13 Wikis A wiki is a freely-expandable collection of interlinked Web 'pages, a hypertext system for storing and modifying information - a database, where each page is easily editable by any user. (Leuf and Cunningham 2001, 14) Wikis in Plain English (3 52 video) Slide 13

15 RSS Feeds Feeds are documents used to transfer frequently updated digital content to users. This content ranges from news items, weblog entries, installments of podcasts, and virtually any content that can be parceled out in discrete units. You syndicate, or publish, content by producing a feed to distribute it. You subscribe to a feed by reading it and using it. You aggregate feeds by combining feeds from multiple sources.

30 Web Library = Library 2.0 (Miller, 2005) Library 2.0 reflects a transition within the library world in the way that services are delivered to users. Library 2.0 attempts to harness the library user in the design and implementation of library services by encouraging feedback and participation. The Library 2.0 model offers bi-directional service and increases flow of information from the user back to the library. Source: Slide 30

33 Web 2.0 in Library 2.0 Diffusion Concentration Lorcan Dempsey s blog: Slide 33

34 Diffusion covers a range of tools and techniques which create richer connectivity between people, applications and data; support writers as well as readers; provide richer presentation environments; blogs and wikis; RSS; social networking; crowdsourcing of content; websites made programmable through web services and simple APIs; simple service composition environments; Ajax, flex, silverlight; and so on; Much of the library discussion of Web 2.0 is about 'diffusion', about a set of techniques for richer interaction. It is appropriate that libraries should offer an experience that is continuous with how people experience the web. Source: Slide 34

35 Concentration Involves major gravitational hubs (google, amazon, flickr, facebook, propertyfinder.com). Concentrates data, users (as providers and consumers), and communications and computational capacity. They build value by collaboratively sourcing the creation of powerful data assets with their users. The value grows with the reinforcing property of network effects: the more people who participate, the more valuable they become. And opening up these platforms through web services creates more network effects. These sites also mobilize usage data to reflexively adapt their services, to better target particular users or to identify design directions. Source: Slide 35

36 Library management environment Places where data needs to be concentrated to create value: aggregating user data across sites (e.g. counter data), or aggregating user created data (tags, reviews), or aggregating transactions (e.g. circulations, resolver clickthroughs). Motivations here are to drive business intelligence which allows services to be refined (e.g. how does my database usage compare to that of my peer group), to develop targeted services (people who like this, also liked that), to improve local services (e.g. add tags or reviews). These are examples where scale matters, where data may need to be concentrated above the individual library level. Source: Slide 36
