 ref - Quandl reference object GetIdentifier

 • returns the identifier by which the data set can be found, as assigned by Quandl, as a string. It consists of an alphanumeric code for the data source where Quandl gets the data, followed by a forward slash, and then another alphanumeric code. GetFromDate, GetToDate

 • return date strings that represent the starting or ending date for the data that the object represents. They are accepted by StringTools[ParseTime] when used with the format "%Y-%m-%d". For example, "2015-02-18". GetName

 • returns a human-readable name for the data set, as a string. This is normally half a line long. GetDescription

 • returns a longer human-readable description for the data set, as a string. This is typically one or a few paragraphs long. GetFrequency

 • returns one of the names daily, weekly, monthly, quarterly, and annual. It gives the frequency of the data that the object represents. Not all data points for the given frequency between the starting and ending date are necessarily present. • returns a list of the column names, as strings. Examples
