datalink-terms

[Patrick Dowler]

Yes, I had missed out on the provenance related terms. I like the idea 
of having the generic top-level term(s) now and can add specifics later.

Normally, we think about having a link from a product back to the input, 
but it is equally valid and potentially more interesting to provide a 
link to a (better) derived product.

In that light,

#derivation describes a forward link to a product aka "is a #derivation 
from #this" +1

It's kind of a "you might be interested in this thing over here..." :-)

For the backward link to "inputs" I find #predecessor pretty vague as 
there are many sorts of sequences, not just provenance... predecessor 
also implies that the "original" has been replaced or made obsolete... 
something less specific than #input would probably be good. #precursor 
and #progenitor are ok, but a bit fancy sounding and I'm tired of going 
around thesaurus circle... anyone have a better word for this?
