Sets must be possible over multiple fields

[mpbraendle]

It should be possible to define a single set over multiple fields of the same type:

E.g.

$c->{irstats2}->{sets} = [
{
'name' => 'authors',
'field' => [ 'creators', 'editors' ]
}
];

You could define a new automatic field to merge the creators and editors, then define the irstats2 set over this new field.

Thanks Jiadi. I was thinking of a virtual field, but automatic seems to be better. As far as I understand, automatic fields are filled upon modification, aren't they? That would require to recalculate them for already existing eprints.
You can close the issue.

Yes, they are.
You can re-calculate all automatic fields by:
epadmin recommit repository_id dataset_id [eprint_id eprint_id ...]
Recommit all the records in the given dataset. What this does is
cause the automatic values to be re-calculated. If a list of
eprint_ids is given then just recommit those.
