  2. 2. 2011 - Web Interoperability is broken<br /><ul><li>APIs:
  3. 3. Too many of them
  4. 4. Not aware of each other
  5. 5. APIs Operate on the keyword level
  6. 6. No standard ontology
  7. 7. Different formats
  8. 8. TOS/rate limits /credibility are notmachine readable
  9. 9. Discovery doesn’t exist (WSDL failed)
  10. 10. Too few know RDF/OWL/SPARQL
  11. 11. 99.9% of the information on the web is free form text
  12. 12. Web data is partial, noisy, inaccurate, not objective</li></li></ul><li>Abstraction stack - towards data aware apps<br />
