Suite à la création

@Pamputt:

1. j'ai remarqué qu'il y plus d'entrées en fr: j'ai mis les 2 langues et j'ai dû changer "source" du coup
2. tant qu'il y aura des opéras, il y aura des entrées nouvelles, donc always incomplete (Q21873886)

Je m'en vais créer les autres ;)

Merci pour les créations Eihel (étant le proposant, je ne peux pas les créer moi-même). Pour les nombres différents d'entrées en français et anglais, c'est étrange. Si je tombe sur un cas comme ça, je regarderai comment se comporte l'identifiant sur l'autre langue. Pamputt (talk) 20:37, 22 August 2020 (UTC)

@Pamputt: ah oui ! Zut ! Je vais aussi changer les RegEx, car il y a des caractères cyrillique (avec les œuvres en relation…). Les chiffres finaux me semblent être l'année. Je vous fais ça et vous me dites ce que vous en pensez? —Eihel (talk) 20:45, 22 August 2020 (UTC)

 Done @Pamputt: —Eihel (talk) 21:05, 22 August 2020 (UTC)

• Dans Opera Online composer ID (P8551), c'est le romain numéral minuscule qui pose problème (example 4) : RegEx arrangé. —Eihel (talk) 22:35, 22 August 2020 (UTC)
