Each DOF is capable of supporting one ormore subscriptions from a DOC.Actor: Device Observation ConsumerRole: Subscribes to PCD data.3.2.3 Referenced Standards• HL7 - Health Level 7 Version 2.5 Ch5 Query and CH7 Observation Reporting• ISO/IEEE 11073-10201 Domain Information Model• ISO/IEEE 11073-10101 Nomenclature3.2.4 Interaction Diagram20The PCD-02 is used by a Device Observation Consumer (DOC) to subscribe for PCDData from a Device Observation Filter (DOF). The transaction is based on the HL7Publish and Subscribe Query model where the Device Observation Filter (DOF) plays therole of Publisher and the Device Observation Consumer (DOC) plays the role ofSubscriber. The DOF defines a stream of data, but also agrees to selectively subset theRev. 1.1 TI: 2006-08-1519Copyright © 2005-2006: ACC, ACCE, HIMSS, and RSNA
