1 Rules and Policy based handling of XML in Government Contexts including NIEM David Webber, James Cabral and Dana Florescu Seattle, Washington, July 2013.

2 Background Managing information privacy and access policies is a critical need and technical challenge for government Desired solutions should be both ubiquitous and syntax neutral, yet at the same time incorporate a simple and lightweight approach that meets legal policy requirements through the application of clear, consistent, and obvious assertions Support use with National Information Exchange Model (NIEM) approach Slide 2Copyright RuleML © 2013

3 DoD NIEM Adoption NIEM military domain “will support development of information exchange specifications across the full range of military operations.” NIEM will be used unless component can show compelling reasons DoD Chief Information Officer Teri Takai : Lt. Gen. Mark Bowman, Joint Chiefs of Staff CIO/J6 3

5 The NIEM Framework NIEM connects communities of people who share a common need to exchange information in order to advance their missions, and provides a foundation for seamless information exchange between federal, state, local, and tribal agencies. Much more than a data model, NIEM offers an active user community as well as a technical and support framework. Formal Governance Processes Online Repositories Mission-Oriented Domains Self-Managing Domain Stewards Data Model XML Design Rules Development Methodology Predefined Deliverables (IEPD) Tools for Development and Discovery Established Training Program Implementation Support Help Desk & Knowledge Center

6 Agenda Approach Overview Use Case Example XML and NIEM* Grappling with Complexity Simple Solution Option - Semantic Data Querying Summary Q & A Slide 6Copyright RuleML © 2013 * National Information Exchange Model –

7 Approach Overview Enable business information analysts to apply and manage policy profiles; Provide a clear separation between content and policy artifacts; Allow reuse of policies across content instances; Provide a clear declarative-assertions-based method, founded on policy approaches developed by the business rules technologies community; Leverage open software standards and tools.

8 Use Case Example California Child Welfare Services – Case Management and Case Court Submission Levels of information – HIPAA – Case Workers – Judge – Doctors – Parents / Guardians Slide 8Copyright RuleML © 2013

9 Current Business Process Flow

10 “To Be” Business Process Architecture

11 XML and NIEM Court Report NIEM IEPD Existing XML Schema (XSD) of court report exchange structure Handles general court case reporting Need to tailor structure to California needs and medical child welfare case handling Map from existing California and physicians case management databases to NIEM XML Slide 11Copyright RuleML © 2013

12 INGEST Load Schema into Template. XSLT tools process entire XSD collection XSLT tools process entire XSD collection XSD Collection Structure Rules Documentation *Code list xsd Namespace * Optional XML Schema xsd subset *Constraint xsd *Extension xsd *Restriction xsd Industry Domain schemas Code list xsd LEGEND: Exchange xsd NIEM Exchange Schema CAM Template *CAM – Content Assembly Mechanism –

13 CAM Template Capabilities Fine grained dynamic rule –based control of XML structure components and validation Template has separate sections for structure, rules and annotations allowing easy programmatic handling Mature full featured visual editor tool Supports rendering to models and visual maps Ability to generate XML instances and map to/from SQL data stores

14 CAM Runtime Tools Validation Services Mapping Services / XML / JSON CAMV Engine XML instance CAM template rules XML validation results Open-XDX Engine CAM template rules XML instance generated SQL JDBC connection XML to JSON service JSON instance generated Optional CAMV = CAM Validation services Open-XDX = Open XML Data eXchange services (‘open data’)

15 CAM Editor Tools Editing / Dictionary / Mapping Target Renderings (via XSLT transforms) Structure Rules Documentation CAM Template SQL CAM EDITOR XML Dictionary XSD schema MindMap Model UML Model XML instance Documentation HTML, XML, Excel XML Dictionary

16 Data Mapping Editor NIEM XML Structure Case Management Database Drag and Drop

17 Example Data Mapping

18 Example NIEM XML Inserted text values

19 Grappling with Complexity. Court Report Data Model – XSD structure is generalized “catch all” open content structure Issues and Resolutions – Every element is repeatable, optional, nillable ! – Replace with actual real content usage rules: Required, excluded, optional Remove ALL nillable clauses Use Repeatable only when applicable multiple data – Map to actual SQL database sources – Ensure consistent and simple information exchange Slide 19Copyright RuleML © 2013

20 Simple Solution Uses OASIS CAM Template Template Rules expressed using XPath assertions – Layer 1 – actual content control rules – Layer 2 – access policy rules Template policy role based XML filtering – HIPAA only content – Parent / Guardian content – Physician content Slide 20Copyright RuleML © 2013

21 Layer 1 - Content Control Rules Exclude item Rules Content Rules Make Optional Rules By default every item in template is Required

22 Layer 2 - Policy / Role Rules Policy Rules Excluded for HIPAA access

23 Open-XDX Runtime Layer 1 content rules Layer 2 policy rules Open-XDX Engine CAM template rules Filtered XML instance generated SQL JDBC connection Role + Query Parameter(s)

24 Payload XML/JSON Data Exchange Open XDX - Conceptual Architecture Existing Information Databases SQL Open Data XML Open-XDX SQL Rapid Deploy JDBC connection Control template contains information of the exchange structure design and DB mapping rules of data tables and columns Template Structure Rules DB Mappings Parameters Configuration Packaging Delivery Service API Send RESTful Webservice (WADL) or SOAP (WSDL)

26 Option – Semantic Querying Need to know what precisely a medication does that is referenced in patient records Obtain classification codes from NIH Master Drug database of generic and named SNOMED semantic clinical terms repository (RDF) Instantiate RDF/OWL store in Oracle database with SPARQL lookup of drug classification details Lookup drug name, obtain master code, then reference SNOMED, return set of medical details; notice many drugs have multiple purposes. Slide 26Copyright RuleML © 2013

27 Implementation Strategy Step 1 - Load SNOMED ontology into Oracle Semantic RDF Graph Step 2 - Perform OWL logical inference in Oracle database Step 3 – Semantically Analyze the XML input (Java) – Take the input XML, parse the XML and locate the PatientDrugInfo content in the XML – Perform Text search to find matching URIs for the given patient drug information (NIH master drug catalogue) – Perform Semantic search using SPARQL queries to find relevant concepts (following class hierarchy) in the SNOMED ontology (asserted + inferred) – Enrich the PatientDrugInfo text field with all the additional information found Step 4 - Return the XML back Slide 27Copyright RuleML © 2013
