Knowledge Mediation Goals : Re-Use, Re-Usable, Re. Useful • Support Communities of Practice & Communities of Interest – Locally, regionally, nationally, internationally • Use Natural Knowledge models suitable for wide audience not just IT support specialists e. g. the Patient – Ability to mitigate business vocabularies and multi-lingual challenges • Automate sharing Semantically rich Meta. Data e. g. e-Health – provide discovery, understanding, and exchange of Electronic Health Record (EHR) information – Enable Providers, Pharmacy, Health Plans / PBM’s (pharmacy benefit management), and other Agencies to create service processes that support internationally agreed business process definitions, trust mechanisms and process control methods NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e.

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. NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e. Business Registry : Repository
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 eprescribing Registry B Registry A e-Business Components (e. g. XSDs, Elements, Templates) and Universal Semantics Management NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e. Business Registry : Repository Registry C Registry E Registry D
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 • • • NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e.

NIST HL 7 e-COI Registry of DMIMs, RMIMs, HMDs, and Message. Types • • • HL 7 -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 HL 7 identification schemes) with external links to diagrams and descriptions, and a number of classifications by specific codes that are fixed by constraints on the RMIMs leads to one or more derived HMDs and Message. Types. Each registered artifact has External. Links to its base UML diagrams, long html descriptions, and other visual display aids for presentation of base classes, attributes, relationships, and constraints.

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 HL 7 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.

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) NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e. Business Registry : Repository
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.

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.

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 NSF Collaboration Expedition 12/2004 Ontology Pragmatics ; BCM & e.
