LODLAM Landscape NOTES

  1. 1. NISOVirtual Conference: BIBFRAME&Real World Applicationsof LinkedBibliographicData http://www.niso.org/news/events/2016/virtual_conference/jun15_virtualconf/ June 15, 2016 Keynote:Landscape andCurrentStatusof BIBFRAME and RelatedInitiatives “The LODLAMLandscape” SLIDE 1: The LODLAMLandscape Subtitle:BIBFRAME&Other LinkedDataInitiatives SLIDE 2: WhyLODLAM? First,a definition: LODLAM: linkedopen datainlibraries,archives,andmuseums Libraries – Libraries,Archives,Museums(e.g. cultural heritageinstitutions) Why isLinkedData important? Libraries – trustedrepositoriesof information;the datawe have isrich and deep Linkeddata– howwe can share that informationonthe web;makingthingsmore discoverable and accessible So what’sthe problem?!We’ve gotthisdata,sowhyisn’tit justthrownoutthere? Our data issiloedinMARC MARC  we’ve beenmakingitdosomethingitwasn’tdesignedtodofor20+ yearsnow  designedtopurelytransmitdataforprinting;NOTforbeingindexed,searched,manipulated,etc.  MARC is contextual (hello,ISBD) –machinesdon’tdocontext,theyare dumbandliteral  Henriette Avram –one of my heroes(sheroes) –BUT not a storage/retrieval format;fortransmitting and displayonly BIBFRAME isone effortto breakthat silo. SLIDE 3: Termsand Definitions Semanticweb:“W3C,"The SemanticWebprovidesacommonframeworkthatallowsdatato be shared and reused acrossapplication,enterprise,andcommunityboundaries“” Tim Berners-Lee–definedthe semanticweb/linkeddata Semanticweb is powered by Linked Data Linked Datais structured datathatis machinereadable/actionable SLIDE 4: [CATS] Of course,we all knowthe internet(akathe web) isactuallymade of aseriesof tubesfilledwithCATS, not data.

SLIDE 6: (SemanticWeb) Semanticweb – webof linkeddata powered byrules/standardsandtechnologiesthatprovide structure todata *Various(mostcommonlyused/heard)standardsandorganizationsthatpowerthe SemanticWeb;most usedas part of or bylinkeddata  W3C: WorldWide WebConsortium  URI: Uniformresource identifier(aURL is one type of URI, also have URNs)  HTTP: hypertexttransferprotocol –allowsaURI to be actionable (“linkable”or“clickable”)  XML/HTML: mark-uplanguages  Microdata: nestmetadatawithinexistingwebpage content(embeddedinHTML)  JSON:JaveScriptObjectNotation –dataformat fortransmittingdataobjects(attribute-value pairs); JSON-LD– methodof encodinglinkeddatausingJSON  RDF: Resource DescriptionFramework –conceptual descriptionormodelingof informationusedin webresources;multiple RDFspecifications(entity-relationship);mostothersemanticwebstandards are builtonor use RDF  Turtle:Terse RDF Triple Language  SPARQL:semanticquerylanguage (usesRDF);endpointforaccess  SKOS:simple knowledge organizationsystem(forcontrolledvocabularyrepresentation)  OWL: webontologylanguage (knowledgerepresentationlanguage forontologies (vocabularies/taxonomies))  FOAF:“friendof a friend”(ontologyfordescribingpersons)  Schema.org:Bing/Google/Yahoo - schemasforstructureddatamarkupon webpages SLIDE 7: (Semantic) Web:LODLAMSubset Othercommontermsand organizationswithinthe LODLAMcommunity:  BIBFRAME: data model forbibliographicdescriptionusinglinkeddataprinciples  Blacklight:discoveryinterface forSolrindex; o http://projectblacklight.org/  Solr:opensource standalone enterprise searchserver;powerful indexing o http://lucene.apache.org/solr/  Fedora:Flexible Extensible DigitalObjectRepositoryArchitecture;opensource architecture for storing,managing,andaccessingdigital contentinthe formof digital objects;
  3. 3. o http://fedora-commons.org/  Hydra: repositorysolution;“Hydraisan ecosystem of componentsthatletsinstitutionsdeploy robustand durable digital repositories(thebody) supportingmultiple “heads”:fully-featureddigital assetmanagementapplicationsandtailoredworkflows.

  4. 4.  Allowsrelationshipstohave attributes –orinformationaboutthe relationship  Assertion:one waytorepresent“trust”or “authenticate”the relationship;“who”or“what” establishedthisrelationship? ALL of the pieces of bothTRIPLES andQUADS can be URIs; any piece thatisnot a URI is a “dead-end”or literal/string SLIDE 10: LinkedOpenData[mug] Linkeddatais notguaranteedtobe OPEN;youcan have linkeddataina closednetwork However,OPEN ispreferred Why? Tim Berners-Leeprinciplesof linkeddata 1. Use URIs to name (identify) things. 2. Use HTTP URIs so that these things canbe lookedup(interpreted,"dereferenced"). 3. Provide usefulinformationaboutwhataname identifieswhenit'slookedup,usingopen standardssuch as RDF,SPARQL,etc. 4. Refertoother thingsusingtheirHTTPURI-basednameswhenpublishingdataonthe Web – e.g. linktoother URIs somore thingscan be discovered. 5. OPEN data/content But whatmakesit OPEN? OPEN data – “star” system– goal is5 stars 1. Available onthe web(whateverformat) butwith an open license, to beOpen Data 2. Available asmachine-readable structureddata(e.g.excel insteadof image scanof a table) 3. as (2) plusnon-proprietaryformat(e.g.CSV insteadof excel) 4. Use openstandardsfromW3C (RDFand SPARQL) toidentifythings,sothatpeople canpointat your stuff 5. Linkyour data to otherpeople’sdatatoprovide context Source:W3C (https://www.w3.org/DesignIssues/LinkedData.html) SLIDE 11: LinkedOpenDataCloud http://lod-cloud.net/ Aug.2014 CC-BY-SA license Representationof the LinkedOpenDatacloud – still growingasmore data setsare published Each node is a datasetthat can be queried,linkedto,andextractedfrom Centerof the hub isDBPedia connectsotherdata sources – interlinkingpublisheddatasets Upper right– codedgreen – librarydata id.loc.gov VIAF

Yes,but alsogoingbeyondMARC FocusedonRELATIONSHIPS Can lookat it as: “blowingup”a MARC recordintoits discrete elementsanddefiningtheirrelationship witheachotherand beyond(connectwithelementsnottraditionallyincluded) Classes:definearesource (underBIBFRAME) Properties:furtherdescribe aresource SLIDE 14: BIBFRAME 2.0 Model  Work – conceptual essence  Instance – embodimentof awork(one workcan have multiple instances)  Item– copyof the instance – local holdings  Agents– people,organizations,jurisdictions,etc.associatedwithawork  Subjects – “aboutness”of a work  Events– occurrences,recordingof a contentof a work SLIDE 15: All the LinkedDataActivity!
