This is the work area of editors who are authorised to work on concept cards, the data that make the immediate environment of concepts. They add synonyms, spelling and language variants, see-also relations, lemma descriptions, etcetera. They also accept or reject candidate concepts contributed by content metadata editors.
In daily practice the function of concept editor often overlaps with that of reference editor.
On an editorial level, authorised staff should be able to edit all data that belongs to the concepts of reference structures, the concept cards.
For instance, they must be able to add synonyms and name variants (e.g. common misspellings). They should be able to create see also relationships with other concepts, to edit closely coupled data such as naming responsibilities (taxonomic thesaurus), and to add lemma's, descriptions concerning the meaning of concepts.
Regular content editors, who create articles or compile material written by others, must be able to add concepts to a reference structure.
A two-stage model applies here.
The concept editors work in a shielded environment geared towards the management of reference structures and concepts. They will have no direct access to the infrastructure.
