The Keridwen's Hierarchised Data Model is organised around a modular tree structure that can be adapted to the specific needs of each application field. The various data are linked to each node. Each node is directly in charge of the reading/writing of its own linked data. Thanks to this modular approach, it can be easily extended to various domains of application.

Data are then stored into a self-consistent and robust workspace, gathering all tailored data organised into structured sub-directories.

A lazy loading/writing mechanism allows to load and write nodes progressivelly and on-demand in order to optimise the disk access, on one hand, and maintaining the cross-consistency between the memory and disk images.

Key Features
