1. The Return of the Prodigal Web Carole Goble Information Management Group The University of Manchester, UK [email_address]

2. The Return of the Prodigal Me Semantic Web E-Science (life science) Distributed Computing Hypermedia Web Accessibility

3. Hypertext? Web? Hypertext?

6. Back in the Day Or Back to the Future….

7. Xanadu: a system in which it will be possible to store anything that anybody has ever written (or photographed or filmed) that can connect any piece of information to any other piece of information Augmentation of the human intellect. “ Adequately equipped with machines which leave him free to use his primary attribute as a human being – the ability to think creatively and wisely, unencumbered by unworthy tasks – man can face an increasingly complex existence with hope, even with confidence.” “ the interaction between person and hypertext could be so intuitive that the machine-readable information space gave an accurate representation of the state of people's thoughts, interactions, and work patterns, then machine analysis could become a very powerful management tool, seeing patterns in our work and facilitating our working together through the typical problems which beset the management of large organizations.”

8. A universal medium for harvesting and harnessing collective intelligence making and using connections between decoupled content and decoupled people.

14. Open Architectures Anchor object Link object Anchor object Node Object Node Object Link Base Link Service My Favourite Application Your Favourite Application

15. Link behaviours Fluid Hypertext, Polle Zellweger, 2002

18. I’m sure Ted will tell you all about Transclusion.

20. Open Well yes…but a Closed System mentality. Come and look in MY system. Kind of assumption that content was limited and controlled Closed Authoring and Closed Architectures

21. The Web

22. TBL’s original LINK fest 1989

26. Browsers and Apps Portal Frameworks CMS & EnterpriseServers

27. DLRS circa 1998 Publishers linkbases People database Keyword linkbases Proxy Hyper link Agent XLink linkbases User profiles Person Agent Citation Agent Bibliography database IR Agent Inverted index Ontology Agent Web Browser Web Server Carr, Hughs, Hall, De Roure et al, University of Southampton, UK

29. But lets face it, its still Node-Centric There is no Link Model. Makes Context and Management Harder. Links are embedded in the Applications. Captive in their systems. No infrastructure outside the application or the browser. No Third Party Link Authoring (except shared bookmarking) User participation is Reader Participation.

30. The Parting of the Ways…

31. The Web “made riotous living”

33. Hypermedia on the Web. Versioning. Collaboration. Links. No Link Model outside the wiki.

34. Collective Intelligence

37. Web is a Platform

39. The Social Web RSS

42. Social Recommendations Collaborative, Social Tagging Collaborative, Social Bookmarking Content Sharing Application Execution

43. Tags New Content New Capability

46. Tagging and Aggregating

48. What’s this got to do with Hypermedia? The Social Writing sharing of content and links. The Infrastructure for Dynamic Hypertext. Content syndication IS computation in the Hypertext. Mash-ups ARE composite hypermedia nodes. The Return to Reuse. Link behaviour in the browser. Two way linking in wikis and blogs. Link types by microformats. Javascript Libraries for multi-headed links etc.

49. Web 2.0 Microformats AJAX, JSON Tagging CSS, XSLT XPointer, XML Web 2.0 REST, Tagging RSS, ATOM, APIs OpenID, Identity 2.0 Ruby on Rails
