Did you check the workflow tracking schema [1]? it has a decent description of the schema. Ideally speaking, every execution event should at the minimum have a experiment id, workflow id. Also, please read the following papers which will explain you the schema for events in a detailed way [2] , [3]. > > Also Can we have sample notification messages for a experiment which has > multiple workflows ? I do not think Airavata has hierarchal workflow samples. One way to obtain that is to change your question and ask the dev's nicely :) a questions can be something like ...I will create an experiment with hierarchal workflows (a meta workflow with sub workflows) Can any one help me do that? ..a answer will be something like ..please goahead and do it, if you run into issues, raise a JIRA and we will help you fix it and submit a patch :) Cheers, Suresh [1] - https://svn.apache.org/repos/asf/incubator/airavata/trunk/modules/commons/workflow-tracking/src/main/resources/schemas/workflow_tracking_types.xsd [2] - http://gridtestbed.org/sites/default/files/SimmhanICWS06.pdf [3] - http://www.ptl.iu.edu/sites/default/files/Simmhan-JWSR-07.pdf > > Thank You, > Hasitha. > > On Tue, Jun 5, 2012 at 10:41 AM, Suresh Marru <[email protected]> wrote: > >> Hi Hasitha, >> >> All three of these are for different purposes. >> >> An experiment corresponds to an "experiment" or "investigation" done by a >> scientist/user and might require multiple workflows (in a hierarchal >> fashion) to accomplish it.
