Developers often copy code for parts or entire products to start a new product or a new release. In order to understand the software change history and to determine the code authorship, we propose to construct a universal version history from multiple ...
A method for controlling versions of software and other hierarchically structured entities is presented. Using the variant structure principle, a particular version of an entire system is formed by combining the most relevant existing versions of the ...
Office applications such as OpenOffice and Microsoft Office are widely used to edit the majority of today's business documents: office documents. Usually, version control systems consider office documents as binary objects, thus severely hindering ...

Version control in data systems containing sequential files of objects is the subject of this paper. The authors present algorithms for reconstructing the versions of a file using a complete version and successively modifying this data structure by applying a sequence of differential files called version control s ystem files. Efficient version control is important in software development, temporal databases, computer-aided design, and document production systems. The presented method for reconstruction of a version has time complexity that is linear in terms of the size of the complete version and the total size of the differences between the sequence of versions directly required for the reconstruction. This size is a significant improvement over such systems as the RCS version control system and is comparable to most differential file generation schemes.
