PGRADE/gUSE supports this concept. It provides a full-scale user interface for
work ow developers (called power users) that enables the fast and ef cient

development of DCI-oriented work ows. On the other hand, its end-user interface

concept enables the automatic creation of an end-user interface with limited
functionality that can be easily used by scientists who do not know the underlying
DCIs. This aspect of the WS-PGRADE/gUSE gateway framework is described in a
more detailed way in Chaps. 2 and 8 .

1.5 The SCI-BUS Project

As written in Sect. 1.1 , the recommended way to develop SG instances is the
customization methodology. This approach is followed by the SCI-BUS (Science
Gateway Based User Support, https://www.sci-bus.eu ) EU FP7 project that
develops the WS-PGRADE/gUSE SG framework and also a customization tech-
nology by which a large number of scienti c user communities can easily adapt the

framework and develop their SG instance. The structure of the project and the
related applied technologies are shown in Fig. 1.1 .
