The Collection is an accumulation of TextGrid Objects formed by the membership of a particular organisation and/or topic. Collections are intended for two use cases: In an organizational context, an Edition may be part of a Collection (e.g. the combination of editions from the Blumenbach project under the “Blumenbach” label or the combination of digitized prints of the 18th century under the label VD 18). Additionally, Collections can be used to aggregate Items for which the Edition/Work concept is not applicable, i.e. digitizations of museum pieces. Collections are valid starting points for publication.
