Archival material specifics

• Unique & scattered material, high quantities, very diverse types of content & carriers

• Wide public (from researchers to general public – genealogists)

• Hierachical descriptions + importance of contextual information

• Legacy data issue : descriptions are a combination of structured data and semi-structured data, with sometimes consistency / quality issues

• Lack of standards for description of unique / specific material

Linked data added value

• Provide a « hub » to make it easier to locate relevant material that is scattered across several institutions

• Improve browsing experience by better linking items and allowing to discover related material

• Linking to external datasource, incl. general interest content (e.g. DBpedia) & library content (documents, authorities)

Technology pieces

• Technologies– persistent URIs for the

key entities– web pages in XHTML

containing RDFa – Linked Data RDF/XML – SPARQL endpoints

• Vocabularies– DC Terms – Bibliontology (BIBO) – FOAF – SKOS – RDFS – FRBR– & wip on

• ISAD(G)• MODS

« community » issues

• A lack of examples within particular domain (archives)

• A lack of helpful information about how to create a data model

• A certain level of expertise is important, to model data and output RDF

LLD XG F2F meeting – Pittsburgh – 2010/10/23

• Context = NDIIPP (digital preservation)– High quantities of heterogeneous material,

scattered among institutions

• Goal = enable the discovery of resources– Target = curators, librarians

• Application of Linked Data– Give URIs to every resource– Expose as Linked Data– Open source components– Enrichment with external datasets
