So can I use the following JSON to represent the data structure?

{
   "a": "com:Transfer",
   "com:forTransaction":
"<http://redbankexample.com/transactions/20110104#7827982>";
   "com:source": "<http://redbankexample.com/accounts/12345#account>",
   "com:destination": "<http://greencardexample.com/accounts/54321#account>",
   "com:amount": "8.00",
   "com:currency": "USD",
   "rdfs:comment": "Transfer of $8.00 on 2010-10-16 at 12:34pm -
Paying Jane back for pizza last Monday"
}
