20 Conclusion I: There is no single access point specialised on the written heritage from the Medieval and Renaissance Europe

21 Conclusion II: earch possibilities regarding the history of collections and texts are limited

22 Vision Biblissima How to answer complex questions using interoperability?

23 Federate databases... by establishing a common RDF framework: ntology Data in RDF Enable (complex) queries Thesaurus

24 ntology Definition I : A conceptual map of the terms and relationships that constitute a domain. For example, a library ontology would likely include "books," and would note that books often have "authors," that authors have "birth_years," and that books also often have "titles," "subtitles," and "subjects." The terms and relationships in an ontology can then be used to determine the metadata to be recorded, as well as the ways in which data can be retrieved from a dataset. Although ontologies pre-date the emantic Web, they have been brought to prominence by it. ource : Getting tarted Guide (Harvard University)

25 ntology Definition II : A formal model that allows knowledge to be represented for a specific domain. An ontology describes the types of things that exist (classes), the relationships between them (properties) and the logical ways those classes and properties can be used together (axioms). ource : Linked Data Glossary (w3c)
