Open platformFrom Wikipedia, the free encyclopedia

In computing, an open platform describes a software system which is based on open standards, such as published and fully documented external application programming interfaces (API) that allow using the software to function in other ways than the original programmer intended, without requiring modification of the source code.

Open Platform의 특징

● 표준 준수, 확장성 보장, 신뢰 확보가 최우선 과제

● 개발자 –다른 서비스 제공자가 제공한지 못하던 기능이나 사용자 경험을 직접 만들어 제공 가능한 플랫폼

● 사용자 – 타인이 만든 어플리케이션을 합법적인 방법으로 사용하고 개선 가능한 플랫폼

● 결과적으로 동일한 플랫폼안에 더 많은 사용량과 열정, 시간등의 자원을 투입 가능하게함.
