8. Linked open data as the original web Semantic web enables a linked open data web
10. Bottom line The more data being provided and made available to the public as OPEN, LINKED and accessible with semantically defined content.. …the smarter our applications can be.. Source: http://www.readwriteweb.com/archives/open_data_linked_data_semantic_web.php
15. The challenge with hierarchies and classification People look for patterns Interpretation has always been difficult As always – people are different and as situations change, context changes
16. How about… Don’t put data into tight boxes that are hard to reach down into and drag something out of… the coat most often gets wrinkled… A triangle doesn’t fit in a round hole.. And create a nice pair of shaded sunglasses for the data set to wear at appropriate occations…?
17. 17 Linked open data offers a dynamic set of facets LOD is a line of principles to align data manypair of glasses to look at the material An architecture presented like ONE archive

37. Mashups, APIs andlinked open data – They do not work with clients that have not been designed with the specificAPI in mind. – Their content cannot be accessed by search engines and other generic web agents. – Each mashup only allows access to data from a limited number of sources chosen by the developer. In contrast, information on the Semantic Web can be used by generic clients, including RDF browsers, RDF search engines, and web query agents.

…how many of you have made use of social media, Google and multiple other sources in their work to dig for more information and how many times you have thought…OH, I wish i could see these connections between this and this and this and that without searching everywhere and drawing my own mindmap…!
