We have written down our latest thinking regarding the pageview api codename Hypercube. Two recent developments:

1) We will scope down the time window that can initially be queried to somewhere in the range of 1 to 3 months. 

2) We have some outlines for an api to query the data.

Please visit https://www.mediawiki.org/wiki/Analytics/Hypercube and chime on the talk page with your comments!
