Abstract

This project was developed to create a platform for implementing the features and query support provided by the transaction time axis (tt-axis). The basis for this platform is a new numbering plan called item version timestamp level numbering (IVTLN), and it extends an existing numbering plan, namely, dewey level numbering (DLN), by including version and timestamp information. Thus, the transaction time axis provides a temporal perspective for XML nodes in addition to non-temporal axes like the ancestor and descendant axes. This project provides an efficient, extensible, and comprehensible platform for the implementation of the new numbering plan and the services provided by the transaction time axis.
