---++ 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._

---++ 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._
