Library 2.0

Library 2.0 is a model for library service that reflects a transition within the library world in the way that services are delivered to library users. This redirection will be especially evident in electronic offerings such as OPAC configuration, online library services, and an increased flow of information from the user back to the library.

With Library 2.0 library services are constantly updated and reevaluated to best serve library users. Library 2.0 also attempts to harness the library user in the design and implementation of library services by encouraging feedback and participation.

The concept of Library 2.0 borrows from that of Web 2.0, and follows some of the same philosophies underpinning that concept. Proponents of this concept expect that ultimately the Library 2.0 model for service will replace outdated, one-directional service offerings that have characterized libraries for centuries.

RSS

RSS is defined as Really Simple Syndication or Rich Site Summary.

RSS files are formed as XML files and are designed to provide content summaries of news, blogs, forums or website content.

The idea is for a feed to contain content that will be updated on a regular basis.

Sample of RSS 2.0 structure

<?xml version="1.0"?> <rss version="2.0">

<channel> <title> </title> <link><link> <description></description>

<item> <title></title> <link></link> <description> </description> </item>

</channel> </rss>

IFRAME is a HTML 4.0 Element

The IFRAME element defines an inline frame for the inclusion of external objects

An inline frame is a ”floating frame” that embeds a document into an HTML document . It is displayed inside a subwindow of the browser’s window

This does not mean full inclusion; the two documents are independent, and both of them are treated as complete documents, instead of treating one as part of the other.

Browser supportInternet Explorer version 3, Mozilla and Netscape 6 supports iframe. iCab supports it, with a user option to disable the support. WebTV Plus has iframe supportLynx 2.8.2 handles iframe in a manner similar to its treatment of normal framesOpera 4.0 supports iframe, with the option to turn the support off

”Federated searches” in your OPAC

Same method can be used to perform federated searches. Instead of just linking to a service you can fopen() it and screen scrape for result.

Then display a link with the search result displayed.

Works fine but you could run into Poxy problems

Voyager + External system = True?

ILL opac integrationCollects data from external ILL system (SAGA).

No public access

Other ideas

Import extra information like covers, toc:s etc

User tagging – stored in external database

Use AJAX
