3-way merging for XML in XML Europe paper
We promised in the last (May) newsletter to provide some more news about this paper - you can download it from http://www.deltaxml.com/pdf/merging-xml-files.pdf
The paper was presented in the Technical stream at XML Europe 2002 in Barcelona 21-23 May 2002. It discusses both 2-way merging - when there are just two files to merge - and the more powerful 3-way merging. Merging three XML files provides a way to merge the 'edits' between a base and two different files.
There are many uses for this including synchronization of XML data, maintaining variants of a base file (you can automatically update the variants when the base is changed), and merging the results of concurrent editing of documents. Have you ever been in the situation where you've done lots of work on a file ... and then the file is updated! So use DeltaXML 3-way merge to avoid doing those edits all over again! Expected soon - more news in next newsletter.
INRIA paper updated
We told you about this last time - the paper has been updated since then. Based on an analysis of 40,000 XML files found on the web, the French research group INRIA, key sponsors of W3C, have produced a paper assessing the functionality and performance of various XML software comparison tools.
Their conclusions include this statement, "DeltaXML seems the best choice because it runs extremely fast and its results are close to the minimum."
