University of Chicago Computation Institute

This is the 2nd Provenance Challenge page for the University of Chicago Computation Institute.

Participating Team

• Short team name: UChicago / University of Chicago Computation Institute
• Participant names:
• Project URL:
• Reference to first challenge results (if participated): UChicago

Differences from First Challenge

A later version of VDS was used (CVS as of 2007-02-20), on a different host (mac os x vs linux in the original)

Provenance Data for Workflow Parts

Give links here to your provenance data files for the workflow parts of the challenge: three parts for the original workflow and three parts for the modified workflow (as per provenance query 7). The data files could be attached to the results page.

stage 1 workflow VDC: stage1.dump

stage 2 workflow VDC: stage2.dump

stage 3 workflow VDC: stage3.dump

(for comparison, a run of the entire workflow at once: db-3.dump)

Data is provided as an SQL dump of the provenance database (the Virtual Data Catalog). We can provide an XML wrapping of this if people would prefer, but SQL is the model we use internally and so feels more genuine this way...

This dump file can be fed into PostgreSQL^? using the commands:

createdb uc

pg_restore -d uc db-3.dump

Model Integration Results

State here which combinations of teams' models you have managed to perform the provenance query over

Translation Details

Describe details regarding how data models were translated (or otherwise used to answer the query following the team's approach), any data which was absent from a downloaded model, and whether this affected the possibility of translation or successful provenance query, and any data which was excluded in translation from a downloaded model because it was extraneous

Benchmarks

Describe your proposed benchmark queries, how the comparable quantities are determined, and the results of applying the benchmark to your own system

Further Comments

Provide here further comments.

Conclusions

Provide here your conclusions on the challenge, and issues that you like to see discussed at a face to face meeting.
