Yes... thanks to our data model we can express currencies as 3-letter
ISO codes /or/ IRIs. Basically, any currency that has an ISO-4217 code
should use it, otherwise - use a dereference-able IRI. See the
"currency" vocabulary term for more info:

Looks very close to the concept of a Transfer (and how it is expressed)
in PaySwarm:

http://purl.org/commerce#Transfer

You may also want to look at the Transaction concept:

http://purl.org/commerce#Transaction

The vocabulary mapping from LETs to PaySwarm is:

payer       -> com:source
payee       -> com:destination
currency    -> com:currency
quantity    -> com:amount
createdtime -> com:date (we may end up using dc:created)
description -> rdfs:comment
state       -> NO MAPPING
