_State here which combinations of teams' models you have managed to perform the provenance query over_
_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_
_Describe your proposed benchmark queries, how the comparable quantities are determined, and the results of applying the benchmark to your own system_
