OpenDocument.
(2) An early object-oriented compound document and component architecture governed by Component Integration Labs (CI Labs) in Sunnyvale, California. From 1992 to 1997, OpenDoc enabled the creation of custom documents that could contain data from different applications; for example, text, images and a spreadsheet.
OpenDoc was a superset of the OLE compound document technology, and OLE objects could be placed into OpenDoc documents and behave like regular OLE objects. OpenDoc components (Live Objects) were also CORBA compliant. See
OLE.
