LOCAH - Linked Open Copac Archives Hub

• Archives Hub: Finding aids from over 200 Institutions in the UK

• JISC Project to model EAD as RDF

• Well-modeled, structured data enables innovative uses Timelines Visualizations Discoverability

All these innovations rely on the data

that comes in

“utilising external datasets in order to bring archives together with other data sources”

“there is still a need to make a convincing argument that Linked Data really will provide concrete benefits to the end user.”
