1. Data Provenance

2. Data Provenance Goals Replicate (re-apply) analyses Facilitate comparisons across workflows

3. Data Provenance… (The Trees) Regression testing Versioning of software –Package versus individual component Need a common method for extracting information –Review of current methods developed –Need updated specification (XML) Assistance from third party developers –NIFTI?

4. Data Provenance… (The Forest) Current specifications for capturing provenance information are being developed Finalize provenance specification as part of XCEDE XML effort –How to support branching and merging in workflows Common API and services for data provenance information

5. The People in the Forest Formed cross test bed data provenance specification update (DPSU) and workflow provenance integration (WPI) working group: –Nicole (morph, chair for DPSU) –Dan, Anthony (morph) –Jeff, Neil (CC) –Syam, Randy, Dingying (function) –Hans (Brians2) –Anthony (LDDMM) –Mike Mendes (workflows, chair for WPI) –Arash (mouse/Loni)
