Science gateways are a community-specific portals offering tools, applications, and data collections that are integrated together, providing access to data sources and services of distributed computing infrastructures (DCIs). Science gateways offer the potential to facilitate data analysis on a large scale and open the utilization of DCIs to wider audiences by providing a customized and easy to use user interface accessing large computational and data resources. The workshop aims at bringing together researchers and scientists from different scientific domains, along with science gateways developers, to discuss problems and solutions in the area, to identify new issues, to shape future directions for research, foster the exchange of ideas, standards and common requirements and push towards the wider adoption of science gateways in e-Science.
