• 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

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

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

• Specific mapping for the ArSol database

• Methodology can be shared

• Semantic homogeneization

- CIDOC-CRM to structure information

- PACTOLS to standardize vocabulary

• Web-semantic framework
