also has access to external gLite resources by submitting jobs authenticated with robot
certi
cates, or to invoke third-party REST services.
On other hand, more complex workflows with more data processing jobs are
expected in the agINFRA project, which would further improve the quality of the
harvested datasets.
The elaborated workflows and related solutions will be exploited and developed
further in the recently launched AgroDat.hu project between 2014 and 2018. Its
main aim is establishing a new Hungarian knowledge center and decision support
system in agriculture-based on collected sensor data and international aggregated
databases.
17.3 The VERCE Science Gateway: Enabling
User-Friendly, Data-Intensive and HPC
Applications Across European E-Infrastructures
Seismology addresses fundamental problems in understanding earthquake dynam-
ics, seismic wave propagation, and the properties of the Earth
'
s subsurface at a large
number of scales. These aim at aiding society in the forecasting and mitigation of
natural hazards, energy resources, environmental changes, and national security.
The Virtual Earthquake and seismology Research Community in Europe e-science
environment (VERCE) is supporting this effort by developing a service-oriented
architecture and a data-intensive platform delivering services, workflow tools, and
software as a service, integrating access to the distributed European public data and
computing e-infrastructures (GRID, HPC, and CLOUD) within the VERCE science
gateway.
The development of a scienti
c gateway is a very complex task. It requires
several standard components, which are fundamental to connect and exploit
existing computational infrastructures, such as the European Grid Infrastructure
(EGI)

or PRACE.

These components are typically related to job-submission
management, user authentication, pro
ling, credential management, data manage-
ment, and application registries. An effective science gateway needs to present a
consistent integration of data, metadata, application code and methods oriented to
the needs of its scienti
cient
for experienced users. It should encourage or enforce the governance rules and
mores that its community wishes to establish. Therefore, support for standards and
customization is necessary in order to produce a dedicated gateway that is tailored
for a speci
c users. It needs to be easy to use for new users and ef
c community. In this section we illustrate the rationale behind the
adoption of WS-PGRADE/gUSE in relation to those requirements.
