Fig. 9.3 Researcher (or browse) view of the SHIWA Workflow Repository, containing
description and metadata about the abstract workflow ( left ) and two implementations ( right )
upload workflows from the WS-PGRADE/gUSE science gateway using the export
operation. In the second case they enter workflow data manually using the developer
(or table) view. The repository offers two major operations to
find workflows:
browse and search operations. The browse operation enables checking the list of
workflows, selecting them, and displaying their details. The search operation allows
users to specify search criteria, for example, domain name or workflow name to
filter
the search operation. Users can browse and/or search the repository in both the
researcher (or browse) and developer (or table) view, and select workflows they want
to execute. They can access the repository through either the repository GUI or the
repository portlet of the WS-PGRADE/gUSE science gateway. In the third scenario
users can automatically or manually download workflows from the repository. The
WS-PGRADE/gUSE science gateway enables users to automatically import work-
flows from the repository. Workflow developers can also manually download
workflows through the developer (or table) view.
