An important element of NanoHistory is the ability to collate and disambiguate existing open data resources. This means point to data outside of NanoHistory. The objective is not to have a complete listing of all identifiers for an entity, but to provide enough key types to link to larger more extensive catalogues and resources which do. In the case of archival research or datasets that aren't yet part of the Linked Open Data world, or do not have clear identifier systems, we allow the creation of ad hoc identifier types as needed. Below is the current list of identifiers used in Nanohistory.
