[tdwg-content] A proposal to improve Darwin Core for invasive species data

I would say that the primary factor driving the philosophy for loose
controlled vocabulary recommendations is a desire to promote the stability
of Darwin Core term definitions, because changes can be disruptive. Section
1.4 on the Simple Darwin Core page (
http://rs.tdwg.org/dwc/terms/simple/index.htm) gives further practical
arguments for this stance. I have copied the relevant text here for
convenience:

"There is a difference between having data in a field and requiring that
field to have a value from among a legal set of values. The Darwin Core is
simple in that it has minimal restrictions on the contents of fields. The
term comments give recommendations about the use of controlled vocabularies
and how to structure content wherever appropriate. Data contributors are
encouraged to follow these recommendations as well as possible. You might
argue that having no restrictions will promote "dirty" data (data of low
quality or dubious value). Consider the simple axiom "It's not what you
have, but what you do with it that matters." If data restrictions were in
place at the fundamental level, then a record having any non-compliant data
in any of its fields could not be shared via the standard. Not only would
there be a dearth of shared data in that case (or an unused standard), but
also there would be no way to use the standard to build shared data
cleaning tools to actually improve the situation, nor to use data services
to look up alternative representations (language translations, for example)
to serve a broader audience. The rest is up to how the records will be used
- in other words, it is up to applications to enforce further restrictions
if appropriate, and it is up to the stakeholders of those applications to
decide what the restrictions will be for the purpose the application is
trying to serve."
