4 Provenance – Introduction *T.cruzi Semantic Problem Solving Environment Project, Courtesy of D.B. Weatherly and Flora Logan, Tarleton Lab, University of GeorgiaT.cruzi Semantic Problem Solving Environment Project Sequence Extraction Plasmid Construction Transfection Drug Selection Cell Cloning Gene Name 3‘ & 5’ Region Knockout Construct Plasmid Drug Resistant Plasmid Transfected Sample Selected Sample Cloned Sample T.Cruzi sample Cloned Sample Gene Name ? Gene Knockout and Strain Creation * Provenance from the French word “provenir” describes the lineage or history of a data entity For Verification and Validation of Data Integrity, Process Quality, and Trust Application of Provenance Metadata beyond verification and validation – eScience Data Management 4

8 Outline Provenance – Introduction Provenance Representation Classification of Provenance Queries & Query Operators Provenance Query Engine T.cruzi SPSE Provenance Management System 8

9 Provenance Query Classification Classified Provenance Queries into Three Categories Type 1: Querying for Provenance Metadata o Example: Which gene was used create the cloned sample with ID = 65? Type 2: Querying for Specific Data Set o Example: Find all knockout construct plasmids created by researcher Michelle using “Hygromycin” drug resistant plasmid between April 25, 2008 and August 15, 2008 Type 3: Operations on Provenance Metadata o Example: Were the two cloned samples 65 and 46 prepared under similar conditions – compare the associated provenance information 9

10 Provenance Query Operators Four Query Operators – based on Query Classification provenance () – Closure operation, returns the complete set of provenance metadata for input data entity provenance_context() - Given set of constraints defined on provenance, retrieves datasets that satisfy constraints provenance_compare () - adapt the RDF graph equivalence definition provenance_merge () - Two sets of provenance information are combined using the RDF graph merge 10

11 Outline Provenance – Introduction Provenance Representation Classification of Provenance Queries & Query Operators Provenance Query Engine T.cruzi SPSE Provenance Management System 11

12 Provenance Query Engine Support Provenance Query Operators over a RDF store Provenance Query Engine based on Jena plug-in for Oracle RDF store (support for SPARQL specification) Developed as an API, compatible with any RDF store with support for Rules Maps Query Operators to Domain-specific Provenance ontology – uses RDFS Entailment Rules Query Optimization: Defined a new class of materialized views called Materialized Provenance Views (MPV) MPV defined by Provenir ontology 12
