2. Research
Goal
To
systema6cally
describe
methodological
knowledge
in
archaeology
so
that
it
can
be
easily
disseminated
and
reused
in
different
situa6ons.

3. Motivation
Prac%%oners
§ Difficult
to
communicate
ways
of
doing
§ Difficult
to
deal
with
con6ngencies
§ Wheel
is
being
reinvented
every
6me
§ One
size
does
not
fit
all
§ Poor
record
of
what
was
done
Researchers
§ No
base
for
the
study
of
cogni6ve
processes
in
archaeology

14. BeneCits
§ High-­‐quality
record
of
what
was
done
§ Checks
on
lifecycle
of
work
products
§ Facilitates
replanning
§ Reuse
of
knowledge
in
new
situa6ons
§ Base
for
research
on
cogni6ve
processes
in
archaeology

15. Open
Issues
§ Moving
from
descrip6on
to
prescrip6on
§ High
reliance
on
“previous
experience”;
lijle
coding
of
knowledge
§ Very
hard
to
reconstruct
methodology
employed

16. Conclusions
§ Descrip6on
is
not
easy
but
can
be
done
§ Dissemina6on
and
reuse
seem
possible
§ ISO/IEC
24744
extensions
necessary
and
in
progress
§ Open
issues
need
to
be
tackled
