Mawathage Sanjaya Priyadarshana Medonsa commented on AIRAVATA-342:
------------------------------------------------------------------
Primary ingredient to successful provenance aware workflow execution is the
rich set of Metadata captured in OODT Metadata catalog. I'd like to know the
set of Metadata that should be captured as part of the output ingestion of the
Airavata-OODT integration. These Metadata should able to provenance aware
capabilities in Apache Airavata.
I am planning to store following Metadata together with output file staged at
the OODT File manager repository.
1. FileName
2. Execution time
3. Experiment ID
4. Wokflow Instance ID
5. Node ID
I guess input value/type should also be required. Please let me other Metadata
that should be captured to improve provenance aware workflow processing.

> 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.
