[GSoC] Integrate Airavata Workflow Interpreter with OODT to improvise
provenance aware workflow execution
---------------------------------------------------------------------------------------------------------
Key: AIRAVATA-342
URL: https://issues.apache.org/jira/browse/AIRAVATA-342
Project: Airavata
Issue Type: Sub-task
Components: Workflow Interpreter
Reporter: Suresh Marru
Fix For: WISHLIST
Airavata workflow interpreter provides features of provenance aware workflow
execution. In a over simplified case If a workflow has 10 components, and if
5th component output is already in there in the registry, then workflow
dynamically adapts the graphs and jumps to executes from 6th component. This
feature needs the output matching to be semantically correct. Rich metdata
expression about outputs and an efficient data cataloging and querying will
enhance this capability significantly.
The proposed new feature is to utilize OODT to register, query and adapt the
workflow execution based on the enhanced metadata extraction and cataloging.
Airavata & OODT developer communities will be able guide in implementing this
task.
