[tdwg-tag] Another reason why RDF is cool

Hi, some comments on http://semant.blogspot.com/2006/09/adding-triples-using-
editgrid.html:
A practical problem is of course the choice of predicates from a vocabulary of
millions of potential URIs. In prinicpal, that is universal, but it is relevant
if the assumption is that raw tools suffice and are easy. This reminds me a bit
of the older DELTA pioneers who simply had remembered the their characters and
state numbers (i.e. equivalent of URIs) by heart.
A more general thing that bothers me about using RDF: if I have many such
statements without knowing who made them (e.g. someone I know, someone I know
can identify this ant, someone I know cannot), perhaps when (I myself as a
student years ago or just now), and under which circumstances (including
whether from own observation or citing other sources), these data become of
doubtful value.
Dealing with this in RDF using reification mechanism seems to be a management
problem. I belief treating statements as naturally related (e.g. a chapter in a
book, a wiki page) is more natural than treating them as atomic.
