2 Key Goals The CODIP program provides frameworks and components for intelligent processing of information based on its semantics.!application of an UML technology to leverage existing resources to provide knowledge engineering capability.!ontological processing components and services that can bring built-in knowledge processing capability to applications. 2

3 Applications and Products! Three primary product areas support of these goals: ODKD Kage Duet Duet to support visualization, application and management of ontologies using the UML/MOF engineering standards, Kage to support applications with analysis, translation, and repository functionality, and ODKD for semantics based publication of information to subscribers.!these products are built from library of reusable components that may be integrated into other applications. 3

4 Kage Knowledge Access Engine Ontologies Reference Domain Application AO DO RF UC CS Admin Lexical Processor NL Processors User Interface Document Processing Structure Processors Publish & Subscribe Manager File System Stores Knowledge Repository Text Stores Articulation Service Application Interface Rule Engine Non-Text Stores Review & Annotate Query Engine Matching Engine DBMS Stores! Framework for Intelligent Information Systems and implementation of ODM. Framework Integration of Open Source and third party NetBeans MDR, Kaon, Jess, Apache, and AT&T developed components 4

5 Driven Knowledge Dissemination! -based contentdefined publication channels! Topical Repository hierarchical archive of information! Publishers provide OWL Annotations linked to message content! Matching content blocks are published to subscribers of the matching channels 5

6 Duet Visualization and Engineering of OWL Ontologies!Current version Standalone file based Model Meta-data Source Descriptions Expert Knowledge» XMI V1.1» UML V1.4 Import and Export OWL!Future version Will migrate to OMG Definition Meta-model standard.» UML/MOF 2.0 Integration with Model Driven Architecture tools and IDEs Enhanced access to web services and ontology repositories. Managed Ontologies Services Services 6

7 ODM RFP Scope of Proposals Sought! A standard meta-model for ontology modeling Meta Object Facility! A UML2 Profile for depicting Ontologies! With at least mappings UML Profile Mapping Definition Metamodel Between ODM and the profile Between ODM and the W3C OWL/DL User Model Car public class Car {} Realizations <owl:class rdf :ID= Car /> Language Mapping 7

8 Why MOF Based Modeling is Important MOF XMI Of UML MOF MOF XMI Of ODM M3 UML XMI Of User Model UML ODM OWL XMI Of User Model M2 User UML Model User Instances User OWL M1 M0! ODM provides Broader interoperation within Model Driven Architecture process MDA tools access to to OWL and reasoning for MDA tools UML notation for OWL and OWL interpretation of UML 8

9 OMG Adoption Process Where is the ODM now? Board Approval Responses, Letters of Intent from Industry Request for Information TC Recommendation ADTF PTC Final Submission AB Initial Submission Evaluation and ODM Revision STILL in revision. Finalization and Revision Onto SIG Request for Proposal Subgroup Roadmap OMG Technical Plenaries meet at Technical Meetings which occur five times annually. With inputs from: Nicole Glazen - OMG Fred Waskiewicz - OMG 9
