4. Apache Airavata
• Science Gateway software framework to:
– compose, manage, execute, and monitor
computational workflows
– web service abstractions to legacy command line
scientific applications
– support for computational resources ranging from
local resources to computational grids and clouds
– modular software framework to use as individual
components or as an integrates solution.

6. Interoperable Workflow Architecture

7. Apache Rave: Open Community Software for Social Networking,
Shareable Web Components, and Science Gateways
• Rave is an Apache Software Foundation incubator
project.
• Software for managing OpenSocial Gadgets and W3C Widgets
• Founding members:
• Mitre Software
• SURFnet
• Hippo Software
• Indiana University
• More information
• Project Website: http://incubator.apache.org/rave/
• Mailing List: rave-dev@incubator.apache.org

8. What is Rave?
• Rave is a downloadable Web portal
• Written in Java, JavaScript
• Based on Spring MVC framework
• Builds on Apache OpenSocial spec for social networking Web
gadgets, REST services
• Rave is a development platform
• Developers program to Rave APIs and implementations as
JARS, WAR overlays
• Developers can change, extend, or exclude only the code
without touching the source tree
• “Sandbox” examples.

9. The Apache Way and Gateways
• Apache places community above code
– Open source isn’t enough
– You need a diverse community of developers and inter-project
collaboration
• Governance
– Apache incubators are mentored to teach good project management
practices
– Source code management, public mailing lists, open decision
making, peer-reviewed formal releases
• Sustainability
– Apache incubators must demonstrate developer diversity
– Count diversity of contributors, not downloads.
– Reward projects for collaborating with each other.
