    25 where x y z t are the spatiotemporal coordinates, [] indicate optional coordinates, i is the subscript identifying the instance of the feature type, while o and p are subscripts of the data values that compose that instance.  For example, each in a collection of timeSeries features, each timeSeries instance ''i'' has data values at each ''o'' time index.

    2727The aim of this chapter is to provide efficient ways of storing many instances of a given feature type in each data variable. There may be more than one data variable in the file, but in this version of CF the data variables must all be of the same feature type. Future versions of CF may generalize this to allow multiple feature types in a file.
