04. Get a single entity from an entity set

GET http://services.odata.org/V4/TripPinService/People('russellwhyte')

To get a particular entity from a collection, append a key segment. By default, key segments in OData services are bounded by parens because they may be composite keys, e.g., OrderLine(OrderId=1,LineNumber=1) or alternate keys, e.g., Person(SSN='000-00-0000') and Person(2115) both address the same resource. Some OData services use normal URL segments for key segments, e.g., Orders/1. This is not recommended because of the scenarios mentioned above.
