초록

오피스 및 과학 분야의 문서 작업 등에서 XML의 사용이 보편화되고 협업이 요구됨에 따라 효과적인 XML 문서 병합 방법이 필요하다. 이에 대한 해결 방안으로 본 논문에서는 동일 원본 문서에 대한 다수 사용자의 편집 작업들의 병합을 위한 이론적 틀을 제시한다. 문서들의 병합시 문서 자체를 병합하는 기존의 방법들과는 달리, 사용자의 편집 작업을 원본 문서에 적용되는 일련의 편집 연산들, 즉 편집 스크립트로 표현하고 다수 사용자의 편집 스크립트들을 병합하고 원본 문서에 적용하여 문서의 병합 효과를 이루고자 한다. 이를 위해 삽입과 삭제연산으로 구성된 편집스크립트를 전제로 정적 편집 스크립트, 편집 스크립트의 간섭 및 충돌 등의 개념들을 정의하고 편집 스크립트들의 충돌 조건과 병합시 편집 스크립트 조정기법을 제안한다. 이 방법은 분산 환경에서 네트워크 부하를 줄이며 각 편집 작업의 의미가 보존되어 버전관리에 효과적이다.

The method of effectively merging XML documents becomes necessary, as the use of XML is popular and the collaborative editing is required in the areas such as office documents and scientific documents editing works. As a solution to this problem, in this paper we present a theoretical framework for merging individual editing works by muli-users to a same source document. Different from existing approaches which merge documents themselves when they are merged, we represent editing works with a series of edit operations applied to a source document, which is called a edit script, merge those edit scripts by multi-users, and apply the merged one to the source document so that we can achieve the same effect of merging documents. In order to do this, assuming edit scripts based on insertion and deletion edit operations, we define notions such as static edit scripts, the intervention between edit scripts and the conflict between the ones, then propose the conflict conditions between edit scripts and the method of adjusting edit scripts when merged. This approach is effective in reducing network overhead in distributed environments and also in version management systems because of preserving the semantics of individual editing works.
