We are still waiting on the CMS to be setup so we can get the documentation and discussion
on the list. We can start with a high level architecture diagram and start drilling into components.
The main goal is to make sure we all are on the same page with the Airavata code. Meanwhile
we should also have the logo and web page so we can start marching.

same time I realize not every one of us on the list have a full understanding of the architecture
as a whole and sub-components. Along with inheriting the code donation, I suggest we focus
on bringing every one to speed by means of high level and low level architecture diagrams.
I will start a detailed email thread about this task. In short, currently the software assumes
understanding of e-Science in general and some details of Grid Computing. Our first focus
should be to bring the software to a level any java developer can understand and contribute.
Next the focus can be to make it easy for novice users.

on the first goal with detailed JIRA tasks. I am assuming you will steer us with a orthogonal
roadmap to graduation. I hope I am not implying we need to meet the following goals to graduate,
because some of them are very open ended. Also, please note that Airavata may have some of
these features already, I am mainly categorizing so we will have a focused effort in testing,
re-writing or new implementations.

workflow enactment engine will be the inherent Airavata Workflow Interpreter. Register command
line applications as web services, construct and execute workflows with these application
services. The applications may run locally, on Grid enabled resources or by ssh'ing to a remote
resource. The client to test this phase workflows can be Airavata Workflow Client (XBaya)
running as a desktop application.

BPEL. Develop and deploy gadget interfaces to Apache Rave container to support application
registration, workflow submission and monitoring components. Support applications running
on virtual machine images to be deployed to Amazon EC2, EUCALYPTUS and similar infrastructure-as-a-service
cloud deployments.

Focus on the data and metadata catalog integration like Apache OODT.

phase 1 goals, I will start a detailed discussion on where the code is now and the steps to
get to goal1.
