License Selection

Default: Apache-2.0

SK Telecom applies Apache-2.0 by default. As a permissive license with a patent grant, it suits projects a company releases.

When to Consider Another License

• The ecosystem favors a specific license. Following community convention eases adoption.
• There is a dependency on a copyleft library such as GPL. You may have to follow the dependency’s obligations.

Permissive vs. Copyleft

• Permissive licenses (Apache-2.0, MIT, BSD) require little more than attribution and do not force a license on derivative works.
• Copyleft licenses (GPL, LGPL, MPL) can require derivative or combined works to be released under the same terms. The scope of the obligation varies by license.

Check Dependency Compatibility

Make sure the chosen license does not conflict with the licenses of your dependencies. For example, a strong copyleft dependency can make a permissive release impossible. For per-license obligations, see the license obligations section under “Using,” and request an OSRB review if the decision is unclear.
