Slide 3: Enterprise Data Management Office – Mission & Vision
Partnered Organization IRS / PRIME / MITRE
• Establish and implement an Enterprise-wide data management program. • Define long term objectives and identify projects and activities that help attain those objectives. • Recruit and maintain project staff and integrate services and deliverables into the overall environment. • Develop a strategic plan, management reports, schedules, finance and budget • Coordinate the support, planning prioritization and monitoring of activities that manage IRS data at the enterprise level to meet the business needs of the agency
Enterprise Data Manager
Data Engineering Working Group (DEWG)
Data Management Issues Resolution Team (DMIRT)
Data Policy & Strategic Planning Data Administration
• Provide the necessary infrastructure, policies, standards and tools which provide for common integrated, consistent and effective data management practices • Develop, promote and oversee compliance with policies • Develop and maintain the Enterprise Conceptual and Logical data models
Data Architecture Database Administration
• Coordinate and ensure the optimal use of IRS agency resources and assets in the physical manipulation of data and data artifacts • Develop and implement plans for data transition, data migration, data conversion, COTS data stores, and custom data stores • Facilitate the creation, storage, manipulation, integration, distribution, use and management of enterprise level shared metadata and XML Registry • Support application and engineering projects in developing enterprise compliant data solutions.

Slide 4: IRS Enterprise Data Management Office – Background
• Data management work and XML standards being performed by PRIME Enterprise Data Management (EDM)
– EDM is EDMO support contractor – CSC is PRIME integration contractor for IRS Systems Modernization – Coalition of CSC, IBM, Northrop Grumann, and others

Slide 5: IRS Enterprise Data Management Office – Background
• XML plays large role in Systems Modernization – Tax returns and forms from external providers – Storage of tax returns as received, plus modifications – Inter-system messaging IRS had many independent XML initiatives – Inter-operability was jeopardized – Wheels were being re-invented – Each project learned as it went
•

Slide 6: IRS Enterprise Data Management Office – Background
• Tax data in XML
– Also increasingly: tax returns are converted to XML and processed/stored – All tax forms must be retained as originally submitted … increasingly in XML from 3rd party providers and large corporations – Eventually most tax forms and returns will be in XML format in IRS – Tax Year 2004 return projections: • 1120 (Corp): 6M • 94x (Employment): 30M • 1040: 134M
•
Impact of XML
– 2004 projections • 1120 returns (Corp): 100k • 94x returns (Employment): 29M – XML schemas can amplify data • Some 1120 schema instances up to 350 MB
6
Slide 7: Managing IRS XML Standards - Benefits – Improved Systems Interoperability
• • • • Common business vocabulary Common XML message content Reduce interface development costs Facilitate re-use and interoperability
– Improved Data Quality
• Known sources and locations of data • Contradiction between databases removed • Typing to ensure values
– Improved Taxpayer Interaction
• More accurate, timely information
– IRS commitment to states/external developers
7
Slide 8: Managing IRS XML Standards - Goals
• Organize stakeholders • Pull together internal and external knowledge and best practices
– Identify existing industry best practices – Liaison with external organizations – TIGERS, OASIS, FED XML Working Groups, etc. – Leverage IRS project knowledge and lessons learned across the IRS
• Provide direction, standards and guidelines
– Define XML specific standards and guidelines – Define appropriate uses of XML
• Plan for XML architecture/infrastructure support (e.g. XML Registry, XML tools, etc.)
8
Slide 9: Managing IRS XML Standards - Process • Fact finding • Develop initial standards to assist team • Conduct workshops • Important considerations
– Maintain enterprise perspective – Try to minimize impact to projects
• Communicate process and findings to stakeholders • Formalize • On-going
9
Slide 10: Managing IRS XML Standards – Results & Where Next
• Formalized XML standards & guidelines - ongoing
– – Enterprise Data Standards & Guidelines Stakeholder Working groups
•
Architectural Issues
– – – – – What and how to XMLize, and what not to • E.g., messaging, OLTP vs. reporting/analytics, etc. Structural commonalities and differences • XML for messaging vs. processing vs. data storage Structural variations for different kinds of processing (SAX vs DOM, vs Custom) Architecting for data sharing, re-use, and interoperability Architecting for performance and scalability • Technology/performance implications of data volume amplification
• • • • •
Standard XML schema based on Enterprise Logical Data Model XML Registry Organization outreach (TIGERS, OASIS, XML Working Group, etc.) Taxonomy SCORM

Slide 11: Managing IRS XML Users - Stakeholders
• XML Stakeholders:
– Large, diverse group (100+) – Major IRS organizations, all levels of projects, external organizations – Members participate in XML working groups – Recently expanded scope to include stakeholder presentations
