BrowseRDF.com allows you to navigate arbitrary RDF datasets using an exploration technique called "faceted browsing". This technique lets you easily navigate through unfamiliar datasets.

Your Home for Faceted Classification Tools Facetmap is both a data model and a software package, created to let users browse complex metadata while retaining a simple, familiar, menu interface.

MarkMail is a free service for searching mailing list archives, with huge advantages over traditional search engines. It is powered by MarkLogic Server: Each email is stored internally as an XML document, and accessed using XQuery. All searches, faceted navigation, analytic calculations, and HTML page renderings are performed by a small MarkLogic Server cluster running against millions of messages.

XFML lets you exchange hierarchical faceted metadata. It also lets you indicate topics in different published XFML documents are equal, thus allowing you to reuse indexing efforts. XFML borrows many ideas from Topicmaps, a format you should check out if you like the ideas behind XFML but are frustrated with its limitations (see http://topicmaps.org).

The Flamenco search interface framework has the primary design goal of allowing users to move through large information spaces in a flexible manner without feeling lost. A key property of the interface is the explicit exposure of category metadata, to guide the user toward possible choices, and to organize the results of keyword searches. The interface uses hierarchical faceted metadata in a manner that allows users to both refine and expand the current query, while maintaining a consistent representation of the collection's structure. This use of metadata is integrated with free-text search, allowing the user to follow links, then add search terms, then follow more links, without interrupting the interaction flow.

This text sets out a series of approaches to the analysis and synthesis of the World Wide Web, and other web-like information structures. A comprehensive set of research questions is outlined, together with a sub-disciplinary breakdown, emphasising the multi-faceted nature of the Web, and the multi-disciplinary nature of its study and development. These questions and approaches together set out an agenda for Web Science, the science of decentralised information systems. Web Science is required both as a way to understand the Web, and as a way to focus its development on key communicational and representational requirements. The text surveys central engineering issues, such as the development of the Semantic Web, Web services and P2P. Analytic approaches to discover the Web's topology, or its graph-like structures, are examined. Finally, the Web as a technology is essentially socially embedded; therefore various issues and requirements for Web use and governance are also reviewed.

/facet is a generic browser for heterogeneous semantic web repositories. The browser works on any RDFS dataset without any additional configuration.

One facet of modeling wildlife-habitat relations and species-environment relations may pertain to depicting the ecological roles played by organisms. I have termed these "key ecological functions" or KEFs.

A new Species-Environment Relations (SER) modeling approach depicts key ecological functions (KEFs) and key environmental correlates (KECs) of terrestrial plant and animal species, as part of a regional assessment of the Interior Columbia Basin Ecosystem Management Project. Assessing KEFs of species is one facet of understanding management effects and ecological integrity of ecosystems. A relational database was developed that ties species' KEFs with their key habitats, KECs, and distribution maps. In this way, potential management activities can be evaluated for how they influence: habitats and environmental correlates; associated plant, invertebrate, and vertebrate species; the array of ecological functions associated with those species; geographic functional ecology; and potential effects on ecosystem productivity, diversity, and sustainability.

Longwell mixes the flexibility of the RDF data model with the effectiveness of the faceted browsing UI paradigm and enables you to visualize and browse any arbitrarely complex RDF dataset, allowing you to build a user-friendly web site out of your data within minutes and without requiring any code at all.
