IRS Component Asset Registry(XML Registry/Repository) Prototype Senior leaders must champion reuse by expecting that assets be reused, recognizing projects and individuals that successfully reuse assets or publish them, and by making reuse a priority. - FEA Services and Components Based Architectures Version 3.5 Enterprise Data Management Office May 17, 2006 Sol Safran, PRIME Enterprise Data Management
IRS XML Framework • Objective: • Identify the target state of XML technology implementation for the IRS • Assess and adopt appropriate standards, practices, and tools for the IRS and its trading partners • Strategically transition current systems and legacy formats to modernized XML data exchange formats Adapted from a Department of Education, Federal Student Aid briefing. “XML: A Beginners Guide” Presented at the 2003 Electronic Access Conference in San Diego, CA.
Where We Are • MeF/CADE/E-Services • Common data requirements & all use XML • No common data components between them • Triples the size of the IRS vocabulary • Require custom interfaces • XML (XSD, XSL, etc.) managed within each project release • Vocabularies are project dependent • Cross project visibility does not exist • Difficult to discover and reuse external project components • Interfaces require significant transformation
Target Applications Each layer builds from shared components at the lower levels Interfaces (Services, API, GUI, batch, etc.) These are the interfaces where the messages are deployed. These are the exchange messages as deployed by projects Messages These are common message fragments, such as address. Components (aggregated terms) This is the controlled vocabulary. We aim to minimize, but not eliminate, terms outside of this universe. Terms
EDMO Goals • EDMO is tasked to build a common vocabulary for data exchange • Common data exchange components • XML service descriptions (WSDL) • ICD Process • So that we can: • Do a good job at managing data exchange • Identify reusable interfaces/minimize redundancy • Compose interfaces from messages/components • Enhance interoperability/minimize transformations • Provide enterprise exposure to available components • Assist projects using assets from previous projects • Reduce lifecycle costs for XML development/maintenance

ObjectType ClassificationScheme Defines type of information stored in the registry Allows registry customization for IRS-specific assets We defined IRS XML components
AssociationType ClassificationScheme Defines types of possible relationships between objects stored in the registry Allows registry customization for IRS-specific relationships We defined relationships between IRS XML components
SubjectRole ClassificationScheme Defines registry user roles Enables governance and fine-grained access control policy and authorization We defined IRS-specific roles
StatusType ClassificationScheme Defines the types of registry artifact status Allows registry to be customized for IRS specific status and enables governance, notification and workflow We defined IRS-specific status
Browse ComplexType Enables focused, encapsulated view of artifacts Enables exploration of relationships and dependencies between artifacts Reduces research and analysis time
Export ComplexType to ZIP File Where Stored Components Implemented as Message \Messages.xsd Assembly of Aggregate Component \AggregateComponents.xsd Assembly of Basic Component \BasicComponents.xsd Requires Specialized Datatype \SpecialzedDataTypes.xsd Organized within a folder structure by ‘namespace’
Next Steps • Prototype - 30 May Completion • Decision Point for Extended Prototype • Not acquisition • In IRS infrastructure; up to 1 Year • Add IRS requirements incrementally • Governance • Initiated contract support • Implement with extended prototype • Integrate QOD
