rdfs:label Exchange Rate Info
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.

URI http://purl.org/xro/ns#inverseRate
rdfs:label inverse rate
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.
