displayRole versus displayFormat

[antonmb]

This is from the users guide:
“MinimServer supports customization of tag values using the option settings described in the following sections. To support customization, MinimServer gives each tag an index value, a sort value and a display value. The index value is the value shown in index lists while browsing your library, the sort value is the value used for sorting index lists, and the display value is the value shown in the control point's playlist and on the Now Playing screen.”

My understanding is - take it with a grain of salt, I’ve been known to be quite wrong - that the displayrole links a tag to a particular control point field. For example, control points typically don’t have a “composer” field in their display, so the expression composer.displayrole={artist} tells the control point to show the composer tag in its artist field. So for instance I have composer, conductor, orchestra, chorus, and soloists tags all linked to the artist field with this setting.

The tagformat, on the other hand, tells the control point how to display the information in the field. So if you have set composer.displayrole={artist} and conductor.displayrole={artist}, the tagformat setting tells the control point how to display the artist, composer and conductor in the artist field, e.g. in what order, what separators to use, etc.
