If the person/corporate body that produced the object cannot be identified, a separate data element (in LIDO: <lido:culture>) should be used to specify the geographical, stylistic or cultural attribution of the object, if possible.
CARE: Knowledge gaps in the object's history should always be disclosed (e.g. by stating “not documented” or “not known to us” in the data elements “Person/entity”, “Date”, “Location”). Uncertainties or attributions that originate, for example, from the surviving collection entry documentation should be contextualized in a separate data element “Event description” (in LIDO: <lido:eventDescriptionSet>/<descriptiveNoteValue>). If the persons/corporate bodies involved can be researched and identified retrospectively, but do not have a unique identifier in the Integrated Authority File, collaborative knowledge databases such as Wikidata are suitable for generating unique identifiers.
