Object Description Language (ODL) was the original interface definition language created by Microsoft for specifying interfaces to be used in OLE Automation. It was a superset of the OMG IDL.[1][2][3][4]

Microsoft provided a utility mktyplib to compile ODL files.[5]

The ODL was merged into the Microsoft Interface Definition Language.
