Is the repository used by just the one RDM Project?
If no, then their eprintids will be interspersed with other projects
Do they understand that eprintids are assigned when a new item is
STARTED... so it that item doesn't complete, or get reviewed, there will
be a gap between the prior and following [shown] records
There will be no *easy* way to do it.... it's basically assumed to be an
auto-increment field - though I've not looked at the code that gets the
next available ID to see:
a) if it's a single core routine, or
b) how easy it would be to hack so it does some kind of lookup
..... but I raise the question "How will you find the first free hole?"
you'll either need to poke every eprintid from 1 until you find a hole,
or do yet more hacking to somehow keep a track of ids that are made free
