EAA2013 Presentation from Session B13 on New Digital Developments in Heritage Mangement and Research

1. How many archaeologists does it take to make a recording system?
What are the implications of using different recording methodologies and
terminologies for the data that we generate? What are the possible implications for
semantically linked and open data?

2. Overview of Presentation
Conceptual Frameworks
Examples of different
Methods
Similarities
Differences
Conclusions

3. The Archaeological Archipelagos

4. Data is derived at different stages in
archaeological project process
Archive data - may be
re-used as Start of
another Investigation
Investigation data -
recording on site
Analysis data -
studies, usually off-
site
Publication data - results
disseminated

5. Simplified Conceptual Reference Model for
Interoperability
Key Concepts for data
Interoperability
Contexts/SU, Finds, Groups,
Samples, Phases, Research
Objectives
Groups & Phases only come at
Analysis & Publication stages
May also depend upon recording
methodology

7. Examination of some examples of
Archaeological Recording Systems
UK - English Heritage
Germany - Bavaria
Italy - Rome
Catalhoyuk
Israeli - Tell es-Safi

8. Field record based data modelling
Model common ‘core’ of Archaeological
processes
Principle archaeological concepts modelled
as CRM entities & relationships
Limited degree of minute detail
Matrix holds stratigraphic relationships
N.B. Distinguishing positive Deposits
from negative Cuts

10. English Heritage
Recording Manual with CRM-EH

11. German - e.g. Gottingen & Bayer
Befunde - Stratigraphic Unit /
Context
1. Bayer -Befundbuch (positive
deposit?)
Bodenbefunde (soil SU)
Baubefunde (built SU e.g. Walls)
BefundeKomplex - Feature
(Group)
Planum = Multi-context plans by
level?

13. Italy
Rome - Lo Scavo Archeologico
manual
Unita startigraphica - Context
1.US muralia (walls)
2. US di rivestimento (painted
plaster)
3.Etc
Distinguish Stratigraphic Units and relationships
(matrix) & Positive & Negatives Units

14. Catalhoyuk
Units - Stratigraphic units,
similar to Contexts
Features - groupings of
units or more complex
structures, similar to
MoLA Groups

15. Israeli - Tell es-Safi
Stratum - distinct level of human activity
(horizon)
Locus - the basic features of excavation
(e.g. a floor, a pit, a dump). Recorded with
UID on a Locus card
Basket/Bucket - Unit of excavation with
all finds from the same Locus
Stratigraphic relations recorded between
Loci

16. Israeli – e.g.Tell es-Safi
Stratum - distinct level of human
activity (horizon)
Locus - the basic features of
excavation (e.g. a floor, a pit, a
Layer). Recorded with UID on a
Locus card
Basket/Bucket - Unit of
excavation with all finds from the
same Locus
Stratigraphic relations recorded
between Loci

17. With thanks to Gerald Hiebel
Example of Israeli
Recording Practice

18. Digging by fixed levels - Spits
Non-stratigraphic approaches
America - Texas (Coulson) system
Other examples in Europe?

19. Conceptual Models and Knowledge ResourcesConceptual Models and Knowledge Resources
 CIDOC CRM [ http://cidoc.ics.forth.gr/ ]
 CIDOC Conceptual Reference Model
 International standard ISO 21127:2006
 CRM-EH [ http://purl.org/crmeh ]
 English Heritage Ontological Model
 Extends CIDOC CRM for EH archaeological
domain
 SKOS [ http://www.w3.org/2004/02/skos/ ]
 Simple Knowledge Organization System
 RDF representation of thesauri, glossaries,
taxonomies, classification schemes etc.

20. Other important mechanisms for Semantic
interoperability include syntactic alignment
Shared Vocabularies
Using E55 Type and SKOS to relate
different terminologies together

CRM E55 types & SKOS work

26. Conclusions and Challenges
Different archaeological recording systems share
common conceptual frameworks and semantic
relationships
By conceptualising common relationships in our
different data sets at a broad level we can cross-
search data for patterns and broader answers to
related research questions
The technologies are being developed but is their
a common will for sharing archaeological data
openly in the interests of improving research
methods?
