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)

Let’s look at links(time for a demo?)

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
