EMBOSS Provenance Example

An e-scientist looks at a value within the myGrid information repository (MIR) and wonders:

• Where did this come from? (Do I really trust this data?)

If the same workflow was run at different times, the results may differ. For example, EmbossProvenanceExampleResults

Example result

For example I look at the value

Example provenance

The metadata for this value includes a workflow provenance record.

This indentifies:

• workflow instance id - the workflow that created this value
• user - the user who ran the workflow ProvenanceExampleUser
• input data - the input given to the workflow ProvenanceExampleInput
• time - when the workflow was run ProvenanceExampleWhen
• services - what happened when the workflow was run ProvenanceExampleServices

Not included

• workflow definition - the workflow source in WSFL that was given to the enactment engine.
• service metadata - the provenance record has details of the invocation of a service from the prespective of the enactment engine, but it does not have any metadata that might be available from the service itself.
• why - any additional annotation that the user who ran the workflow might want to include, for example
