I added X-Filter parameter for detailing the user data:
http://localhost:8080/resources/HR/User.json?offset=1&limit=1&X-Filter=User.*

Here is the JSON response:
{"total":3,"limit":1,"offset":1,"UserList":[{"href":"http://localhost:8080/resources/HR/User/3.json","Id":3,"Active":true,"EMail":"joe.hammer@email.com","FirstName":"Joe","FullName":"Joe Hammer","LastName":"Hammer","Name":"joe","Type":{"href":"http://localhost:8080/resources/HR/UserType/standard/.json","Key":"standard"},"CreatedOn":"2014-02-18T14:43:27Z","UserIconPersonMetaData":{"href":"http://localhost:8080/resources/HR/IconPersonMetaData/3.json"}}]}
