> We needs an implementation of {{org.unitsofmeasurement.Unit}} to be used as a replacement
of JSR-275. This is needed since the JSR-275 specification attempt has been rejected. Some
existing implementations exist, especially the UOMo and JScience projects, but we also have
some legacy classes that we could refactor. A possible advantage of the later approach is
that we have to support some rather particular Unit, like the one used in NetCDF files (e.g.
"degrees_east"), which may be easier in a custom implementation.
> Some useful links:

have to implement.
> * http://www.qudt.org/ - Quantities, Units, Dimensions and Data Types in OWL and XML
(ontology).
> * https://code.google.com/p/unit-ontology/ - apparently the same than above.

UoM in an OGC standard.

- a dictionary of unit symbols related to OGC standards.
> * http://unitsofmeasure.org/trac/ - UCUM, a text format for units.
