  1. A framework for Linked Data business models MichalisVafopoulos vafopoulos.org 1/10/2011

  2. Main issue Web of data: • What is and Why is useful • How can be sustainable?

  3. Outline • The Web of documents vs. Web of data • Linked Data Principles • Web science perspective • Why Linked Data • It is the economy stupid! • Network externalities in the Web • Network externalities in Linked Data • A framework for Linked Data Business

  4. The Web of Documents • Simple, big and unstructured • Organized in Silos But humans: • are interested in Things, no documents & these Things might be in docs or elsewhere • Limited capacity to extract meaning...

  5. The Web of Data • Analogy:a global filesystem----> globaldatabase • Designed for: human consumption ->machines first, humans later • Primary objects: documents --> things (or descriptions of things) • Links between: documents--> things • Degree of structure in objects: fairly low ---> high • Semantics of content and links: implicit --> explicit (Tom Heath)

  6. Linked Data Principles • Use URIs as names for things • Use URIs so that people can look up (dereference) those names • When someone looks up a URI, provide useful information • Include links to other URIs so that they can discover more things

  7. The Web of Data: why? • encourages reuse • reduces redundancy • maximizes its (real and potential) inter-connectedness • enables network effects to add value to data

  9. Two magics of Web Science: the case of Linked Data

  10. It is the economy stupid! • Network externalities: • network goods • indirect effects of consumption/production • effects on agents not the originator • outside the price system • Positive, e.g. find information • Negative, e.g. receive spam

  11. Network externalities in the Web • fundamental source of value • Web 1.0: links among documents • Web 2.0: links among Users and their contribution • Web 3.0: links among structured data

  12. Network externalities in Linked Data Building bidirectional and massively processable interconnections among online data Linked Data as an enabler for existing infrastructures

  13. A framework for Linked Data Business models Value Proposition what value the business creates Product/Services which service and to whom Architecture how the value is created Revenue Model sources and types of income

  14. issues • Incorporate in Web 2.0 (transition) • Key issue for many business • Do not worry about Google! • Standalone data or LD services? • Privacy becomes an issue • LD services to control your personal LD flow? • …

  15. overview Web of data: • What is and Why is useful • How can be sustainable? Questions?

  17. the 5 stars of open linked data ★make your stuff available on the Web (whatever format) ★★make it available as structured data (e.g. excel instead of image scan of a table) ★★★non-proprietary format (e.g. csv instead of excel) ★★★★use URLs to identify things, so that people can point at your stuff ★★★★★link your data to other people’s data to provide context http://lab.linkeddata.deri.ie/2010/star-scheme-by-example/
