  1. Roadmap to an IEPD What do developers need to do?

  2. Agenda • IEPD Deliverables • NIEM IEPD – Base Components Needed • Top Down or Bottom Up? • Tools and XML Technology • How do these tools all play together? • Dictionaries – NIEM / Domain • Reference Materials • Illustrative Examples • Resources and Contacts

  3. XML Schema IEPD Base Components 1  Exchange Schema XSD (aligns to information model, NIEM core plus domain dictionary and ICE NDR principles)  Documentation (Project business details (MS Word), NIEM cross-reference Spreadsheet) 2 Required items  XML artifacts (wantlist.xml, subset schema. Optional - extension, restriction and reference schemas ) 3  Examples & Test Cases (Realistic test XML instance(s) for exchange interoperability testing ) 4

  4. Technical Goals • Schemas for data exchange • To produce “exchange schemas” which offer a high degree of clarity, interoperability and reusability while being agnostic to the actual deployment software tools. • Documentation for understanding business context and usage • Supporting XML Artifacts • Examples and test cases for verification • Cross-reference to NIEM dictionary to ensure consistency, interoperability and reuse within and across domains • Alignment to domain data model components dictionary – interoperability across domain applications • Consistency: conforms to domain naming and design rules principles

  5. Top Down or Bottom Up? When requirements change – Regenerate Automatically!

  6. Status Today

  7. Tools and XML Technologies How do these tools all play together?

  8. XML Schema *Code list xsd Code list xsd NIEM domain schemas NIEM Exchange Schema 1 Exchange XSD 3 Exchange xml *Extension xsd 2 Wantlist xml *Constraint xsd xsd subset *Restriction xsd *Reference xsd LEGEND: * Optional Namespace

  9. XML Schema *Code list xsd Code list xsd NIEM domain schemas xsd subset Exchange xsd LEGEND: * Optional CAM Template *Extension xsd *Constraint xsd *Restriction xsd Namespace Approach in a Nutshell Structure XSD Collection XSLT tools process entire XSD collection Rules INGEST Re-factor to CAM abstraction format Documentation CAM = Content Assembly Mechanism

  10. Structure Rules CAM Template Documentation IEPD development Toolkit for IEPD base components generation • Run template evaluation report • Compare to NIEM dictionary - create wantlist.xml - create spreadsheet • Generate business rules report • Generate XML instance(s) 1 2 PROCESS Suite of menu options and tools in CAM toolkit editor (run custom xslt scripts on CAM template xml) 3 4

  11. Leveraging SSGT • Generating IEPD base components • Exchange schema ingesting • Principles and Rules check evaluation report • Cross-reference to NIEM dictionary • Wantlist.xml generation • NIEM online SSGT uploading + subset schema generation • Excel spreadsheet of cross-reference • Business Rules documentation • Example XML instance 1 2 3 4

  12. Reference Materials Illustrative Examples References and Contacts

  14. NIEM cross-reference spreadsheet Formatted view in Microsoft Excel of import of cross-reference report details (from generated XML file)

  15. NIEM online SSGT and wantlist.xml Options menu and Load Wantlist option with resulting load of subset details
