> We needs an implementation of JSR-363 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.

(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.
