This
page
provides
mappings
for
Element
Definition
(see
Mappings
to
Other
Standards
for
further
information
&
status).
Many
other
standard
frameworks
define
frameworks
for
defining
"data
elements".
These
overlap
to
some
degree
with
the
ElementDefinition
type.
This
page
provides
general
mappings
between
ElementDefinition
and
the
other
frameworks.
One
important
consideration
with
regard
to
other
Element
definition
frameworks
is
the
scope
of
the
definition.
Many
of
these
definition
frameworks
use
the
term
"Data
Element"
to
refer
to
a
data
item
that
is
collected
and
stored
with
provenance,
such
as
when
it
was
collected,
who
recorded
it,
etc.
In
this
specification,
that's
an
Observation
,
and
the
definition
of
this
kind
of
data
element
is
an
ObservationDefinition
,
or
a
StructureDefinition
that
contains
several
different
atomic
data
items.
An
ElementDefinition
in
this
specification
is
a
narrower
notion,
solely
around
the
characteristics
of
a
single
element,
its
definition,
and
its
value
domain
.
Other
frameworks
-
especially
ISO
11179
-
are
used
in
both
ways,
sometimes
with
no
formal
differentiation
between
them.
For
this
reason,
the
mappings
on
this
page
are
very
provisional,
and
are
provided
with
the
intent
of
helping
implementers
understand
the
possible
relationships.
Mappings
to
the
LOINC
master
table
which
defines
observations
-
this
may
be
relevant
when
the
element
describes
an
observable
piece
of
data.
This
is
particularly
relevant
in
profiles
of
observation,
and
also
related
to
ObservationDefinition
Mappings
to
ISO
11179
which
details
how
the
ElementDefinition
class
relates
to
the
ISO
11179
framework.
Note
that
the
principle
differences
are
that
FHIR
does
not
differentiate
between
a
Data
Element
and
a
Data
Element
Value,
and
the
FHIR
specification
is
heavily
type
dependent.
Also,
the
FHIR
specification
includes
constraints
and
other
concerns
that
are
outside
the
scope

11179
