TRANSCRIPT

  • Aligning library-domain metadata with the Europeana Data Model Sally CHAMBERSValentine CHARLESELAG 2011, Prague

  • Presentation outline The library domain landscapeThe Europeana Data Model (EDM)How libraries can benefit from EDM?Future steps

  • The library landscape

  • The Europeana Data Model (EDM): An initiative from:

    A digital library that is a single, direct and multilingual access point to the European cultural heritage. European Parliament, 27 September 2007

    A unique resource for Europe's distributed cultural heritage ensuring a common access to Europe's libraries, archives and museums.Horst Forster, Director, Digital Content & Cognitive Systems Information Society Directorate, European Commission

  • The Europeana Data Model (EDM): in collaboration with the libraries domain The European Library is a portal offering access tothe bibliographic, digital and full-text resources ofthe 49 national libraries of Europe in 35 languages.

  • The Europeana Data Model (EDM): in collaboration with the library-domain

  • Now: the Europeana Semantic Elements (ESE) Europeana Semantic Elements (ESE) developed for the prototype (now on v3.4)

    A Dublin core-based application profileCross-domain schema for heterogeneous dataNot to capture the full semantics of providers data

    37 Dublin Core terms to describe the objectsfor search and display

    14 Europeana terms - used to support portal functionalitiesElements to be added by providersElements added internally by the Europeana ingestion team

  • Now: the Europeana Semantic Elements (ESE)

  • The rationale behind EDM

  • The rationale behind EDM: principles

  • The rationale behind EDM: requirements1. Distinction between provided object (painting, book,program) and digital representation2. Distinction between object and metadata record describing an object .3. Allow for multiple records for same object, containingpotentially contradictory statements about an object4. Support for objects that are composed of other objects5. Standard metadata format that can be specialized6. Standard vocabulary format that can be specialized7. EDM should be based on existing standards

  • The general picture: where are the libraries?

  • skos:exactMatchThe general picture: where are the libraries?

  • EuropeanaThe general picture: where are the libraries?

  • What is EDM? Based on an open, cross-domain semantic web-based frameworkEDM has been specified with an RDF model

    It uses Dublin Core for metadata representationSpecialization of 15 original DC elementsAnd for backward compatibility, cf. ESECan be specialized itselfUsed in the richest way possible: Pointers to resources

    OAI-ORE for organisation of metadata about an object

    SKOS for vocabulary organisation

  • EDM: main notions EDM allows the distinctinction between: an object: which is the resource being described a digital representation: digital form of the object with a Web address

    These two information form an Aggregation organizes object information from a particular provider (museum, archive, library)

  • The structure of the model: classes A group of things that have common properties e.g. web resources.

  • The structure of the model: properties (without ESE properties)An attribute or characteristic of a resource e.g. a member of the class Agent will have the property of Name.

  • Our example

  • One record in oai_dc format

  • Properties for the provided cultural heritage object (ens:ProvidedCHO)This means that they are the attributes of the source cultural heritage object itself, not the digital representation of it.

  • Properties for the provided cultural heritage object (ens:ProvidedCHO)

  • Properties for the Web Resource (ens:WebResource) Information Resources that have at least one Web Representation and at least a URI.

  • Properties for the Web Resource (ens:WebResource)

  • The structure of the model: classes

  • Properties for the aggregation (ore:Aggregation)The set of resources related to a single cultural heritage object that collectively represent that object in Europeana. Such set consists of: all descriptions about the object that Europeana collects from (possibly different) content providers, including thumbnails and other forms of abstractions, as well as of the description of the object Europeana builds.

  • Properties for the aggregation (ore:Aggregation)

  • Contextual resources (Place, Time, Agent, Concept) These classes are used to produce enriched descriptions, especially when controlled vocabularies are existing and used by institutions

    for instance ens:Agent

  • Contextual resources (Place, Time, Agent, Concept)

  • The structure of the model: classes

  • The structure of the model: properties (without ESE properties)

  • Europeana as a distinct metadata provider Europeana is: taking data from multiple providerswhich may be about the same resourcegiving multiple views on the same resourceadding its own data about a resource (enrichment)

    The notion of proxy: specific to a given provider represent the description of the provided object as seen from the perspective of that specific provider.

  • Europeana as a distinct metadata provider

  • How libraries can benefit from EDM?

    EDM allows a richer resource discoveryImproves visualisation of complex data Enrichs data through the creation of new associations between both search terms and metadataFacilitates libraries participation to the Semantic Web Transcends domain-specific metadata standards

  • Preserves the richness of original data Our example: a second record in EAD

  • Representation of two resources packages

  • Allows a better (re)presentation of complex objects

  • Beyond metadata: full-text content

  • Future stepsUnderstand the Europeana Data ModelExplore how we can apply the Europeana Data Model to library metadataValidate the draft Europeana Data Model for libraries with real-world metadataImplement the Europeana Data Model for libraries with metadata from national, university and public librariesCreate library-specific documentation and training materials
