안녕하세요.

해외사이트에서  폰트를 다운받았으며,  폰트와 OFL 라이센스 텍스트 파일이 함께 받아졌습니다.

질문 1

폰트를 수정(형태변형, 일부분삭제) 등이 가능한가요?

질문 2

해당폰트를 활용. [OOO소싱 사이트에서 심볼과 로고디자인을 하여 수익을 창출 할 예정입니다. OFL라이센스 폰트로 이사이트에서 수상하여 수익을 발생하는 행위가 가능한가요?

(물론, 인터넷, 유튜브, 종이인쇄 등으로 노출이 될 수도 있습니다.) (폰트자체를 판매하지는 않습니다.)

질문 3 

OFL 라이센스가 있는 폰트는 유효기간이 정해져 있나요?

예를 들어, OFL 라이센스로 되어 있지만,  제작자가 OFL라이센스를 취소하고, 유료로 변경할 수 있는것인가요.

아니면, 한번 OFL라이센스로 되어 있으면, 기간한정없이 계속 무제한으로 OFL 라이센스로 유지를 하는 것인가요?

질문 4

해외사이트에서 다운받은 폰트가 몇개 되는데요.

그 중 폰트 명이 'Prata-Regular' , P'rata'로 되어 있어서 OFL 라이센스인지 확인하려고 하는데 검색을 어디에서 하는지 찾지를 못하였습니다.  검색사이트 주소를 알수 있을까요? 

이상이며, 많이 바쁘시더라도, 빠르고 명쾌한 답변부탁드립니다.

감사합니다.

아래는 폰트를 다운받을때 포함되어 있던 OFL텍스트 파일의 전문입니다.
