1. 1 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

2. 2 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. IRS XML Framework

3. 3 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 Where We Are

4. 4 Applications Interfaces (Services, API, GUI, batch, etc.) Messages Components (aggregated terms) Terms This is the controlled vocabulary. We aim to minimize, but not eliminate, terms outside of this universe. These are the exchange messages as deployed by projects These are the interfaces where the messages are deployed. Each layer builds from shared components at the lower levels These are common message fragments, such as address. Target

5. 5 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 EDMO Goals
