Data Rules Deep indexing:
Amazon’s “Search Inside” and “Statistically Improbable Phrases”
Google, Yahoo, Microsoft underwriting library digitization work Library space: NetLibrary & many others indexing content Custom search feeds: Google Alerts, News topic RSS, etc.
Recommendation systems: Amazon, Apple iTunes, other retailers – “people like you
chose…” Novel concepts: Pandora – suggests music based on intrinsic
patterns of music you like (the “music genome”)

Techscape Web 2.0:
The Network spans all attached devices (e.g., iPods, phones, etc.)
Software resides on the Net, not the workstation “Participative Net” – social environment, shared content
reused System refactoring
Modularity (micro-services, remixing, multiple sources) Layering (loosely-coupled systems) Interoperability (low-friction, high reuse)
Lightweight protocols gaining favor (e.g., SRW/SRU, microformats) Machine-oriented services (web services)

Libraries - next phase Surfacing seamlessly
Point-of-need delivery (e.g., library content in non-library apps such as the Web, course management systems, etc.)
Open WorldCat, RedLightGreen, OAIster, etc.
Open standards, easy integration of data from many sources Re-thinking, re-engineering
Library 2.0 changes systems & services Moving towards “Lego”-like modularity in systems & data User-tasks-oriented designs (e.g., NCSU catalog) Adding means for users to contribute, shape their own experiences
Supporting Library 2.0 will mean changing organizations & operations More building space for people-to-people interaction, less for books Process & operational changes
Example: Choose-acquire-catalog vs. Acquire-choose-catalog

Technology to watch
Model: FRBR (Functional Requirements of Bibliographic
Records)
Approach: Loosely-coupled applications AJAX
OCLC ResearchOCLC Online Computer Library Center
“The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected data, enabling the user to perform seamlessly all the necessary functions.”
-Dr. Maja Žumer. National and University Library, Ljubljana, Slovenia
OCLC ResearchOCLC Online Computer Library Center
FRBR basics FRBR = Functional Requirements for Bibliographic
Records Developed by cataloging experts working under the
auspices of IFLA (International Federation of Library Associations and Institutions)
FRBR is from a document issued by IFLA: Functional Requirements For Bibliographic Records:
Final Report (1998) FRBR is a conceptual model (not a standard!)
FRBR systematically models the bibliographic universe

Sample AJAX implementation
OCLC ResearchOCLC Online Computer Library Center
AjaxStands in for “Asynchronous JavaScript+CSS+DOM+XMLHttpRequest”Eliminates the start-stop-start-stop nature of interaction on the Web by introducing an intermediary — an Ajax engine — between the user and the serverBeing used extensively by Google, adopted by others
Technolgies used together:standards-based presentation using XHTML and CSSdynamic display and interaction using the Document Object Modeldata interchange and manipulation using XML and XSLTasynchronous data retrieval using XMLHttpRequestand JavaScript binding everything together.
