Metadata

•  The
term
metadata
refers
to
"data
about
data".
The

term
is
ambiguous,
as
it
is
used
for
two

fundamentally
diﬀerent
concepts
(types).

•  Structural
metadata
is
about
the
design
and

speciﬁca>on
of
data
structures
and
is
more
properly

called
"data
about
the
containers
of
data";

•  Descrip>ve
metadata,
on
the
other
hand,
is
about

individual
instances
of
applica>on
data,
the
data

content.
In
this
case,
a
useful
descrip>on
would
be

"data
about
data
content"
or
"content
about
content"

thus
metacontent.

•  Xpath
mapping
is
performed
simply
by

input

xpath
by
applying
a
string
manipula>on
func>on
to
it.

Condi>onal
Mapping

•  By
clicking
on
the

buVon
you
can
perform
a
condi>onal
mapping
i.e.
to

transform
the
value
from
an
input
xpath
by
using
condi>ons.
On
the
leh

the
drop
down
menu
with
the
type
of
condi>on
appears
that
can
be
AND

or
OR.
A
condi>on
is
set
using
one
of
the
following
func>ons.

–  Is
equal
to
–
sets
a
condi>on
that
is
sa>sfied
when
the
given
xpath
is
equal
to

the
given
value.

–  Is
not
equal
to
–
sets
a
condi>on
that
is
sa>sfied
when
the
given
xpath
is
not

equal
to
the
given
value.

–  Exists
–
sets
a
condi>on
that
is
sa>sfied
if
the
given
xpath
exists.
It
is

important
to
note
at
this
point
that
the
fact
the
xpath
of
an
element
exists
in

the
input
tree
does
not
mean
that
it
exists
for
all
the
data
in
the
imported

collec>on.
(In
other
words
the
input
tree
shown
on
the

aggregates
all
the

possible

found
in
the

Structural
Mapping

•  Structural
mappings
form
a
special
category
of
mapping.

As
you
may
have
no>ced
in
the
complex
types
of
the

target
schema
illustrated
in
the
mapping
area
text

“structural”
appears
instead
of
“unmapped”.
At
this
area

you
can
map
complex
elements
of
your
input
metadata.

•  Let’s
assume
you
have
a
complex
element
named
“B”
in

your
metadata
–
having
“C”
as
a
child
–
and
B
appears
3

>mes
in
only
one
record.
Also
assume
complex
element

“BTarget”
–
having
“CTarget”
as
a
child
–
in
the
target

schema.
If
you
make
a
structural
mapping
of
B
(by

dragging
it
and
dropping
it)
to
“BTarget”
and
then
you

map
“C”
to
“CTarget”
3
“BTarget”
complex
elements
will

appear
in
the
output
XML
having
“CTarget”
as
child
and

having
the
values
of
“C”.

•  By
clicking
on
the

icon
you
can
perform
a
value

mapping
i.e.
to
map
speciﬁc
values
of
your
input

metadata
to
speciﬁc
values
that
you
set.
