[tdwg-content] Canonical name parsing

[Dmitry Mozzherin]

I agree with Peter. Having clear disambiguation in DarwinCore between
terms for 'canonical name' and 'name with authorship' would make my
life much easier too. Right now I have to go through a quite a bit of
fuzzy logic every time I open a DarwinCore Archive file trying to
figure out what did authors of the file meant when they said
'scientificName'

I tend to agree with Donald that this would not really help in consumption, as in my experience we will have to deal with both clean and dirty data in each field *anyway* when this is used at network scale.  I would rather see us evolve the interpretation libraries to handle all the corner cases, which we need to develop anyway.  We already do a pretty decent job at extracting canonicals.  This is further enhanced when you couple the extracted canonical with a fuzzy match against the "authoritative names" we can now index thanks to the availability of checklists in DwC-A format.

We have a significant test coverage [2,3] and there have been quite some man months (years?) spent already in their development and with some real regular expression experts (most notably Markus D. and Dave M.).  All our work is Maven-ized, versioned and available in our Maven repository [4].
