dati.culturaitalia is a pilot project realized in CulturaItalia dedicated to Open Data and Linked Open Data. Engine: Virtuoso Open-Source Edition Number of statements: 15.048.155 CulturaItalia Open data

The pilot project dati.culturaitalia.it contains open data sets of CulturaItalia released by the project partners with the Creative Commons Universal Public Domain Dedication (CCO). Currently dati.culturaitalia.it makes available metadata from: Italian Registry

• f Libraries, Accademia S. Cecilia, ArtPast, Digibess, ICCU, Internet

Culturale, Michael Italia, Polo Museale Fiorentino and Regione Marche, in addition to the Thesaurus PICO.

• Our SPARQL endpoint provides access to RDF metadata structured according

to the CIDOC - Conceptual Reference Model in the implementation of Erlangen CRM / OWL. Data can be searched over three querying interfaces, corresponding to three sections of dati.culturaitalia.it:

• Text search: here it is possible to perform free text searches over all

triples contained in dati.culturaitalia.it.

• SPARQL query: here you can try your hand at a SPARQL query. There

are also some examples of queries.

• iSPARQL query: here there is an even more complex querying interface

for advanced users.

CulturaItalia Next steps and perspectives

The main goal of the next activities is a strengthening of the actual LOD environment:

• to acquire and to integrate more data
• to obtain a better quality and uniformity of the published

data

• to extend the interoperability with LOD systems (linking data

with more LOD providers)

• to develop a more effective interaction for the users

24

Main tasks:

• Interoperability and integration with the MiBACT

SBN LOD project

• Integration of specialized thesauri and mapping

rules (internal and external) for a better uniformity

• f metadata contents
• Linking of the metadata contents to further

repositories published as LOD (e.g. the Getty Vocabularies)

• Enhancing of user interfaces for a better fruition of

the LOD repository contents and for a more effective interaction between the LOD platform and the traditional Cultura Italia environment CulturaItalia Next steps and perspectives
