Metadata standards: The single metadata schema used by the PDHC includes elements relevant to mutliple types of digital objects. Most fields are mapped to the Dublin Core which provides the possibility for records to be harvestable on a variety of platforms, including OCLC’s WorldCat.
Addition of new fields: The semantics include the common fields between institutions. Institutions may choose to include additional fields if needed for a particular collection. Any new common field must be established by consensus.
