  3. MetaMatrix Company OverviewUniform access to integrated information Vision – Universal bridge between information-consuming applications and enterprise information resources. Products– Lightweight design/deploy environment for project use. Enterprise-caliber information access system for enterprise deployments. Market–Global 5000 Organizations • Government Intelligence Agencies • Homeland Security • Financial Services • Pharmaceutical, Life Sciences • Manufacturing, Telecommunications • Independent Software Companies (ISVs)

  4. Data Interoperability Is At The Very Core of The Transformation Sought by the Federal Government One of the three enablers which drives domain-wide visibility: “… is a standard enterprise data architecture — the foundation for effective and rapid data transfer and the fundamental building block to enable a common logistical picture.” Army Lt. Gen. Claude Christianson “If you look at all the trends in the IT arena over the past 30 to 40 years, we’ve moved into an environment where we’ve got faster networks, more powerful processors, but it really comes down to the data” Michael Todd, DOD CIO office

  5. Dr. Linton Wells, as quoted in September’s NDIA Magazine, “…data compatibility may be an issue. Enabling digital interaction with nontraditional partners may require middleware or other programs that convert data from totally different formats …”

  6. NCES & Data Net-Centricity “To-be” = SOA Stack “As-is” = Application Silos Application Application Server Server … DBMS DBMS XML-centric Information Abstraction (= Data Services) How do you achieve? • Loose coupling • Map existing data to XML • Multi-source requests • Metadata visibility • Information security • Service access • Service discovery

  7. The Data Challenges Getting the right information to the right person at the right time requires: • Resolving data semantic and structural mismatches • Web service enabling legacy data systems (i.e., Net Centricity) • Mapping data sources to vocabularies like C2IEDM, NIEM, GJXDM, TWPDES, etc…. • Handling multi-source requests (data aggregation, mediation, fusion, federation) • Minimizing development and maintenance cost of custom code

  8. MetaMatrix – Quick Facts • Middle-ware, model-driven, data management • DoD proven (DISA, NSA, TRANSCOM, etc.) • Version 5 – Mature product which is still unique and ahead of the competition • NIAP certified and NSA-credentialed • Can handle the enterprise (or COI) perspective as well as the bottom-up perspective (data service enablement of legacy systems) • Can rapidly implement data integration strategies

  9. Some Key Value Propositions • Lower cost of new application development by 35 to 70% • Data interoperability is accomplished using COTS vs code • Reduce application maintenance costs • Enable detection of changes in data structures • No re-coding needed when data structures change • Fewer systems to maintain • Avoid the need for replication (OHIO) • Data owners keep control, managed access • Data abstractions are reusable components that generate tremendous value over time. • More adaptive computing

  10. Agenda • Company Overview & Value Proposition • Data Services Rationale & Best Practices • MetaMatrix Products & Capabilities • Achieving Information Sharing • Service Enabling Data Assets • Vocabularies & Semantic Interoperability • Bridging Structured/Unstructured Information • Customer Use Cases • Summary, Q & A

  11. Information Challenges Communities of Interest Agency Challenges • 100’s/1000’s of data sources • 100’s/1000’s of applications • Multiple access points/modes for apps • Understanding relationships/semantics • Data consistency • Data reuse – bridging data silos • Support for Web Services & SQL • Control & manageability, compliance • Security & auditing ? Information Resources Program Challenges • Multiple sources • Different interfaces/drivers • Different physical structures • Different semantics • Single interface to data desired • Real-time access to data • Performance • Maintainability as data changes • Maintainability as apps change Mission Challenges • Time-to-deploy • Agility - Responsiveness to change • Automation – Reduce cost of new development and operations • ROI of enterprise information

  41. Why Vocabulary Management? You can’t act on data alone! • Knowledge lies everywhere - you must involve data from disparate sources • The volume and disparately of data is too significant - you must enable machine involvement • Using semantics is not enough - you must be able to leverage domain concepts and terminologies • You must have the ability to infer relationships across the data

  42. Benefits of Vocabulary Management • Develop reusable information models and schemas • Implicitly improves data integrity • Capture business and technology requirements in a single vocabulary • Capture institutional knowledge • Enables semantic mining techniques for deeper data discovery and information sharing • Accelerate interoperability, web services and SOA development and deployment • Establish and maintain a common relationship across data sources • Establish and maintain compliance with industry exchange models • Reduce IT expenses by leveraging data in its native source • Reduce IT expenses associated with building and maintaining partner integration • Improved information sharing directly enhances decision making

  43. Knoodl.com - from Revelytix • A publicly-available collaborative wiki for collaborative vocabulary/ontology development • Extends the wiki metaphor with a formal model for semantic markup • Ideal for • Community of Interest (COI) based OWL development • Domain vocabulary creation and management • OWL registry/repository • Scheduled to go live 30 Oct 06

  47. Person Search - Conceptual Use Case Enterprise Information: Addresses Organizations Affiliations Accounts Transactions Call History Agreements Policies Relationships inherent in the search results link to enterprise apps, databases, and other repositories

  48. Incorporating Enterprise Data into Search • The usefulness of an organization's data is dependent upon understanding and applying context • In a typical text search application, context is supplied by document content, or metadata tags (filename, author, date, etc.) • An organization's structured data sources do not usually lend themselves to document-centric approaches • The context of structured data relies on: • metadata (typically implicit) for table names, column names, datatypes, and business descriptions for each • implied DB relationships such as foreign keys between tables • relationships (mappings) to a business data dictionary • The volume of structured data requires a combination of indexed and non-indexed approaches

  49. MetaMatrix and Google Google Search Appliance ContentRepository ContentRepository 2 Text Search w/ filtering criteria (optional) . . . ContentRepository Select & drill down to discover record details, related data links, & metadata Structured Data crawling & index build 3 1 RDBMS HTML I/F Field name look-up in Business Data Dictionary JDBC HTML I/F Connector Framework MetaMatrixServer ERP, CRM… Legacy Systems 4 Navigate to related data from Search UI Custom Application
