• Designing how to move from requirements to code• Handling complexity– Platforms, libraries, technology evolution, languages,

testing, methodologies, requirements, organization, work, people, …

• Using tools– Abstraction & Views– Visualization– Verification– Generation– Communication

The Application Architect’s Job

The Modelling Dilemma: Two Masters

• The “Model Centric” Master– Sometimes referred to as “Top Down”

• The “Code Centric” Master– Sometimes referred to as “Code Up”

• The value is in the integration between the two approaches…

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

“Future of UML” Request for Information

• Issued December 12, 2008 (chaired by S Cook)• Response deadline August 17, 2009• Responses:

– 01Communications– ARTISAN Software Tools– SOFTEAM– Microsoft– SAP AG– Oose Innovative Informatik Gmbh– Systems Engineering DSIG– No Magic Inc– IBM– Model Driven Solutions– HL7/OMG Working Group– Oracle– BAE Systems, CSC, Mega International, NIST, oose– 88Solutions– AdaCore, CoFluent, EADS, INRIA, THALES– Sparx Systems Pty Ltd

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
