During the push of bug 8976 we discovered some inconsistencies in Koha::Object class names which lead to duplication. We need to clarify the situation and move classes around to be consistent. Current situation: Koha::Authority::Subfield(s) Koha::Authority::Tag(s) Koha::Authority::Type(s) Koha::Biblio::Metadata(s) Koha::MarcSubfieldStructure(s) Koha::AuthSubfieldStructure(s) In bug 8976 we made a few suggestions Koha::Framework::Biblio::Subfield(s) Koha::Framework::Authority::Subfield(s) Koha::Framework::Biblio::Tag(s) Koha::Framework::Authority::Tag(s) OR Koha::MARC::Biblio::Subfield(s) Koha::MARC::Authority::Subfield(s) OR Koha::Framework::Subfield::Biblio (inheriting from Koha::Framework::Subfield) Koha::Framework::Subfield::Authority (inheriting from Koha::Framework::Subfield) Thougts?
