    • Outline
      Information Cycle
      Linked Dataand Museum Data
      LODAC Museum
    • Information Cycle
      Information can be created only based on existing information
      No information can be created out of nothing
      Collect – Use & Create
      Value of information is how much it is used
      No value for information without use
      Use & Create – Publish
      Accumulation of information is the wealth of society
      Distribution of information is the health of society
      Publish – Share -- Collect
      Create
      &
    • Information Cycle
      Before Gutenberg
      Media
      Hand-writing books
      Oral communication
      Information Cycle is
      Slow
      Small amount
      Few People
      After Gutenberg, the age of Mass media arrived …

    • LOD Cloud(Linking Open Data)
    • Linked Data – Four Rules
      Linked Data is “Web of Data”
      (Traditional) Web is “Web of Documents”
      What is Linked Data?
      RDF triples
      Can refer others
      Can be referred by others,
      Four Rules for Linked Data
      Use URIs as names for things
      Use HTTP URIs so that people can look up those names.
      When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL)
      Include links to other URIs. so that they can discover more things
      Linked Data, TBL, http://www.w3.org/DesignIssues/LinkedData.html
    • Importance of data in public sector as Linked Data
      In principle, it should be shared
      It is the basic knowledge of our society
      Data in public sector
      Library
      Museum
      Archive
      Government
    • Challenges for Linked Data in Japan
      Lack of culture of sharing
      Immature community for linked data
      Lack of central data Set
      Difficulty of multi-lingual data
      Anyway let’s start!
    • LODAC Project
      Open Social Semantic Web Platform for Academic Resources
      Providing platforms for Linked Data
      Practicing data accumulation and publishing
      Interested Areas
      Museum information
      Geographical information, especially geographical names
      Local information

    • Museum data as LOD
      The state-of-the-art of museum information in Japan
      Distributed
      Self maintained
      Isolated
      Opaque
      Self designed
      Messy
      Aggregating and associating museum information
      LODAC-Museum (tentative)
    • Over 1.4 billion collections
      Over 1,000 organizations
    • http://lod.ac/ (open on December 11)
    • LODAC Museum – Main work
      Gathering of data
      Thesaurus, museum collections, etc
      Standardization of data
      Representing data from different sources in a unique form
      Integration of data
      Identifying data
      Associating the same data
      Publishing and share of data
    • Data sources
      Thesaurus and authority sources
      日本美術シソーラスDB絵画編(Thesaurus of Japanese Art)
      国指定文化財データベース(DB for National Designated Cultural Property)
      文化遺産オンライン(Cultural Heritage Online)
      Museum Collection (14 museums)
      国立美術館所蔵作品総合目録検索システム(国立国際美術館,京都国立近代美術館,東京国立近代美術館) (4 Nat’l Museums)
      国立西洋美術館 (Nat’l M. Western Art)
      京都国立博物館 (Kyoto Nat’l Museum)

      香川県立東山魁夷せとうち美術館
    • Metadata design
      Basic Structure
      Work – Creator – Museum
      Interoperability is more considered than correctness in the domain
      DC> DCTerm> FOAF> iCal >SKOS>NDLSH> RDA> CIDOC CRM
      Keep it flat as long as possible
      Metadata elements
      Work: 46
      Person: 23
      Org. 13
      Bib. 12
    • Integration Policy
      How to integrate data from different sources
      sharing of responsibility
      Each source is responsible for its data
      Identifying IDs for data and managing data with the IDs
      LODAC is only responsible for integration
      Assigning original IDs and associating other IDs to them
      Data from Source B
      Integrated data
      Data from Source A

    • Integration of Person Data
      Matching of Creators
      Base: List of Artists from Thesaurus of Japanese Art
      Target: Creators of collection in museums + Dbpedia
      Method: String match of names
      Results: Links from artist nodes to work nodes are added
      Links
      LODAC data
      Link to Work
      DBpedia
      Basic Informationfor Creators
    • 徳島県立美術館 Tokushima Pref. Museum
    • 東京近代美術館 National Museum of Modern Art, Tokyo
    • 国指定文化財データベース DB for National Designated Cultural Property
    • Tokushima Pref. Museum
      Thesaurus for Japanese Art
      DB for National Designated Cultural Property
      National Museum of Modern Art, Tokyo
      Fukui Pref. Museum
    • Data size and Integration Results
      Museum collections
    • What can LOD give Museum Data?
      Connectivity!!
      Open Connectivity makes new values for museum data
      Connect to data in other areas
      Connect to UGC (User Generated Contents)
    • Local Information with Museum data
      Museum LOD + Local LOD / Sightseeing LOD / Geo LOD
      e.g.,
      Tour visiting museums with a focus
      Joint event with local festivals
      Tour for food related historical events

      37
    • User Generated Contents for Museum Information
      1. Statue of Sarasvati
      2. Ryohoji Temple
      弁財天像
      3. Theme Song for Ryohoji
      4. Event
      Contributions by non-experts
      e.g.,
      Personal comments for Buddha statues
      Records of visiting museums
      Media-mix events
    • Publish museum data as LOD
      Let’s make museum data open and shareable
      Change “cultural heritage” to “cultural resources”
      (art/culture) * information = Promotion of the Nation
      Beyond collaboration of Museum Library Archives(MLA)
      MLA3(Museum Library Archives, Arts and Academia)
      More users, more various types of usage
    • Make arts and culture more dynamic and more energetic
      Pop Culture
