Introduction to Object Identifier and Uniform Resource Identifier

This presentation provides an overview of two types of identifiers commonly used in health care data exchange – object identifier (OID) and uniform resource identifier (URI).

Pan-Canadian Standards use OIDs to distinguish between objects by assigning a numeric string that enables other systems to understand the unique information that is being shared between various systems. A URI is used to identify things on the semantic web. It is easier to read and can be a name and/or locator.
