Format

I propose to use underscores instead of spaces in the identifier. With underscores we have definitely a working link, otherwise we need to rely on gadgets. Also other properties linking to a wiki are using underscores, e.g. Theaterlexikon der Schweiz ID (P1362) --Pasleim (talk) 16:53, 14 October 2016 (UTC)

As there hasn't been any opposition, I have now changed the format. --Pasleim (talk) 01:57, 12 November 2016 (UTC)

موسیقایی

درود. لطفاً «موسیقیایی» را به «موسیقایی» اصلاح بفرمایید. «موسیقیایی» نادرست است. با سپاس، Hamid Hassani (talk) 10:20, 3 August 2018 (UTC)

publishers

Can someone emend this property to include music publishers? (Both Q1917775 and Q222836). IMSLP has a great deal of information on music publishers (especially obscure ones) that one can not find in other sources. - Kosboot (talk) 02:28, 6 November 2020 (UTC)
