Abstract: The present invention concerns an appliance, a process and a computer programme product for the processing of unstructured or semi-structured digital data in a file system. In order to create an appliance, a process and a computer programme product which allow simple, reliable, highperformance and purpose oriented management of every manner of digital, stored, unstructured data, it is proposed that, it is functionally extended by providing a framework for further external logic to be inserted in order to modify the filesystem's behaviour and/or a structure is imposed onto unstructured or semi-structured data in real time by enhancing existing namespace semantics and/or metadata and data are processed independently by physically and logically separating namespace and block handlers.
