I'm sorry I had to remove your Yahoo! example from Colon Classification. CC isn't a general term for faceted classifications and the use of colons or whatever punctuation doesn't make any classification a faceted one. The page probably isn't at its current state clear enough about this. Yahoo! directory seems to use a normal hierarchical classification, but I'm not completely sure. Do you know if it is a real faceted classification? Wipe 07:01, 24 May 2005 (UTC)
No, Yahoo! is not an example of Colon Classification, as you'll probably notice if you read that article you cited thoroughly. The author tries to find similarities between Yahoo!'s classification scheme and Ranganathan's Colon Classification, which is a complex and well defined system with specific rules. Colon Classification is a faceted classification scheme, but there are others. Nothing convinces me that Yahoo! uses one. Indeed, the author of the article somewhat fails in her attempt to show the similarities.
"Once at 'Education: Higher Education: Colleges and Universities' the next link for the geographic subcategory ('United States@') actually drops me back into the Regional hierarchy, as noted initially."
That's not proper faceted classification! The article she's seeking is only in one place (or class). Most likely the hierarchy tree of classes repeats certain "facets" in its structure, such as a class named "Colleges and Universities" under every single "Education" class under each "Cities" class. A faceted classification on the other hand would give each article a description of it's own based on some predetermined aspects (facets) such as place, time, and nature. The information seeker would not have to jump from class to class when browsing the directory. They would just give a value to as many facets as necessary and they would be presented with a list of search results matching the selections made. Wipe 15:57, 24 May 2005 (UTC)
A common english word such as organization is surely going to appear more than once in any large general directory or catalogue. Moreover, facet doesn't mean a single concept under which documents (or subclasses) can be classified. It's a general aspect or attribute that can be applied to all entities in some group. The possible values of these attributes are specified so that we have a real documentation language and not just a collection of arbitrary keywords. For example, had we a list of organizations we might select purpose as one of the facets. One allowed value would be education. It's not useful to claim that anything that has keywords or subject headings is faceted (as if the concept of keyword would be a single all-encompassing facet). The Yahoo! directory classification is much like any normal enumerated library classification, isn't it? All it lacks is the shorthand representation in numbers.
You make good points on developing the article. I may try to improve it although I'm not an expert. I agree that reverting additions made in good faith is not nice. Luckily, discussing controvensial edits and issues on article talk pages is always possible and in fact an essential part of the development of the encyclopedia. The removed stuff can also be retrieved from page history.
As for this CC article, it shouldn't really contain much information on facet analysis and faceted classifications in general, or their relationship with other schemes (except for CC). It should concentrate on the special features of CC and leave the other stuff for the article Faceted classification. Wipe 23:06, 24 May 2005 (UTC)
This article provides sources at the bottom, but citations are not used anywhere.
Also, from: Universal Decimal Classification
"... at the end of the 19th century ... the UDC was developed as a new analytico-synthetic classification system..."
This really contradicts the first two sentences in this article:
"Colon classification (CC) ... was the first ever faceted (or analytico-synthetic) classification. The first edition was published in 1933."
