3. Introduction “Keeping Found things Found” – need for locating and organizing findings. “Keeping Found things Found” – need for locating and organizing findings. Information Filtering Information Filtering  Deals with unstructured and semi-structured data.  Focus upon users long term or repeated interests.  Paths or trails – access to subset of information. Maintaining Collections Maintaining Collections  User patterns of storing relations correlates to patterns of seeking information. Interconnected path structure – maintains several layers of interrelationships between materials simultaneously. Interconnected path structure – maintains several layers of interrelationships between materials simultaneously.

4. Syndication of Web Content Web syndication Web syndication  Making web feeds available from a site with a summary of websites recently added content. Feed – a data format to publish frequently updated content. Feed – a data format to publish frequently updated content. Linear paths arranged in chronological sequence Linear paths arranged in chronological sequence Imports the contents of feeds into path browsing system to create meta collections linking together web pages. Imports the contents of feeds into path browsing system to create meta collections linking together web pages.

5. System – Walden Path Walden paths Walden paths  Suite of tools to create, present and maintain linear interconnected paths.  Paths provide metadata –Annotations –Human ordering –A structure atop of existing web pages.  Basic unit of information – stop (references to a webpage via a URL).
