We have collected birth and death dates for many of the Chilean artists that belong to our databases. Most of this data comes from musicapopular.cl. However, this data doesn’t have any formatting rules and it seems that different people entered data with different criteria. In other words, there are different styles of spanish dates.
As MB supports fields for date periods in the form YYYY-MM-DD, we developed a script using regular expression to parse all dates to this format. Done.
