Bubbleupnp's work display behavior - suitable minimserver tagging

[ruckmann]

Bubbleupnp increasingly displays "work" data when accessing music albums provided online by qobuz (cf. picture attached) und uses the musical work data as headline when displaying movements of a musical work. I tried to achieve the same Bubbleupnp behavior displaying classical albums sent provided with minimsever. My classical music collection uses a tag "work" for compositions and "title for composition parts, but Buppleupnp does not show any "work" when displaying albums oder applying "show metadata". Is anybody able to tell me, which tagging might be suitable for minimserver to display work data just like qobuz?
