3. EDXL TC - January 2008 3 Domain Examples DOJ NIEM/LEX Fannie Mae EDI-esque XML PESC Dictionary and schema UBL schema and CCTS -Universal Business Language (UBL) -OASIS standard -Uses UML models and CCTS approach -Derived from xCBL and simplEDI approach -Supply chain schema with joint initiative EU / Asia / US -Developed by GTRI for DOJ community -Vocabulary based -LEXS schema built using NIEM vocabulary -Law enforcement and court applications -Developed for Education Department -form-style XML -Older XSD techniques for simple flat schema model -No re-use of common structures -Student loans and transcripts -Developed by BAH and NG for form-based application submissions -Translate previous paper form into multiple schema sections -Massive schema with extended namespaces -Set of functional transactions and configuration templates for managing and processing elections -Common set of components and vocabulary -Widely differing use patterns and items by country localization OASIS EML Grants.gov form based schema -Transactions replacing EDI -Overloaded reuse of structure components -Financial reporting data -Financial transaction data -Extended use of code sets to label transaction content / purpose

5. EDXL TC - January 2008 5 Exchange - Facilitation Needs For business communities: –Ability to create sharable templates for communities of practice that need consistent XML transaction handling definitions that are open and public. For business data analysts: –Printable rule documentation support and features. –Example domain templates within communities of practice –Supporting codelists implementation (Genericode). For programmers: –XML content manipulation support and rules ( xslt, XPath …) –Web services and SOA support

8. EDXL TC - January 2008 8 How does CAM work? CAM uses WYSIWYG approach to XML Starting with your XML sample – creates structure template from that + default data content model Next – add your structure use rules – optional / repeatable, date fields, allowed values, lookups Then make context business rules – cross field use rules, exclude, include, variables Save template – run against samples Eclipse editor tool makes this all easy to do! Deploy to production using jCAM processor

11. EDXL TC - January 2008 11 Illustrative EDXL requirements When Admissions Total > 50 –AND Deaths > 0 When AdultICU Bed type > 0 –AND Triage Quantity > 5 Require Facility State = CA, NV, NM

12. EDXL TC - January 2008 12 CAM rules syntax 50 and( // Activity24Hr /Deaths > 0)" action="restrictValues(// Activity24Hr /Admissions, ‘Alert – possible outbreak’) "/>

13. EDXL TC - January 2008 13 Value Proposition Making XML transaction handling simpler and predictable Extends and clarifies your existing XSD schema structures Quick and easy rule building from sample XML transaction Providing open sharable templates and documentation Re-use easier through support for includable components Ability to integrate to business processes and context Enabling more robust fault tolerant processing + versioning Open source, open public standard toolkit – editor + engine
