpenTag License Version 1.0
The OpenTag License Version 1.0 is an open source license, with similarities to the BSD license, but with explicit terms related to licensing of intellectual property. The OpenTag License Version 1.0 also draws from certain elements of the Apache License Version 2.0.
- Permissive, with no copyleft or linking restrictions (like BSD)
- Requires RAND licensing of associated intellectual property, if any exists
As of 2012, legal proceedings in the United States and recent legislation in the EU have lead to the precedent (or formal law) that existing open source licenses do not guarantee royalty-free usage in the presence of related intellectual property. The OpenTag License explicitly applies said US and EU rulings to its worldwide user-base, putting everyone on equal ground. Additionally, the OpenTag License stipulates that enforcement of any potential royalties must be RAND (Reasonable And Non-Discriminatory).
- Allow symmetry with ISO open standard licensing terms.
- Actively prevent monopolistic entities from “hijacking” open source projects through non-RAND royalty settlements, or (as in the case of GPL), by flooding the market with GPL'ed code for the purpose of undermining existing markets for the product.
- Encourage commercial participation in the OpenTag project, as many corporations have policies to avoid participation in projects without explicit terms related to RAND licensing of intellectual propert
