SDO is a specification developed by an industry consortium (OSOA). The current version of the specification is 2.1 and can be found at http://osoa.org.
Several companies have implementations of SDO in their products including: BEA, IBM, Oracle, SAP, RogueWave, XCalia. IBM's implementation of SDO version 1 was done at Eclipse, but that project has since been deprecated and moved to Apache (Tuscany). Tuscany is currently implementing SDO 2.1. There is also an Oracle implementation of SDO that was recently proposed for Eclipse (the EclipseLink project). It will also be SDO 2.1, but with different features and performance characteristics than Tuscany. In terms of standardization, SDO for Java is going to be standardized via the JCP (JSR 235). Other languages are moving to OASIS. Frank.
