Linked Data
• HTTP URIs– Objects link to others objects
• Linked Data interface:– Object information -‐> RDF– HTTP content negotiation– RDF autodiscovery links
Where are the links?
• R&A objects:– to *entities* mentioned in annotations• entity objects: 10x more than the original objects
– to related R&A objects– to Digit. Obj. management (DOM) system URIs
• R&A annotation entities:– to R&A objects that refer to them– external links (both to RDF and HTML)

Not shown here:• Object metadata also expressed using Schema.org
RDF vocabularies used:• Bibo (Document, Letter, ...)
• Dublin Core• Schema.org
• SKOS, FOAF, ...
Let’s look at links(time for a demo?)
http://runa.lnb.lv -‐ publicly available from mid-‐June 2016
Future work:• Improved annotation tools (e.g. with typed links)• Annotating additional types of objects• Publish open data for DH researchers
Challenges:• Limited resources• Developers not familiar with Linked Data• [ Data modelling ]
Linked Digital Collection “Rainis and Aspazija”
• Rich collection, various types of content
• Object annotations – additional links between objects
• Linked Data interface– publishes open data (for reuse)– links to objects in other Linked Data systems
