Classes

Exchange Rate Infoc back to ToC or Class ToC

IRI: http://purl.org/xro/ns#ExchangeRateInfo

is defined by
http://purl.org/xro/ns
Describes the currency exchange rates between a currency pair, consisting of a base currency (e.g. USD) and a counter currency (e.g. EUR). The class further specifies attributes for the time of conversion, the currency rate, the inverse of the currency rate, and human-readable meta descriptions encoded in rdfs:label and rdfs:comment. If applicable, it is recommended to use dcterms:source to link from the xro:ExchangeRateInfo object to the URI of the currency conversion API that was responsible for the generation of the respective exchange rate.

Object Properties

baseop back to ToC or Object Property ToC

IRI: http://purl.org/xro/ns#base

is defined by
http://purl.org/xro/ns
This property adds a base currency to the xro:ExchangeRateInfo class. The expected range value for this property is a DBPedia currency class. You can obtain a list of all currency instances in the DBPedia dataset by clicking on the following link: <a href="http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=select+distinct+%3Fs%2C+%3Fcode%0D%0Awhere+%7B%0D%0A++%3Fs+a+dbpedia-owl%3ACurrency+.%0D%0A++%3Fs+dbpprop%3AisoCode+%3Fcode+.%0D%0A%7D&format=text%2Fhtml&timeout=0&debug=on">click me</a>.

counterop back to ToC or Object Property ToC

IRI: http://purl.org/xro/ns#counter

is defined by
http://purl.org/xro/ns
This property adds a counter currency to the xro:ExchangeRateInfo class. The expected range value for this property is a DBPedia currency class. You can obtain a list of all currency instances in the DBPedia dataset by clicking on the following link: <a href="http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=select+distinct+%3Fs%2C+%3Fcode%0D%0Awhere+%7B%0D%0A++%3Fs+a+dbpedia-owl%3ACurrency+.%0D%0A++%3Fs+dbpprop%3AisoCode+%3Fcode+.%0D%0A%7D&format=text%2Fhtml&timeout=0&debug=on">click me</a>.

Data Properties

inverse ratedp back to ToC or Data Property ToC

IRI: http://purl.org/xro/ns#inverseRate

is defined by
http://purl.org/xro/ns
The xro:inverseRate property describes the exchange rate of a given currency pair, meaning that 1 unit of the counter currency is exchanged for X units of the base currency. The xro:inverseRate property denotes the inverse of the xro:rate property.

ratedp back to ToC or Data Property ToC

IRI: http://purl.org/xro/ns#rate

is defined by
http://purl.org/xro/ns
The xro:rate property describes the exchange rate of a given currency pair, meaning that 1 unit of the base currency is exchanged for X units of the counter currency.

time of conversiondp back to ToC or Data Property ToC

IRI: http://purl.org/xro/ns#timeOfConversion

is defined by
http://purl.org/xro/ns
The xro:timeOfConversion attribute of an xro:ExchangeRateInfo class is determined by a timestamp of the last currency conversion.
