HisArc-RDF project aims to share and reuse archaeological data, by articulating their description on semantic web repositories and standards. The project will test four data sets, samples of which will be determined to cover different archaeological themes, both in terms of vocabulary and data modelling: hydraulic structure, epigraphic data, ceramic and building structures. To achieve that, we want to reduce veracity concerns on descriptive vocabularies (from artefacts description to period names and limits) so that different datasets can be addressed and compared through concepts (instead of words) at a data level. For that purpose, we will create micro-thesauri (at sub-disciplinary level), then vocabulary and data model will be aligned in parallel with the semantic web repositories and CIDOC CRM to build a structured description of database fields as well as database variables. To address this, the project plans to interconnect Opentheso (thesaurus management tool), OntoME (ontology management environment) and IdRef (database for authority records). Finally, the project plans to bring together, through workshops, a large network of actors in order to disseminate good practices experienced by LOD implementation.
