2. • Objectives of ArSol: data management, processing and analysis
▪ ArSol = Archives du Sol (DBMS : 4e
Dimension)
▪ data management and research
• Background to the interoperability of digitized resources
▪ context of the MASA Consortium
(MASA = Mémoire des Archéologues et des Sites Archéologiques)
▪ funded by the TGIR HumaNum (Humanités Numériques)
▪ international standard CIDOC-CRM (ISO 21127:2006)
• Implications for ArSol and committed procedures
▪ bringing ArSol on line
▪ mapping: matches between CIDOC-CRM classes and properties,
and database fields in ArSol

INTRODUCTION
3. CIDOC-CRM ontology: between abstraction and reality
▪ Spatio-temporal definition of archaeological entities
- archaeological entities → recording → research archive
- interpretation with features and artefacts
▪ The need to appropriate the CIDOC Conceptual Reference Model

4. Mapping the FAIT and MOBILIER tables
in the ArSol database
▪ Selection of basic archaeological information
- information common to all excavations:
features and artefacts
- retain only the data characterizing the
feature or object

- archive vs resources:
divergent concepts
- the semantics specific
to archaeology
- how control the
conformity of the
mapping?

III.INTEROPERABILITY
15. • Specific mapping for the ArSol database
• Methodology can be shared
• Semantic homogeneization
- CIDOC-CRM to structure information
- PACTOLS to standardize vocabulary
• Web-semantic framework
→ Toward a RDF version with the SKOS format
