WhyUsingCategories

Overview

Adding a string "CategorySomething" to one of your pages is in first place nothing but a simple keyword. But there is some magic in place: That keyword is, according to the "WikiSyntax" linked automatically to a page of that name. If you follow the link, this page, if it's already existing, will create then a list of all pages containing that keyword. And because it is created dynamically when called, it is definitly *up-to-date*.

If category names are chosen carefully, the concept is even more powerful. Imagine that you have several categories used to distinguesh between general articles and articles specific to a particular dialect of APL. An article about a special feature of Dyalog APL "Object Orientation" therefore should get the "CategoryArticleDyalogObjectOrientation" category.

If you search for...

• "CategoryArticle" you get list of all articles

• "CategoryArticleDyalog" you get a list of all articles related to Dyalog

• "CategoryArticleDyalogObj" you get a list of all articles relateted to Dyalog starting with "Obj"

All of these lists are created automatically and dynamically and are therefore up-to-date.

Inventing a new category page is simple: choose the appropriate template - the name is obvious. That's it!

You can add several categories to a particular page. For example, you can add both "CategoryDyalogDotNet" and "CategoryGeneralUtils".

When you think about a new category, check the list of already defined categories carefully.
