Hi everyone,
The Analytics team has just posted an initial proposal for two metadata schema's: one for general purpose webrequests and one for eventdata requests. You can find the proposed schema's at: http://www.mediawiki.org/wiki/Analytics/Kraken/Metadata_Schemas
Please add comments, ask questions, etc at http://www.mediawiki.org/wiki/Talk:Analytics/Kraken/Metadata_Schemas
Best,
Diederik
