Dublin Core

Dublin Core is a flat schema: elements without nesting. Moliri outputs the elements in the usual dc: and dcterms: form.

The effort is small, because every element points to a concept and the mapping is shared with LIDO . If you have mapped for the minimum data set, most of the work for Dublin Core is already done.

Elements

What follows from this

dc:date is the date of the object, not that of the record. It points to productionDate, the date for display. A text such as c. 1900 is permitted and correct here.

dc:creator points to creator, not to a person from an event. If you record authorship through events , you also need a mapping for creator, usually a display field or an authority field.

dc:coverage combines spatial and temporal coverage. In LIDO these are separate nodes. Moliri maps it to productionPlace.

There are no facets. Where LIDO outputs a structured concept, Dublin Core outputs text. For an event this means: the display form, not the structure.

There is no binding schema for Dublin Core. The schema validation (XSD) before export is therefore skipped.

When Dublin Core fits

Dublin Core is the lowest common denominator: understood everywhere, brief everywhere. For collection data, LIDO is the appropriate format. Dublin Core is the choice where the other side accepts nothing else.
