Diagram Definition Currently there is no standard for interchanging UML diagrams effectively, or for defining precisely what legal UML diagrams are The Diagram Definition RFP is developing a new “meta-standard” for defining and interchanging diagrams, led by IBM There will (eventually) be a standard for UML diagrams, based on DD

14. Plan for future Step 1: UML 2.4 - a short-term revision doing metamodel/XMI cleanups on formal issues that inhibit implementation generation and interchange – Completed July 2010 Step 2: UML Specification Simplification RFP. Keep the UML definition the same, but reorganize the specification so that it is consumable and manageable – Completed December 2010 Step 3: UML cleanup RFPs – Refactor and simplify – “Unbundle” and reduce dependencies – Eliminate unintended inheritance – Correct conceptual errors – Reorganize OMG modeling architecture – Eventually leading to UML 3.0
