The DES software, implemented entirely by Authors at the Institute for Earth Observation at EURAC Research (former Institute for Applied Remote Sensing), is a standalone application to enable the execution of tasks and data transfers from and to different systems by means of a set of XML processor configuration files. It has been primarily developed to fit the requirements of the EURAC receiving station processing chain and SDI Infrastructure here at EURAC Research where big amounts of data need to be processed and transferred from system to system or delivered to some end users. The DES implements a concurrent, multi-threaded mechanism to transfer different kind of data in PUSH and GET mode using standard protocols like HTTP, SFTP, FTP, SSH. However, the DES may be seen as a general, multi-tasking application that can execute concurrently configurable tasks or jobs implemented in dedicated plug-ins or scripts. The basic concept behind the DES is that data is organized in a hierarchical basic structure that reflects a $AOI/$PROCESSOR scheme and that Events or Tasks are triggered by files filtered with regular expressions.
