- It would be quite useful to store only the relevant data for each day/month/year/decade/century page (e.g. 1985). That way we could implement more advanced queries, e.g. "list all important events in the years 1348-1352" and minimize the amount of stored data (saying that John Doe was born on DD/MM/YY once rather than adding his name to both the Days list, the Months list and the Years list).
Regarding the Concepts
WikiProject, I would like to understand better what qualifies as a concept and what doesn't. For instance, is "electron" a concept? How about "beauty" or "religion"? What happens if there are wpc articles about concepts which are also treated elsewhere in the Wikipedia? --
