  2. OGMS integration approaches 1. OGMS - AM mappings (ambiguity, incompleteness) 2. Including OGMS terms as RM classes 3. Defining a new AM layer RM AM Pulse Medication order OGMS OpenEHR Disease core AM Particular archetypes Body Temperature Blood Pressure Pregnancy

  3. Translation from ADL to OWL archetypedefinition Observation data Event Series events Event_T data data Nortonscale data events Item List items Event Series events Element data Status transition data items List items Terminology General Physical Status

  4. Ontology bindings The term_binding section stores bindings between a particular term within the archetype and an equivalent concept in an ontology

  5. Equivalence relations Blood Pressure Arquetype Physiology ontology By linking the classes through a Necesary & Suficient condition we allow a reasoner to check data correctness and data coherence while preserves the ontology modularity during its exploitation.

  6. Enriched archetypes The Systolic pressure concept, defined in the archetype, is enriched with properties and attributes from the equivalent class within the Physiology ontology

  9. Conclusions • The Archetype Model should be improved in order to prevent concept overlapping. • Existing archetypes cover several concepts of the OGMS ontology, although some ambiguities have been revealed. • Three mapping approaches were presented for the integration of the OGMS ontology : • AM – OGMS, direct mapping. • Definition of the OGMS as a part of the Reference Model • Creation of a Disease layer between the RM and the AM • The translation from ADL to OWL offers several advantages for reusability, coherence checks and navigability between archetypes and clinical ontologies.
