Taxonomy user manual
Taxonomy allows to create controlled vocabularies within Omeka S.
Controlled vocabularies (taxonomies) and controlled vocabulary terms (taxonomy terms) are Omeka S resources, which means:
they can be linked to items, item sets and media like any other Omeka S resources (they can be linked in annotations too);
they can be described like any other resources (resource template, class, properties, annotations);
they can have a thumbnail.
Taxonomy terms can be arranged in a hierarchy (a taxonomy term can have a parent term).
