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

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

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

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.)

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

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
