We should add a standard comment block to each Benchmark to detail exactly how it publishes data.

Today we have a schema does that is not broadly shared, and reading the code to figure of the metrics published is slow.

We should create a comment block in each benchmark file detailing how it publishes. In particular we should detail:
test - this is the name of the bechmark
owner - who is running the numbers
labels - This data is a '|' separate list of extra meta data to understand the data point. There are some common labels like 'zone' and 'machine_type'. We should detail all of them for the given benchmark.
metric - What is being reported
units - Units of the metric. There is a pretty standard list here we should not expand unless really needed.
value - the number being reported.
