Interoperable Object Reference

In distributed computing, an Interoperable Object Reference (IOR) is a reference to a CORBA object.

IORs may be “stringified,” or represented by a string of printable characters to facilitate sharing of object references by non-CORBA mechanisms such as HTTP, FTP, and e-mail. Stringified IORs consist of the prefix IOR:, typically followed by a sequence of hexadecimal digits.
