               be composed of one or more physical pieces
               (files) which are considered inseparable.
               For example, a data storage format that maintains
               metadata and binary data in separate, but
               tightly coupled files. Granules should not
               be used to group files that have simple relationships
               or which are associated through a parent resource.
               For example, each file containing a time interval
               data for a Numerical Data resource would each
               be considered a Granule. The ParentID of a
               Granule resource must be a NumericalData resource.
               The attributes of a Granule supersede the
               corresponding attributes in the NumericalData
               resource.

                     A description of the standardized measurement

                     The description is represented as a mathematical
                     phrase. Units should be represented by widely
                     accepted representation. For example, units
                     should conform to the International System
                     of Units (SI) which is maintained by BIPM

                     or use tokens like "Re" to represent units
                     of the Radius of the Earth. Within a phrase
                     the circumflex (^) is used to indicate a power,
                     a star (*) is used to indicate multiplication
                     and a slash (/) division. When symbols are
                     not separated by a mathematical operator,
                     multiplication is assumed. Symbols for base
