What are they?
The HL7 EHR System Functional Model provides a reference list of over
160 functions that may be present in an Electronic Health Record
System (EHR-S). The function list is described from a user perspective
with the intent to enable consistent expression of system
functionality. This EHR-S Functional Model, through the creation of
Functional Profiles, enables a standardized description and common
understanding of functions sought or available in a given setting
(e.g. intensive care, cardiology, office practice in one country or
primary care in another country).

The HL7 EHR Interoperability Model establishes an industry consensus
view of "What is EHR Interoperability?" It provides a reference list
of characteristics of (and requirements for) interoperable EHR
records. EHR/IM conformance criteria permit EHR records to be
validated (vis-à-vis the interoperability characteristics) at points
of EHR record origination, transmission and receipt. The EHR/IM may be
profiled to meet the specific needs of care settings, regions,
implementations and uses.

As part of the work in preparing the HL7 EHR Interoperability Model,
extensive research was conducted around the topic of
"interoperability" - how is the term currently defined and used in
actual practice. This research is reported in the Coming to Term:
Scoping Interoperability for Healthcare whitepaper and supporting
documents. While these materials are incorporated in the download file
for the HL7 EHR Interoperability Model, they are also available in a
separate download "package".
