use case: parse DOIs into their pieces about parseids HOT 3 OPEN

I think so. I actually don't know enough about DOI formats to know if the suffix can be broken up into further components. I guess that's specific to the publisher?

from parseids.

Prefix can be further broken up in to 10 + XXXX. the 10 at the beginning is always 10 for DOIs.

For suffixes, yeah I think germane to the publisher so not sure there's one way to parse those, there could be publisher specific parsing, but that would be a huge can of worms

from parseids.

now there's fxns for getting out prefixes and suffixes

still working on a fxn to split by separator / - easy in theory, but getting used to PEG stuff

from parseids.
