Metadata is data about data. Specifically, the term refers to data used to identify, describe, or locate information resources, whether these resources are physical or electronic. While structured metadata processed by computers is relatively new, the basic concept of metadata has been used for many years in helping manage and use large collections of information. Library card catalogs are a familiar example of such metadata.

        <dc:creator>Eric J. Miller</dc:creator>
        <dc:description>The Resource Description Framework (RDF) is an
         infrastructure that enables the encoding, exchange and reuse of
         structured metadata. rdf is an application of xml that imposes needed
         structural constraints to provide unambiguous methods of expressing
         semantics. rdf additionally provides a means for publishing both
         human-readable and machine-processable vocabularies designed to
         encourage the reuse and extension of metadata semantics among
         disparate information communities. the structural constraints rdf
         imposes to support the consistent encoding and exchange of
         standardized metadata provides for the interchangeability of separate
         packages of metadata defined by different resource description
         communities. </dc:description>

information repository

The Web is becoming a universal repository of human knowledge and culture, which has allowed unprecedented sharing of ideas and information in a scale never seen before.

browsing & navigation

To satisfy his information need, the user might navigate the hyperspace of web links searching for information of interest. However, since the hyperspace is vast and almost unknown, such a navigation task is usually inefficient.

information agent

gather information
filter and select

presentation agent

PERSONAS

investigating a new approach to navigation through information spaces, based on a personalised and social navigational paradigm.

Agneta & Frieda

The AGNETA & FRIDA system seeks to integrate web-browsing and narrative into a joint mode. Below the browser window (on the desktop) are placed two female characters, sitting in their livingroom chairs, watching the browser during the session (more or less like watching television). Agneta and Frida (mother and daughter) physically react, comment, make ironic remarks about and develop stories around the information presented in the browser (primarily to each other), but are also sensitive to what the navigator is doing and possible malfunctions of the browser or server.

Agneta & Frieda

In this way they seek to attach emotional, comical or anecdotal connotations to the information and happenings in the browsing session. Through an activity slider, the navigator can decide on how active she wants the characters to be, depending on the purpose of the browsing session (serious information seeking, wayfinding, exploration or entertainment browsing).
