data model

Some preliminary notes on a data model.

The model is based on Nomisma ontology which is based on CIDOC-CRM. The following overview is incomplete!

Entity types

• nmo:Denomination
• mno:Mint
• dcmitype:Collection, nmo:Collection
• crmdig:D1_Digital_Object
• nmo:Monogram
• foaf:Person
• org:Membership
• dcterms:PeriodOfTime
• nmo:Hoard
• crm:E28_Conceptual_Object, skos:Concept
• prov:ProvenanceStatement
• prov:Create, prov:Activity, prov:Replace, prov:Modify
• nmo:Find
• nmo:TypeSeriesItem

Coin

An individual physical coin. See http://nomisma.org/documentation/contribute/#physical-coins. In Nomisma more general nmo:NumismaticObject (coins, tokens, banknotes...) with

Findspot

An event that took place at a Location See http://nomisma.org/documentation/contribute/#findspot

Place

A location, preferably from a gazetteer such as GeoNames or Wikidata. Nomisma and CRM differentiate E53 Place (the abstract place) and E94 Space Primitive = geo:SpatialThing (the specific location) because places may have unknown or relative location. We may combine both into one for simplicity.

Example: Trier as a Mint: http://nomisma.org/id/treveri

{
  "uri": "http://nomisma.org/id/treveri",
  "prefLabel": { "en": "Trier", "de": "Trier" },
  "location": {
    "type": "Point",
    "coordinates": ["6.641389","49.756667"]
  }
}

Hoard (nmo:Hoard)

Collection of coins found together. Has a findspot.

Example: http://nomisma.org/id/olivers_orchard_hoards
