IMSLP Forums

I note in composer templates there's a place for VIAF identifying numbers. Wouldn't it be helpful if the same can be done for publishers? (I know this is a big request; some publishers are individuals, some publishers are firms, and some are both.) Note that I'm not asking IMSLP to supply the numbers, only the "template" (or similar space) where each publisher can have such an identifier. (We the users will supply the numbers.)

We have a VIAF template {{Viaf|######}}, which I suppose would work for publishers.
