  2. 2. Outline<br />Information Cycle <br />Linked Dataand Museum Data<br />LODAC Museum <br />
  3. 3. Information Cycle<br />Information can be created only based on existing information<br />No information can be created out of nothing<br />Collect – Use & Create<br />Value of information is how much it is used<br />No value for information without use<br />Use & Create – Publish<br />Accumulation of information is the wealth of society<br />Distribution of information is the health of society<br />Publish – Share -- Collect<br />Create<br />&<br />
  4. 4. Information Cycle<br />Before Gutenberg<br />Media<br />Hand-writing books <br />Oral communication<br />Information Cycle is<br />Slow<br />Small amount<br />Few People<br />After Gutenberg, the age of Mass media arrived …<br />Create<br />&<br />
  5. 5. Two social layers on information cycle with Mass Media<br />Writer, Artist, Scholar<br />Mass media<br />Government<br />Create<br />&<br />
  6. 6. Two social layers on information cycle with Mass media<br />Writer, Artist, Scholar<br />Mass media<br />Government<br />Collect<br />Create<br />Use<br />Create<br />OrdinaryPeople<br />&<br />&<br />
  7. 7. Two social layers on information cycle with Mass Media<br />Writer, Artist, Scholar<br />Mass media<br />Government<br />Create<br />OrdinaryPeople<br />&<br />
  8. 8. Web<br />Internet<br />Open Door to Information Cycle for Ordinary People<br />Create<br />Search Engine<br />Web Server<br />&<br />Web Browser<br />HTMLEditor<br />Information Cycle with Web <br />
  9. 9. Web<br />Information Cycle<br />Web accelerate Information Cycle in<br />Speed<br />Quantity<br />People<br />Create<br />&<br />
  10. 10. Web<br />Internet<br />Create<br />Search Engine<br />Web Server<br />&<br />Web Browser<br />HTMLEditor<br />Information Cycle with Web <br />
  11. 11. Metadata is the platform of Information Cycle<br />Metadata<br />&<br />Create<br />&<br />
  12. 12. Linked Data will be the platform of Information Cycle on the content layer<br />Metadata<br />Linked Data<br />&<br />Create<br />&<br />
  13. 13. LOD Cloud(Linking Open Data)<br />
  14. 14. Linked Data – Four Rules<br />Linked Data is “Web of Data”<br />(Traditional) Web is “Web of Documents”<br />What is Linked Data?<br />RDF triples<br />Can refer others<br />Can be referred by others,<br />Four Rules for Linked Data<br />Use URIs as names for things <br />Use HTTP URIs so that people can look up those names. <br />When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL) <br />Include links to other URIs. so that they can discover more things<br />Linked Data, TBL,<br />
  15. 15. Importance of data in public sector as Linked Data<br />In principle, it should be shared <br />It is the basic knowledge of our society<br />Data in public sector<br />Library <br />Museum<br />Archive<br />Government<br />
  16. 16. Challenges for Linked Data in Japan<br />Lack of culture of sharing<br />Immature community for linked data<br />Lack of central data Set<br />Difficulty of multi-lingual data<br />Anyway let’s start!<br />
  17. 17. LODAC Project<br />Open Social Semantic Web Platform for Academic Resources<br />Providing platforms for Linked Data<br />Practicing data accumulation and publishing<br />Interested Areas<br />Museum information<br />Geographical information, especially geographical names<br />Local information<br />…<br />
  18. 18. Museum data as LOD<br />The state-of-the-art of museum information in Japan<br />Distributed<br />Self maintained<br />Isolated<br />Opaque<br />Self designed<br />Messy<br />Aggregating and associating museum information<br />LODAC-Museum (tentative)<br />
  19. 19. Over 1.4 billion collections<br />Over 1,000 organizations<br />
  20. 20. (open on December 11)<br />
  21. 21. LODAC Museum – Main work<br />Gathering of data<br />Thesaurus, museum collections, etc<br />Standardization of data<br />Representing data from different sources in a unique form<br />Integration of data<br />Identifying data<br />Associating the same data<br />Publishing and share of data<br />
  22. 22. Data sources<br />Thesaurus and authority sources<br />日本美術シソーラスDB絵画編(Thesaurus of Japanese Art)<br />国指定文化財データベース(DB for National Designated Cultural Property)<br />文化遺産オンライン(Cultural Heritage Online)<br />Museum Collection (14 museums)<br />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)<br />国立西洋美術館 (Nat’l M. Western Art)<br />京都国立博物館 (Kyoto Nat’l Museum)<br />奈良国立博物館 (Nara Nat’l Museum)<br />福島県立美術館 (Fukushima Pref.

  23. 23. Metadata design<br />Basic Structure<br />Work – Creator – Museum<br />Interoperability is more considered than correctness in the domain<br />DC> DCTerm> FOAF> iCal >SKOS>NDLSH> RDA> CIDOC CRM<br />Keep it flat as long as possible<br />Metadata elements<br />Work: 46<br />Person: 23<br />Org. 13<br />Bib. 12<br />
  24. 24. Integration Policy<br />How to integrate data from different sources <br />sharing of responsibility<br />Each source is responsible for its data <br />Identifying IDs for data and managing data with the IDs <br />LODAC is only responsible for integration<br />Assigning original IDs and associating other IDs to them<br />Data from Source B<br />Integrated data<br />Data from Source A<br />crm:P55_has_current_location<br />dc:creator<br />Work<br />dc:references<br />dc:references<br />crm:P55_has_current_location<br />crm:P55_has_current_location<br />Museum<br />dc:creator<br />dc:references<br />dc:references<br />dc:creator<br />Creator<br />dc:references<br />dc:references<br />24<br />
  25. 25. Integration of Person Data<br />Matching of Creators<br />Base: List of Artists from Thesaurus of Japanese Art<br />Target: Creators of collection in museums + Dbpedia<br />Method: String match of names<br />Results: Links from artist nodes to work nodes are added <br />Links<br />LODAC data<br />Link to Work<br />DBpedia<br />Basic Informationfor Creators<br />

  35. 35. Data size and Integration Results<br />Museum collections<br />
  36. 36. What can LOD give Museum Data?<br />Connectivity!!<br />Open Connectivity makes new values for museum data<br />Connect to data in other areas<br />Connect to UGC (User Generated Contents)<br />
  37. 37. Local Information with Museum data<br />Museum LOD + Local LOD / Sightseeing LOD / Geo LOD<br />e.g., <br />Tour visiting museums with a focus<br />Joint event with local festivals<br />Tour for food related historical events<br />…<br />37<br />
  38. 38. User Generated Contents for Museum Information<br />1. Statue of Sarasvati<br />2. Ryohoji Temple<br />弁財天像<br />3. Theme Song for Ryohoji<br />4. Event<br />Contributions by non-experts<br />e.g.,<br />Personal comments for Buddha statues<br />Records of visiting museums<br />Media-mix events<br />
  39. 39. Publish museum data as LOD<br />Let’s make museum data open and shareable<br />Change “cultural heritage” to “cultural resources”<br />(art/culture) * information = Promotion of the Nation<br />Beyond collaboration of Museum Library Archives(MLA)<br />MLA3(Museum Library Archives, Arts and Academia)<br />More users, more various types of usage<br />
  40. 40. Make arts and culture more dynamic and more energetic<br />Pop Culture<br />
