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.

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

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.

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.
