– Audio / video
http://runa.lnb.lv

6. Poets' correspondence
• 35 years of letters between Rainis & Aspazija
• ... covering important stages of Latvian history
and cultural development
• ... included in the Latvian register of the
UNESCO “Memory of the World” program.
Note: the pilot project contains a subset of
early correspondence between the poets.

8. *Linked* Digital Collection
• Let's add links!
– Between collection objects and the entities
[somehow] related to them
• Named entity annotations
– Letters = transcribed & with expert comments
– Marked mentions of all entities that could be
identified in text (manual annotation)
– Entity information (pages) added to the collection

12. Linked Data
• HTTP URIs
– Objects link to others objects
• Linked Data interface:
– Object information -> RDF
– HTTP content negotiation
– RDF autodiscovery links

13. Where are the links?
• from 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
• from R&A annotation entities:
– to R&A objects that refer to them
– external links (both to RDF and HTML)
