dim xschema status
DIM XSchema Status
  • XSchema modifications:
    • Added capability to associate values with data types
    • Created DIM_Values.xsd library containing textual object information such as reference, object id, object name, etc.
      • Reason:
        • Facilitates access and manipulation of this type of information.
        • Reduces size of DIM.xsd.
        • Facilitates upgrades to DIM.xsd.
    • Created separate schema library for DIM data types
      • Reason:
        • Facilitates access and manipulation of data types.
        • Makes data types reusable by other application.
        • Facilitates upgrades to DIM.xsd
        • Reduces size of DIM.xsd
    • Optimized XSchematron rules in DIM.xsd.
    • Applied XML Schema best practices for optimization purposes in different areas of the DIM.xsd.
  • Developing draft IEEE 11073 DIM XML Schema document
    • Used IEEE 11073.1.1.2 aECG Nomenclature template as example.
conformance test tools based on 11073 dim schema
Conformance Test Tools(based on 11073 DIM Schema)
  • ICSGenerator
    • Facilitates creation of vendor conformance statements.
    • Provides Medical device data such as parameters or attributes with value ranges and restrictions. [This data can be used as needed by Message Maker (in addition to testing options, data source(s) and HL7 V2.x profile file) to build the test messages.]
  • http://www.nist.gov/medicaldevices
icsgenerator capabilities
ICSGenerator Capabilities
  • Generates ICS’s as required in DIM document.
  • Ensures common format for ICS generation.
  • Generates an electronic (XML) version of device data model based strictly on the IEEE 11073 DIM.
    • Includes private or manufacturer-specific extensions.
  • Provides validation against DIM Schema.
    • A device data model generated using this tool can be validated against an updated version of the DIM XSchema.
  • Provides high level semantic interoperability
    • Ensuring correct containment relationship and terminology at the object class and related attribute, notification and behavior level.
    • Device ICS’s comparison capability aids in identifying potential interoperability issues.
icsgenerator capabilities cont
ICSGenerator Capabilities (cont.)
  • Dynamic tree generation
  • Ability to generate UML diagrams
  • Device data model comparison reports.
    • Exported to HTML or PDF document format.
  • General and Service Support ICS captured in XML
  • Transport ICS for IRDA Cable Connected profile.
  • Ability to handle private or manufacturer-specific extensions.
  • DIM MOC, Attribute, Notification and Behavior ICS tables generated into HTML.
icsgenerator capabilities cont1
ICSGenerator Capabilities(cont.)
  • Ability to add an Application Guidance Statement for the MOC
  • CREATE/DELETE Service Support for MOC's
  • Ability to Add Attribute Access for an attribute. (e.g., GET, SET, SCAN...)
  • Enhanced ability to Add/Remove Attributes, Behaviors and Notifications.
  • Code added to ICSGenerator that enables users to add/delete Composite MDS to the containment tree
icsgenerator enhancements since last wg meetings boca raton sept 06
ICSGenerator Enhancements(since last WG meetings [Boca Raton, Sept 06])
  • Interface upgrades
    • Added menu bar to re-start application
    • Added PDF report generation for ICS Tables.
    • Added pop-up menu to MOC in JTree to manipulate the objects.
    • Improved JTree collapsing behavior when manipulating the objects.
  • Created an installer to automatically install ICSGenerator.
icsgenerator work in progress
ICSGenerator Work-in-Progress
  • Value/Data type association
    • Creating a DIM data type library
  • Adding value input dialog
  • Mapping observation values to HL7 OBX segments
    • OBX-2, OBX-3, OBX-4, OBX-5, OBX-6 and OBX-7
  • Updating ICSGenerator code to compile and run under Java 1.5
  • Updating Users Guide to include latest ICSGenerator changes
conformance test tools continued based on 11073 dim schema
Conformance Test Tools (continued)(based on 11073 DIM Schema)
  • ValidatePDU
    • Provides a basic syntax and structure check for a set of captured messages.
  • Future Enhancements
    • Translating BER/MDER XML
      • Needed for 11073 syntax/structure/semantic testing
  • http://www.nist.gov/medicaldevices
next steps
Next Steps
  • NIST 11073 DIM XSchema
    • Document IEEE 11073 Normative Standard
      • PAR approved 9/15/06?
      • Project Plan under development
      • Maintenance issue of electronic file (versus paper documentation) in Standard
  • ICSGenerator
    • Add Remaining Transport Profiles
    • Continue Enhancing Interface and Usability; Documentation
    • Work w/ IHE PCD Team and Medical Device Vendors
    • Unit of Measurement (e.g., convert IEEE units of measurement to UCUM, if adopted)
    • Mapping IEEE x73-10101 (Nomenclature) ‘Unit Codes’ to Reference Identifiers
  • Look into issue of Unit Attribution Semantics (long range)
next steps continued
Next Steps (continued…)
  • IHE PCD Test Case Development (Year 2)
    • Support HL7 Profile Development (using MWB and Message Maker)
      • Output test messages
    • Obtain data values
      • To be used w/ Message Maker test generation
    • Research potential link of IEEE X73-basedICS files (XML) into MWB and Message Maker
call for help
Call for Help…
  • IEEE X73/IHE WGs, Vendors/Clinical Engineers
    • Validate NIST XSchema
    • Install and evaluate ICSGenerator
      • Provide feedback on utility and functionality
    • Recommendations for enhancements
