# Package: lra::technical::en13606::extract
The extract package defines the classes, relationships and constraints that comprise the Care Components reference model. The model is derived from and conforms to the EN 13606-1:2007 EHR extract model and specifies the record entry, organiser and supporting structures required communicate part or all of the EHR of an individual patient or service user. The derived reference model constrains many elements of the source model and adds a number of constrained specialisations of class ELEMENT. The constraints specified by these classes are concerned primarily with reducing variability of representation and ensuring that the structural components and bound terminological components act together to represent the computer-processable meaning of the data without unnecessary conflict or duplication. ## Classes: ### ACTIVITY_ELEMENT ### ATTESTATION_INFO ### AUDIT_INFO ### BOUND_DATA_ELEMENT ### CLUSTER ### COMPONENT_RELATIONSHIP_ELEMENT ### COMPOSITION ### CONTENT ### EHR_EXTRACT ### ENTRY ### ELEMENT ### EXTRACT_CRITERIA ### FINDING_OBSERVATION_ELEMENT ### FUNCTIONAL_ROLE ### GENERAL_ACTIVITY_ELEMENT ### INVESTIGATION_ACTIVITY_ELEMENT ### ITEM ### LINK ### MATERIAL_ACTIVITY_ELEMENT ### MATERIAL_ENTITY_ELEMENT ### OBSERVATION_ELEMENT ### PROPERTY_OBSERVATION_ELEMENT ### RECORD_ARTEFACT_ELEMENT ### RECORD_COMPONENT ### RELATED_PARTY ### SECTION ### UNBOUND_DATA_ELEMENT ## Class Diagrams ### extract package constrained classes ### extract package derived classes
