I have installed this module and I assume that this works not only in the regular content type but also in the group module. I was expecting that after enabling the module there is an option to map my group type fields in the manage fields section but none even in the edit setting of the group type.
Notice this from the module:
RDF UI Map Content Types to Schema.org Types. Map Fields to Schema.org properties.
Does the group module supports schema integration? If yes, is there any documentation provided?
