We should call that the ‘formal specification’ then. Hm, a UDF that does this rather than a Hive query would probably be better. E.g.

This is the highest level filter, and exists primarily to distinguish requests worthy of further evaluation. Our plan is to take the definition as it exists on the 12th, and begin generating high-level aggregate numbers based on it. In future iterations, we will be digging into different breakdowns of this metric, and iterating on it to handle any inconsistencies or unexpected results. There's a few differences from Web Stat Collector's (WSC) version of the general filter that we want to call to your attention to. >>> We include searches -- WSC explicitly excludes them. >>> We include Apps traffic -- WSC does not detect Apps traffic >>> We include variants of /wiki/ (e.g. /zh-tw/, /zh-cn/, /sr-ec/) -- WSC hardcodes "/wiki/" >>> We don't include Banner impressions -- WSC includes them. >>> There are also some known issues with the new definition that are worth your notice: >>> >>> Internal traffic is counted >>> Note that WSC filters some internal traffic by hardcoding a set of IPs in the definition. We are working on parsing puppet templates in order to automatically detect which IPs represent internal traffic. This will be a /better/ solution, but it's not quite ready yet because parsing puppet is hard. >>> Spider traffic is counted >>> We will be using the User-agent field to detect and flag spider-based traffic. This "tag definition" will be delivered in a subsequent definition. This actually matches WSC, which does not filter spider for the high-level metrics. >>> These are problems we're aware of, and will be factoring in as we go forward with our next task: refining the definition using real, hourly-level traffic data.
