2. What you may get out of this seminar • Fun • Intellectual stimulation • Understanding of your limits of boredom • Understanding of Linked Data • Linked Data Architecture • A source for knowledge about research activities • A source for knowledge about Linked Data identities • Why you would ask me for a sameAs store of your own • Why you would ask me to publish your Linked Data • Some insight into commercial Linked Data

3. My “Pitch” • Data Integration Technology • Breaking the Silos, both internal and external • Knowledge-Enabled Infrastructure • Businesses need to know what they know

4. Low Disruption • Can be implemented without changing the existing processes • Lower Cost • Procurement is different, which represents a challenge • Low Risk • Can be developed alongside existing solutions • Flexible • Changes can be made • Robust • Graceful degradation when services or data sources fail • Open Systems • Supplier flexibility

5. Linked Data Out There

8. A Web of Data From the Start

10. A Web of data… A Web of documents…

11. Linked Data Principles – You Know This The four micro principles of the Semantic Web 1. All entities of interest, such as information resources, real-world objects, and vocabulary terms should be identified by URI references. 2. URI references should be dereferenceable, meaning that an application can look up a URI over the HTTP protocol and retrieve RDF data about the identified resource. 3. Data should be provided using the RDF/XML syntax 4. Data should be interlinked with other data.

27. sameAs.org • Co-reference Service for the whole Web of Data • http://sameas.org/ • Over 100M Linked Data URIs (Identifiers) • URIq -> {URI1, URI2, …, URIn} • Manages multiple identifiers without making a new one • Can be enterprise-based - libraries • http://sameas.org/store/kelle

30. What is Southampton?

34. Finding Co-reference

35. Using Your Own Store

36. RKB Infrastructure • Manage all the Linked Data functions • Provide appropriate services in appropriate formats • Consumable by “normal” systems • This means • Useful – doing useful things • RESTful – easy to access • JSON – easy to process • … • http://www.rkbexplorer.com/services/ • http://www.ecs.soton.ac.uk/people/dder • http://www.dotac.info/explorer/ • http://www.rkbexplorer.com/gadgets/
