Health Level Seven,
The term “Level 7” refers to the highest level of the Open System Interconnection (OSI) model of the International Organization for Standardization (ISO). This is not to say that HL7 conforms to ISO defined elements of the OSI’s seventh level. Also, HL7 does not specify a set of ISO approved specifications to occupy layers 1 to 6 under HL7’s abstract message specifications. HL7 does, however, correspond to the conceptual definition of an application-toapplication interface placed in the seventh layer of the OSI model.
