  • 9. COI Knowledge Registry & Repository Needs
    • A Federated Knowledge Registry not only acts as an interface to a Repository of stored content, it formalises how information is to be registered and shared beyond a single enterprise or agency.
    • Specifically, a Federated Registry & Repository capability is required when there is a need for managing and accessing metadata across physical boundaries in a secure manner. Those physical boundaries might be the result of community-of-interest, line of business, system, department, or enterprise separation.
    • Irrespective of the boundary type, a Federated Registry & Repository must enable users to seamlessly access, share and perform analysis on information, including :
      • Maps of information dependencies across workflow
      • evidence of quality, statements of provenance and assurance
      • policies supporting security and privacy requirements e.g. HIPAA .
  • 10. COI Registry & Repository : Federated Content
    • Mappings for the critical path of information flowing across a business value chain e.g. ordering & payment of e-Prescription
    • Quality indicators such as statements of information integrity, authentication and certification e.g. electronic signature used for e-prescribing
    • e-Business Components (e.g. XSDs, Elements, Templates) and Universal Semantics Management
    Registry D Registry E Registry B Registry A Registry C
  • 11. COI Component Management Knowledge
    • Interacting entities need re-usable data (items) with known semantics
    • These items are required as (XML) Schema components
    • The Schema (document) and the Components must be shared within and often outside the organization
    • Components may use external components such as code lists
    • Domain Components must be managed cooperatively
    • Core components must be common
    • Data definition arbitration agreements are essential
    • Data types must be standardized
  • 12. ISO/TS 15000 OASIS ebXML Registry
    • One interface (HTTP, SwA, ebMS ) to classified knowledge content :
      • Electronic Forms
      • Web Services WSDL / WSRP
      • Collaboration Agreements
      • Business Process Requirements, Objects, Data
      • Domain specific Semantics and Relationships between Assets & Artifacts
      • SQL queries and APIs
  • 13. e-Business Knowledge : XML Registry Version 3
    • Registration and classification of any type of artifact
    • Namespaces defined for certain types of content
    • Messages defined as XML Schemas
    • Taxonomy hosting, browsing and validation
    • Links to external content
    • Built-in security (SAML)
    • Event notification, Event-archiving (audit trail)
    • Life cycle management of objects
    • Federation for inter-registry relocation, replication, references
      • metadata is stored in one registry; a registry may cooperate with multiple federations for the purpose of federated queries
  • 14. ebXML Registry Information Model (RIM) - COI Classification RegistryObject ClassificationNode Classification RegistryPackage ExtrinsicObject Service Association RegistryEntry ClassificationScheme The structure of the classification scheme may be defined internal or external to the registry A Classification instance identifies a ClassificationScheme instance and taxonomy value defined within the classification scheme Classification trees constructed with ClassificationNodes are used to define the structure of Classification schemes or ontologies Person
  • 15. NIST HL7 e-COI Registry of DMIMs, RMIMs, HMDs, and MessageTypes
    • HL7-specific classification schemes, especially the code hierarchies for the structural attributes in the RIM.
    • RMIM static models from technical domains, including finance, Patient Administration, Scheduling, Laboratory Orders, Research Trials, Pharmacy, Medical Records, Common Message Types, Message Control, Master File, and Clinical Documents
    • RMIM static models from the CMETs domain, each with a an association to the DMIM it is derived from (using external identifiers to the HL7 identification schemes) with external links to diagrams and descriptions, and a number of classifications by specific codes that are fixed by constraints on the RMIM.
    • RMIMs leads to one or more derived HMDs and MessageTypes.
    • Each registered artifact has ExternalLinks to its base UML diagrams, long html descriptions, and other visual display aids for presentation of base classes, attributes, relationships, and constraints.
    • OWL-related template artifacts submitted by HL7 participants active in the Templates technical committee
  • 16. IHE Integration XDS : Affinity Domain Sharing
    • The XDS Cross Enterprise Clinical Documents Sharing profile defines the (document) Registry as an actor that maintains metadata about each registered document in a document entry & enforces policies at the time of document registration
    • An XDS Document is a composition of clinical information that contains observations and services for the purpose of exchange with the following characteristics: Persistence, Stewardship, Potential for Authentication, and Wholeness (characteristics that are well defined in the HL7 CDA)
    • An XDS Folder provides a collaborative mechanism for several XDS Document Sources to group XDS Documents for a variety of reasons. XDS Documents may be placed into an existing Folder at any time, as long as they relate to the same patient.
    • A Document Source may only contribute documents with Document Codes and Health Facility Codes that draw from a Vocabulary Value Set that is approved by the Affinity Domain .
  • 17. XDS does not focus on Ontology .. however
    • BCM COI & XDS Affinity Domain defined by formal or informal organizational structures
    • Clinical information exchange exploits Controlled Vocabularies
    • Ontological Layers
      • Upper level ontology is focused on the non-volatile language and principles of a domain
      • Lower ontology is focused on the knowledge specific to particular community of practice (as formulated by the recognized experts)
  • 18. Ontology & other Semantic Content Considerations ….. artifacts that help agents communicate, coordinate, collaborate
    • XML provides syntax for structured documents, but imposes no semantic constraints on the meaning of these documents.
    • XML Schema is a language for restricting the structure of XML documents and also extends XML with datatypes.
    • RDF is a data model for resources and relations between them.
    • RDF Schema is a vocabulary for describing properties and classes of RDF resources, with a semantics for generalization-hierarchies of such properties and classes.
    • OWL adds more vocabulary for describing properties and classes e.g. relations between classes, cardinality, equality.
    • SKOS-Core is an [RDF & OWL] schema for representing controlled vocabularies and other types of Simple Knowledge Organization Systems .
  • 19. COI CHI (Consolidated Health Informatics) portfolio of Clinical Vocabularies
    • National Council on Prescription Drug Programs (NCDCP) standards for ordering drugs from retail pharmacies.
    • The Institute of Electrical and Electronics Engineers 1073 (IEEE1073) series of standards that allow for health care providers to plug medical devices into information and computer systems
    • Digital Imaging Communications in Medicine® (DICOM®) standards that enable images and associated diagnostic information to be retrieved and transferred from various manufacturers' devices
    • Laboratory Logical Observation Identifier name Codes® (LOINC®) to standardize the electronic exchange of clinical laboratory results.
  • 20. BCM Choice Points : Ontological Templates & Archetypes
    • Template & Archetype Choice Points significantly aids to comprehensibility, alignment, while promoting tracing and accountability when :
      • archetype is a computable expression of a domain level (clinical) concept in the form of structured constraint statements, based on some reference model (RMIM)
      • archetypes are aligned with Affinity Domain concepts
      • archetypes all have the same formalism i.e. may be part of a COP ontology but belong to only one or other ontological level
      • template is used to narrow the choices of archetypes for local or specific purposes (DMIM).
      • archetype defines constraints on reference model instances which express valid structure (i.e. composition, cardinality).
      • archetype defines constraints on instances of a reference model which express valid types and values.
  • 21. Challenge of Ontology Annotated e-Health Services
    • e-Health service information can be managed by two different e-Health service entities using different message structures.
    • ARTEMIS project providing a standard way of accessing the data by registering & storing
      • ontologies based on existing healthcare standards,
      • the semantic mapping between these ontologies,
      • invoke each others web services by semantic mediation.
    • Discovery of Services stored in a Registry need semantic service registry query mechanisms that leverage previous research linking OWL to the Registry Information Model
