• Op/onal

for

What
is
meant
by
reference
transforma/on?
• A
transforma/on
to
include
all
rules.
• A
transforma/on
not
part
of
the
collec/on
of
transforma/ons
of
the
produc/ve
environment.
• A
tool
for
quality
assurance:
• Explicit
for
the
output
metadata
• Implicit
for
the
input
metadata

How
to
build
a
reference
transforma/on?
• Single
output
module
for
all
input
formats
• Clearly
structured
• A
lot
of
documenta/on
/
comments
• Implemented
in
an
easily
accessible
form
as
an
XSL-­‐
transforma/on
• Possibility
to
be
used
not
only
by
experts
• Good
