Format Considerations

As of r4656, Zotero uses libraries derived from ​Tabulator to handle RDF. These libraries provide both XML and N3 serializers for RDF triples. In order to remain compatible with applications lacking RDF parsers, we will likely use RDF/XML for export.

Field Mappings

The list of base field mappings was generated by the SQLite query

SELECT GROUP_CONCAT(f1.fieldName, '[[BR]]') FROM fields AS f1
LEFT JOIN baseFieldMappings AS b ON (b.fieldID = f1.fieldID)
LEFT JOIN fields AS f2 ON (f2.fieldID = b.baseFieldID)
GROUP BY IFNULL(b.baseFieldID, f1.fieldID)
ORDER BY IFNULL(b.baseFieldID, f1.fieldID);

Properties on the container below are applied to the item itself if no container exists. Properties on the subcontainer below are applied to the container if no subcontainer exists, or the item itself if no subcontainer or container exists.

Creator Type Mappings

All creator types will be modeled as foaf:Person or foaf:Organization as appropriate, with these relations. We make extensive use of the ​MARC relator term ontology.
