Faceted Classification: How-To

How to Make a Faceted Classification and Put It On the Web

Faceted classifications are increasingly common on the World Wide Web, especially on commercial web sites (Adkisson 2003). This is not surprising--facets are a natural way of organizing things. Many web designers have probably rediscovered them independently by asking, "What other ways would people want to view this data? What's another way to slice it?" A survey of the literature on applying facets on the web (Denton 2003) shows that librarians think it a good idea but are unsure how to do it, while the web people who are already doing it are often unaware of S.R. Ranganathan, the Classification Research Group, and the decades of history behind facets.

This paper will attempt to bridge the gap by giving procedures and advice on all the steps involved in making a faceted classification and putting it on the web. Web people will benefit by having a rigorous seven-step process to follow for creating faceted classifications, and librarians will benefit by understanding how to store such a classification on a computer and make it available on the web. The paper is meant for both webmasters and information architects who do not know a lot about library and information science, and librarians who do not know a lot about building databases and web sites. The classifications are meant for small or medium-sized sets of things, meant to go on public or private web sites, when there is a need to organize items for which no existing classification will do. It is certainly not the intent of this paper to show how to build another universal classification, nor to describe how a library that uses a faceted classification scheme can put their catalogue online.
