[provenance-challenge] Re: clarifying queries

[Joe Futrelle]

Not sure OPM structure is enough by itself to identify corresponding nodes across traces of the "same" process given that OPM admits various levels of granularity, specificity, etc.

The challenge definition could have specified some annotations that each team was supposed to produce and then we could use descriptions like "the process whose X property has the value Y" as in PC1.
