Summary: [GSoC] Web based Workflow Composer for Airavata
Key: AIRAVATA-798
URL: https://issues.apache.org/jira/browse/AIRAVATA-798
Project: Airavata
Issue Type: New Feature
Components: Workflow Interpreter, XBaya
Reporter: Suresh Marru
Apache Airavata users construct workflows by chaining together set of
applications and web services resulting in a graphical representation of
workflows. These workflows composed by drag and drop features build a abstract
and high lever workflow languages.Currently Airavata XBaya services these needs
and is implemented in Java Swing. Similarly XBaya was also implemented in Flex.
This project focuses on developing a web based version of the workflow
composition and monitoring interface similar in functionality to XBaya.
Currently XBaya WSDL operations and message type definition determines both the
number of input/output parameters that the component has and the data type of
each parameter. Messages are general XML and can have deeply-nested structures.
However, XBaya treats the child elements of the root of a message as
independent parameters. The type of each parameter can be any simple type
(string, integer, etc.), array, or a complex type. The potential student can
evaluate the use of WSDL and come up with alternatives.
The student for this task has to be prepared to work extensively in java script
to build the drag drop interface. WSDL knowledge will be preferred but not
mandatory, that can be acquired.
User community & Impact of the software: Airavata is a general purpose
distributed systems software. It is used to build science gateways supporting
research and education in chemistry, life sciences, biophysics, environmental
sciences, geosciences astronomy and nuclear physics. The goal of airavata is to
enhance productivity of these gateways to utilize cyberinfrastructure of
resources (e.g., local lab resources, the Extreme Science and Engineering
Discovery Environment (XSEDE), the Open Science Grid (OSG), University
Clusters, Academic and Commercial Computational Clouds like FutureGrid & Amazon
EC2). By using open community based software components and services like
Airavata, gateways will be able to focus on providing additional scientific
capabilities and to expanding the number of supported users. The capabilities
of these gateways will offer clear benefits to society.
