Project VBI ERAT LVPA The Internet Tracks of the Roman She-Wolf
Traditional corpora: • very high quality, difficult to maintain, difficult to search, uncorrelated to
uncorrelated between each other.Altogether: • A conglomerate of highly interrelated archaeological sources
• of overwhelming detail and volume
Ubi-erat-lupa: A European “Culture 2000” Project• An aggregation of complementary scientific databases and corpora
describing finds with inscriptions and iconography of the Roman era
• to create a body of unique archaeological knowledge in digital form.

VBI ERAT LVPA Objective
• creation of a global index about a set of semi-autonomous sources for global access to the unified knowledge
• integration of complementary information under a common ontology/schema and identification of common elements in different sources
• development of an integration algorithm that converges to the best state of knowledge und continuous update
• creation of a research tool for formulating queries of archaeological content to detect contextual relationships that cannot be derived from interpreting the sources in isolation
5CAA2004, April 13-17, 2004 Doerr, Schaller, Theodoridou
Approach
• Develop a semantic network based on the CIDOC CRM model to integrate the complementary archaeological sources
• Data, relevant to global querying over all contents, are extracted, transformed and stored in an RDF repository, that is incrementally updated over time.
Integration in two phases:• source schema is intellectually interpreted in terms of the CIDOC model
• “non canonical” data reported to respective source
• mistakes in sources removed, quality of source improved
• actual data automatically transformed and stored into an RDF repository
• an a posteriori data cleaning process removes as many duplicates as can be (semi-) automatically detected
