A First Attempt at Describing, Disseminating and Reusing Methodological Knowledge in Archaeology
Cesar Gonzalez-‐Perez Patricia Mar2n-‐Rodilla Ins6tute of Heritage Sciences (Incipit) Spanish Na6onal Research Council (CSIC)
Research Goal
To systema6cally describe methodological knowledge in archaeology so that it can be easily disseminated and reused in different situa6ons.

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

Tests
Let’s put together a paperless Data Acquisi3on process.
New Modified Unnecessary
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
Copyright © 2013 Cesar Gonzalez-‐Perez 14
Open Issues
§ Moving from descrip6on to prescrip6on § High reliance on “previous experience”; lijle coding of knowledge
§ Very hard to reconstruct methodology employed
Copyright © 2013 Cesar Gonzalez-‐Perez 15
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
