The consistency control system of XML documents

As XML documents become widely used, demands for concurrent authoring of XML documents increase significantly CVS is widely used for traditional plain-text based documents, but it doesn't meet the demands sufficiently This is because CVS is based on line-oriented diff and merge operations, and doesn't pay attention to XML tree structure. To cope with this problem, we developed a topology-sensitive XML diff algorithm. The consistency control system based on our algorithm can handle XML tree structure appropriately, reduces unexpected conflicts, and generates properly merged outputs.
