Closing Date

Get the closing date of a hoard based on coin type URIs provided in the request parameter.
Webservice Type : REST
Url : nomisma.org/closingDate?
Parameters : identifiers (coin type URIs divided by a pipe '|'), format ('json' or 'xml', default 'xml')
Result : returns an integer which represents the year. Negative numbers refer to B.C. dates.

Get Findspots

Get all individual find spots for a given skos:Concept defined by the id parameter or for a given coin type (nmo:TypeSeriesItem) defined by the coinType parameter
Webservice Type : REST
Url : nomisma.org/getFindspots?
Parameters : id (of Nomisma ID) OR coinType (full URI for a coin type) OR symbol (full URI for a symbol [monogram, mint mark, etc.])
Result : returns geoJSON for features (points or polygons)
Examples: apis/getFindspots?id=denarius, apis/getFindspots?coinType=http://numismatics.org/crro/id/rrc-408.1a, apis/getFindspots?symbol=http://numismatics.org/ocre/symbol/monogram.ric.10.marcian.1

Get Hoards

Get all hoards associated with a given skos:Concept defined by the id parameter or for a given coin type (nmo:TypeSeriesItem) defined by the coinType parameter. If the skos:Concept is a hoard, then only one point is returned.

Webservice Type : REST
Url : nomisma.org/getLabel?
Parameters : uri (of Nomisma ID), lang (two-letter ISO language code), format ('json' or 'xml', default 'xml')
Result : returns the label in given language, or English as default.

Webservice Type : REST
Url : nomisma.org/getRdf?
Parameters : identifiers (Nomisma ids divided by a pipe '|'), format ('xml', 'ttl', 'json'; default 'xml')
