Technologies (First Session)
• Lucene/Solr• XML• RSS and Atom• AJAX• LAMP• OpenID
Concepts (First Session)
• Web 2.0 / Library 2.0• Social software• Extensible software• Feeds• New “standard” for discovery
tools
Demonstrations (First Session)
• Web feeds• Open source ILS systems• New discovery systems based on
Lucene/Solr
Web 2.0 / Library 2.0
• Tim O’Reilly (of the computer book publisher O’Reilly & Associates) has been an articulate spokesperson– What Is Web 2.0
http://www.oreillynet.com/lpt/a/6228
• May incorporate new technologies but more reflects an approach to services than a technology
Tim O’Reilly’s Six Big Ideas
1. Individual production and user generated content
2. Harness the power of the crowd3. Data on an epic scale4. Architecture of participation5. Network effects6. Openness
2.0 Characteristics
• Interactivity• Profile-based customized
experiences• Ability to self publish or collaborate• Ratings, reviews, comments, tagging• Standards-based distribution formats
that allow reuse or reformatting (XML)
2.0 Technologies
• XML• AJAX (Asynchronous JavaScript and
XML)– Cascading style sheets– XML
• LAMP (Linux, Apache, MySQL, and Perl or Python)
• Web loads software not simply pages, the Web is a software platform
• In this approach some of the processing is shifted to the client
2.0 Approaches
• More decentralized and trusting of users– Wikis– Blogs
• More finely tuned by the user– RSS– Firefox
• Mash-ups– Combining different sources into one – Data typically in some XML format
• Social bookmarking and tagging
Tagging
• Process of assigning descriptive keywords or phrases to a online record (such as a web page in a social bookmarking system, a photographic description, or a blog entry) in order to aid in organization or retrieval
• Collective tagging can produce a folksonomy
• A word cloud is the representation of a set of tags assigned to a given web page or record by a group of people, a piece of a folksonomy
Demonstration
• Furlhttp://www.furl.net
• Flickrhttp://www.flickr.com
• Digghttp://www.digg.com
• LibraryThinghttp://www.librarything.com
• Firefox add-onshttps://addons.mozilla.org/firefox/extensions/
The Long Tail
• Notion that those in the tail of a statistical graph total more than those in the main curve
• By using the net, unique needs can be met and marketed more than “average” needs
• Amazon sells more books not typically carried by bookstores than books that are carried--meeting the needs of the long tail
Wikinomics
• Idea that business is going through a huge change right now that is driven by Web 2.0 technologies and approaches and the mass collaboration that they foster.
• Don Tapscott, one of the inventors of this term believes that mass collaboration is going to fundamentally change how corporations operate.
The Cluetrain Manifesto
• This weird and wonderful document argues that companies need to change how they communicate and market themselves because of the changes in how people are communicating online, particularly in blogs.
Web 2.0 Bottom Line
• Pros– The interactivity and social aspects
are very attractive to users– The customized experience may
better meet users needs• Cons
– It requires a much more sophisticated tool kit to build this house
But…
It’s where the users are.
So…
It’s where we need to be.
New Standard for Discovery Tools
• The new “standard” feature set includes:– Faceted searching– Ranked retrieval– Spell checking
• “Did you mean…”– RSS feed of search results– Book covers– Reviews– FRBR (minimally, collated editions)– Commenting
• Optional, but coming:– Tagging– Rating
Software
• NCSU’s Endeca-based system• Open source ILS advances
– Evergreen– Koha indexing update with Zebra (3.0)
• Open source indexing and discovery tools– Lucene/Solr/Flare
• Commercial discovery tools– AquaBrowser– Encore, Primo, Visualizer, etc.
Solr
• Standalone enterprise search server• Full-Text Search• Standards Based Open Interfaces• Optimized for High Volume
– XML– HTTP
• HTML Administration Interface• Scalable• XML configuration • Extensible Plug-in Architecture
So What?
•Casey Durfee of Seattle Public Library demonstrated how you can create a new discovery tool using Lucene/Solr with just over 250 lines of code
• This technology is accessible!

Web Feeds
• RSS and Atom are types of web feeds• A web feed is a data format used for
serving users frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation. -- Wikipedia
RSS
• Depending on the version, RSS means– Really Simple Syndication– Rich Site Summary– RDF Site Summary
• The most recent standard is RSS 2.0
Atom
• The name Atom applies to a pair of related standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol (APP for short) is a simple HTTP-based protocol for creating and updating Web resources-- Wikipedia
• Atom feeds have come into wide usage in part because of Google’s decision to use the format for all their feeds
XML
• XML (eXtensible Markup Language) is a general purpose markup language based on SGML (just like HTML) which is used to create RSS feeds among many other things
Library-related XML Schemas
• MARCXML - MARC 21 data• MODS (Metadata Object Description Standard)
- Selected metadata from existing MARC 21 records as well as original resource description
• MADS (Metadata Authority Description Standard) - Selected authority data from MARC21 records as well as original authority data
• EAD (Encoded Archival Description) - For finding aids
• METS (Metadata Encoding & Transmission Standard) - For encoding descriptive, administrative, and structural metadata
• MIX (NISO Metadata for Images in XML) - For encoding technical data elements required to manage digital image collections
OPML
• Outline Processor Markup Language (OPML) is an XML format for outlines, now used for lists of feeds
• OPML is most often used to import and export lists of subscriptions (feeds) between readers
Definitions
• Atomhttp://en.wikipedia.org/wiki/Atom_%28standard%29
• OPMLhttp://en.wikipedia.org/wiki/OPML
• RSShttp://en.wikipedia.org/wiki/RSS_%28file_format%29
• XMLhttp://en.wikipedia.org/wiki/XML
• Web Feedhttp://en.wikipedia.org/wiki/Web_feed
Specifications
• RSS 2.0 (Harvard)http://blogs.law.harvard.edu/tech/rss
• Atom 1.0 (IETF)http://tools.ietf.org/html/rfc4287http://atompub.org/rfc4287.html
Don’t PANIC!
It’s easier done than said…
You don’t have to learn XML to produce feeds!
Aggregators
• Software for viewing feeds• Three common forms:
– Web browser plug-in or extension
– Web-based service– Stand-alone application
Firefox (Browser)
Google Reader (Web-based)
KlipFolio (Stand-alone)
JetBrains Omea Reader (Stand-alone)
RSS and Atom Feeds Bottom Line
• Pros– Standards based– Spam free syndication– Allows users the freedom to reformat
or reuse• Cons
– Competing standards may confuse some
– Publisher has no control over display
Privacy and Libraries
• Who owns the content?– Tim O’Reilly
• Students posting material they might regret later in live
• Need for privacy policies that address user-generated content– Lauren Gelman
• Multiple personas online• Third party storage of profile data
Homework
• Discussion question for next session– What privacy issues are raised by the
shift towards the use of social software in libraries?
• Try searching in– http://www.technorati.com/– http://www.bloglines.com– http://blogsearch.google.com
End of Part One
Exercise
• Discussion question for next part– What privacy issues are raised by the
shift towards the use of social software in libraries?

Concepts (Second Session)
• Blogging• Podcasting• Mass Collaboration• Mash-ups
Demonstrations (Second Session)
• Blog search engines– Bloglines– Google Reader– Technorati
• Podcasting• Wikis
– PLN– Library Success Wiki
Blogs
• A blog is a series of web-based articles, sometimes a journal, which is organized chronologically (the word blog is derived from weblog, a log of comments on the Web)
• Some blogs encourage wide-participation
• Many Blogs are set up as feeds, using RSS or Atom
More on Blogs
• Blogs are a social phenomenon as much as technical
• Precise definition is elusive--in essence, any web-based discussion is a blog
• Think of blogs as ongoing conversations, many are diaries and involve very controversial topics
• Most solicit responses from readers
Library-related Blogs
• There are now many library-related blogs
• Many professional discussions have largely moved from the e-mail list forums to blogs
Blog Example
Finding Feeds
• They are everywhere• Look for the feed symbol
in a web page or next to the location box in your browser
• Click to subscribe
ProQuest and EBSCO RSS
Feeds and Blogs in Libraries
• Patron overdue notifications (Seattle Public Library)
• New title notifications (Seattle, Ann Arbor, Penn)
• Notification to students in library instruction (Philadelphia University)
• RSS implemented or planned for variety of ILS services
Creating Blogs & Feeds
• For feeds, write files in pure code• Use software to create a feed, e.g.
ListGarden, RSS Publisher, and Feed for All
• Most blog programs generate RSS feeds, such as Bloglines
• Can create blogs with Blogger, WordPress, MovableType
Blogs Bottom Line
• Pros– Great way for libraries to speak in a human
voice– Participation of individual librarians can
attract and hold customers when they have a positive experience
– Democratizing effect• Cons
– The proliferation of personal blogs may make it hard for an organization to speak with one voice (market)
Demonstration
• Bloglines– Subscribing to a blog search feed
Blogs Bottom Line
• Pros– Great way to give a human voice to your
organization– Enhances and encourages communication
• Cons– Need to set guidelines for what is
appropriate content, if the organization’s name is associated with the blog
– Can make it hard to control the marketing message
Podcasting
• Digital sound files- format is frequently MP3 or OGG VORBIS
• Files can be played on most laptops, many PDAs, and the Apple iPod (where the “pod” in podcasting is derived)
• Typically, a podcast is distributed on the Internet via Internet feed technology such as RSS
Podcatchers
• The aggregators to obtain podcasts are sometimes called podcatchers
• Apple iTunes, available for free for Windows and Mac machines, is a podcatcher http://www.apple.com/itunes/download/
• iPodder is another podcatcherhttp://www.ipodder.org/directory/4/ipodderSoftware
Finding Podcasts
• Podcast directories:
– PodcastAlley.comhttp://www.podcastalley.com/
– Podcast.nethttp://www.podcast.net/
– iPodder.orghttp://ipodder.org
Podcasting Requirements
• Personal computer• Microphone
– Blue Snowballhttp://www.bluemic.com/modules.php?op=modload&name=Products&file=index&prod_id=18
• Software that can create MP3 or OGG Vorbis files– Audacity
http://audacity.sourceforge.net/• Web server on which to place the sound
file• Ability to create an RSS feed
Demonstration
• Podcast creation
Podcasting in Libraries
• PALINET has podcasts http://http://blog.palinet.org/podcast
• Librivox is a huge effort to provide sound files for public domain books http://www.librivox.org/
• Lansing MI public library has several podcasts of tech news, info teens, and also for children http://www.lansing.lib.il.us/podcast.htm
Podcasts Bottom Line
• Pros– Format allows customers to consume
information when and where it is most convenient for them
• Cons– Requires hardware (iPod or MP3
player)– Apple iPods don’t support MP3 files
directly– Apple iTunes only open to iPods
Wikis
• Pronounced as wick-ey (rhymes with sticky) or wee kee (rhymes with we key)
• Wiki is part of Hawaiian word for quick (wiki-wiki)
• Invented by Ward Cunningham to help develop Web pages quickly
Content Management System
• Pages editable via the web• Content stored in a database• Logs changes• Stores previous versions• Allows you to compare versions• Allows rollback to a previous
version
Social Software
• It forms a space for both collaboration and self-publishing
• Comments and discussion are encouraged
• Many wikis also support blogging, discussion forums, and other structured content
What’s a Wiki Good For?
• Getting rid of bottlenecks• Maintaining information that
changes frequently• Improving discovery• Preservation of ephemeral data
Getting Rid of Bottlenecks
• Allows you to push the responsibility for posting information on the website out to the owner of information
• Allows anyone who has the useful input to post
• Encourages a sense of community and of ownership
• Encourages collaboration
Maintaining Frequently Changing Information
•Editing is very quick and easy
•No HTML required (but some supported)
•Shallow learning curve
Improving Discovery
• Everything is automatically indexed and searchable
• Navigational tools allow for easy discovery of new or changed data– Watches– New page lists– Changed page lists
Preservation of Ephemeral Data
• All content is stored in a database
• All previous versions are stored
• Deleted pages can be recovered– Nothing is ever lost
Demonstration
• Library Wikis
Wikis Bottom Line
• Pros– Easy way to collaboration– Wisdom of the crowds– Low cost web development tool
• Cons– No (real-time) central control over
content– Content may not be reliable– Still some training required
