Abstract Researchers want to run scienti c experiments focusing on their disci-

plines; they do not necessarily want to know how and where the experiments are
executed. Science gateways hide details by coordinating the execution of experi-
ments using different infrastructures and workflow systems. ER-flow/SHIWA and
the SCI-BUS project developed repositories to share artefacts such as applications,
portlets, workflows, etc. inside and among research communities. Sharing artefacts
in repositories enables gateway developers to reuse them when building a new
gateway and/or creating a new application.

9.1 Introduction

Researchers simply want to run scienti c experiments focusing on their disciplines.

Science gateways hide details how and where experiments are run by coordinating
the execution of experiments using different infrastructures and workflow systems.
Using a science gateway framework signi cantly speeds up the gateway develop-

ment process when compared to development from scratch. Most gateway frame-
works provide such common services as authentication, job/workflow submission
to various DCIs, monitoring and information system capabilities, or execution
statistics, just to mention a few. These services are provided by the framework itself
and are typically tightly coupled with the underlying technology.
