Agenda: 

Agenda Market-Driven Data Strategy Electronic Marketplace For XML DII-COE XML Registry XML Coordination & Guidance

Data Management Challenges: 

Data Management Challenges No Single Standard can be imposed! Various DoD communities will adopt multiple “standards:” Government (message, database, symbology), Commercial, International, de facto/legacy etc. Expect Heterogeneity!

XML Management Challenges One Language, Many Vocabularies: 

XML Management Challenges One Language, Many Vocabularies <lat_deg>30N</lat_deg> <latitude units=“degrees” hemisphere=“north”>30</latitude> <latitude> <hemisphere>N</hemisphere> <degrees>30</degrees> </latitude> These 3 XML fragments are: Equally valid ways to express the same data in XML Well-formed per W3C Specification Different terms and XML structures NOT INTEROPERABLE!

Management OptionsContrasting Styles: 

Management Options Contrasting Styles Top-down, “Command” versus Market LOOSE TIGHT SPECTRUM OF CONTROL What will work for Defense? Recommended Approach: Market with Some Controls

Principles from President Bush: 

Principles from President Bush Citizen-centered Results-oriented Market-based Mar-15-01

Key Management Mechanism : 

Key Management Mechanism Market Visibility Developers and Warriors Asking for Help!! What data is available? Who has it? How do I get it? Which data is better?

Market Players: 

Market Players Developers Re-use available data components and/or Register new ones they have created Community Data Managers Use Market visibility services for configuration control (e.g., current version distro, version change notification etc.) Defense Acquisition Policy Makers Use Market metrics for acquisition oversight (e.g., reflecting Program participation, specific data component re-use etc.)

Market Features: 

Market Features Low barriers to entering the process Electronic Marketplace as Visibility mechanism Components as unit of exchange (commodities) Communities of Interest (COIs) as arenas for trade Program Engineers as primary “traders” Must engage “hands on” Developers who build important Data Resources!

Electronic Market DISA’s Data Emporium : 

Electronic Market DISA’s Data Emporium “One Stop” Publish & Subscribe for Defense Metadata Data Component Registration COI Creation & Management New Version Jan 01 Public Access via WWW plus Password protected and classified instances http://diides.ncr.disa.mil/shade Purpose: visibility and re-use, not standardization through mandate!

Marketplace Rules: 

Marketplace Rules Data Component Registration Consult Emporium before creating new components and reuse existing data where practical Indicate planned use of components by formally subscribing to them Register additional components or recommended mods Communities of Interest (COIs) Formation Created “as required” when someone will agree to manage Requirements for new COIs staffed with: Existing COI Managers Senior Service/Agency engineers Flag Level Review Board

Market Organization: 

Market Organization Configuration Control features: Distributed across DISA Engineering Staff and “Hands On” Managers from multiple COIs Capitalizes on existing configuration control bodies COI “Managers” govern data in multiple physical forms Coordination Venues: Individual COI “boards” COI Managers’ Forum Data Technical Working Group (Any voice heard) Ad hoc contacts with other Government, Allied, and Commercial activities } Configuration Control Organizations

Electronic Market Place XML Registry : 

Electronic Market Place XML Registry IOC May 99 Public Access via WWW (FOUO) Password protected Improved Version Jan 01 10K elements and schema SIPRNET version early CY01 Handles XML Registration Namespace Creation & Mgt CIO EB Expanding Scope XML Registration Policy and Plan http://diides.ncr.disa.mil/xmlreg Purpose is management visibility and re-use, not standardization through mandate!

XML Market Place Rules: 

XML Market Place Rules XML Registration Requirement Developers using XML for public interfaces should: Consult XML Registry before creating new XML components and reuse existing XML where practical Indicate planned use of Registered XML by formally subscribing to it Submit (where required) additional XML components (with amplifying information) or recommended modifications to existing components Creation of XML Namespaces Formed “as required” when someone will agree to manage Requirements for new Namespaces staffed with: Existing Namespace Managers Senior Service/Agency engineers Flag Level Review Board CIO EB kept apprised

XML Convergence Process: 

XML Convergence Process Namespaces & managers chartered “as required” Overlap among Namespaces is inevitable Namespaces act as “Buckets” for in-use XML Managers run Working Groups (collaborative venues) Entry points for XML Registry submissions & Developer requirements Status mechanism (developmental, operational, deprecated) provides ability to express COI preference Enterprise Namespace holds DoD “common” XML Identifies and Registers “Common” XML from COI Namespaces Governed by Namespace Managers’ Forum Registry provides XML “Market” visibility Includes system and developer usage information

Registration is Easy!: 

Registration is Easy! Developer identifies or creates XML not currently registered. Developer creates Registry package for new XML and proposed mods. Developer submits Registry package via on-line capability, specifying an existing namespace. http://diides.ncr.disa.mil/xmlreg/XMLUserSubmitForm.cfm Registry Ops reviews submittal for propriety and registers package as “Developmental.” Receiving Namespace Mgr reviews submittal and accepts or rejects as properly belonging to another namespace. If rejected, Namespace Mgrs Forum determines whether another namespace will accept it. Upon developers' request, entries rejected by all namespaces are retained in TBD namespace. Namespace Mgrs may review accepted XML to change status from “Developmental” to “Operational.”
