This paper describes the creation of linked data for cultural heritage domain, using semantic technologies. The Gothenburg city museum data are described according to an ontological model combining a series of upper-level and domain specific ontologies, such as PROTON and CIDOC-CRM, triplified and interlinked with data from LOD, e.g. DBpedia. The implementation is done as a reason-able view of the web of data and the data are loaded in OWLIM semantic repositoyr.

    • A Reason-able View of Linked Data for Cultural Heritage Mariana Damova, PhD, Dana Dannélls
    • IntroductionLinked Open Data combining facts and knowledge from different datasets is the ultimate goal of the Semantic WebNeed for convincing real life use cases demanstrating the benefits of these technologiesMacManus, the Founder and Editor-in-Chief of ReadWriteWeb defined an exemplary test for the Semantic Web cities around the world which have Modigliani art works Museum Reason-able View September 2011 #2
    • FactForge of Ontotext solves the Modigliani queryThe cultural heritage domain can become a useful usecase for the applicationof semantic technologies. http://factforge.net Museum Reason-able View September 2011 #3

    • Linked Open Data – the Vision Tim Berners-Lee graphs published on the web and explorable across servers in a manner similar to the way the HTML web is navigated Design principles of Linked Open Data – Use URIs to identify things. – Use HTTP URIs so that these things can be referred to and looked up ("dereferenced") by people and user agents. – Provide useful information about the thing when its URI is dereferenced, using standard formats such as RDF/XML. – Include links to other, related URIs in the exposed data to improve discovery of other related information on the Web.

    • Reason-able View – Linked Open Data ManagementUsing linked data for data management is considered to have great potential forthe transformation of the web of data into a giant global graph (Heath, & Bizer,2011). Still, there are several challenges that have to be overcome to make thispossible, namely: • LOD are hard to comprehend; • Diversity comes at a price; • LOD is unreliable; • Dealing with data distributed on the web is slow; • No consistency is guaranteed.Using reason-able views (Kiryakov et al., 2009a) – a solution to LOD management. Museum Reason-able View September 2011 #8
    • Reason-able View – Linked Open Data Management• An approach for reasoning with and managing linked data - an assembly of independent datasets, which can be used as a single body of knowledge with respect to reasoning and query evaluation - lowering the cost and the risks of using specific linked datasets for specific purposes• The linkage between the data - at the schema level - at the instance level• Accessible via - SPARQL endpoint - keywords• Queries with predicates from different datasets• “Federated” results from different datasets Museum Reason-able View September 2011 #9

    • Museum Reason-able View – Data• Requirements: - the ability to handle generic knowledge, such as people, institutions, and locations - the ability to handle specific subject domains, such as the cultural heritage andmuseums• Datasets covering the Generic Knowledge of the Museum Reason-able View. - DBpedia - the RDF-ized version of Wikipedia, describing more than 3.5 million thingsand covers 97 languages. - Geonames - a geographic database that covers 6 million of the most significantgeographical features on Earth. - PROTON - an upper-level ontology, 542 entity classes and 183 properties. Museum Reason-able View September 2011 #11
    • Museum Reason-able View – Museum Data Models• CIDOC – CRM developed by the International Council of Museum’s Committee for Documentation(ICOM-CIDOC) an upper-level ontology for cultural and natural history for museum professionals to perform their work well 90 classes and 148 properties - Entity, Temporal Entity, Time Span, Place, Dimension, - Production, Creation, Dissolution, Acquisition, Curation Museum Reason-able View September 2011 #12
    • Museum Reason-able View – Museum Data ModelsK-samsök, the Swedish Open Cultural Heritage (SOCH)• a Web service for applications to retrieve data from cultural heritage institutionsor associations with Cultural Heritage information.• includes features which are divided in the following categories: - Identification of the item in the collection - Internet address, and thumbnail address - Description of the item - Description of the presentation of the item, including a thumbnail - Geographic location coordinates - Museum information about the item - Context, when was it created, to which style it belongs, etc. - Item specification, e.g. size, and type of the item – painting, sculpture and the like Museum Reason-able View September 2011 #13

    • Museum Reason-able View – Gothenburg City Museum Data 8900 museum objects in two museum collections – GSM and GIM 39 properties describe each museum object The Gothenburg city mueum data is integrated by using predicates from CIDOC-CRM, PROTON, MAO, and linkages to DBpedia Museum Reason-able View September 2011 #15
