PRACE. This concept of hiding workflows by user-oriented portlets was easily
implementable thanks to the ASM concept of WS-PGRADE/gUSE.

17.4.2 Further Development of the DRIHM Gateway

The DRIHM science gateway is under development at the time of writing this topic.
Some model-speci

c portlets have to be completed, and several aspects have to be
properly addressed due to the complex and heterogeneous nature of the considered
e-infrastructure. Regarding future development, the most important directions are
related to some planned features of gUSE/WS-PGRADE. The first one is related to

providing data provenance information for the results of the experiments. The pos-
sibility to specify in detail how a result was achieved is of particular importance. In a
future versions gUSE/WS-PGRADE will be interfaced with the Provenance manager
(PROV-man) framework in order tomake these data available (Benabdelkader 2011).
The second one is related to the activities carried out within a related project,
Distributed Research Infrastructure for Hydro-Meteorology to United States of
America (DRIHM2US, http://www.drihm2us.eu ) is an international cooperation
