Hi Surresh, Currently we are working on developing Cassandra data model API as a part of First milestone plan. You can find the milestone plane at [1] and the description of the Airavata workflow's Data model at [2]. Hope we can finish the first milestone target in next two weeks.
We decided to go with the name "MetCat". But we are also pleased to have any suggestions if you have any. We need help on getting workflow notification messages from Airavata server. I will start a separate mail thread to discuss that problem. Thank You, Hasitha [1] - https://docs.google.com/document/pub?id=147JtpOn19BSDsdXKZK4gOVPn5G2qeDJTnTcIrbr9tUE<https://docs.google.com/document/d/147JtpOn19BSDsdXKZK4gOVPn5G2qeDJTnTcIrbr9tUE/edit> [2] - https://docs.google.com/document/pub?id=1GYD45QU9PXBui2P9yAUv-I8OtMi7Xp3nAjD6X-Dr6iw On Sat, May 26, 2012 at 12:53 AM, Suresh Marru <sma...@apache.org> wrote: > Hi Folks, > > Any headway into this project?
