허용형SPDX 식별자:
Apache-2.0OSI ✓데이터 갱신일: 2026년 9월 26일기계 번역쉬운 설명
명시적인 특허 허락과 특허 보복 조항이 있고, 수정한 파일을 표시하도록 요구하는 허용형 라이선스입니다.
비유: 특허로 소송하지 않겠다는 약속이 붙은 무료 도구 상자. 단, 당신이 먼저 소송하면 그렇지 않습니다.
장점
- + 모든 기여자의 명시적 특허 허락
- + 많은 기업과 재단이 선호
- + 상표를 보호
단점
- - 길고 NOTICE 파일 처리가 필요
- - GPL-2.0-only와 비호환
- - 호스팅형 경쟁자는 막지 못함
