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 definitely *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 "CategoryArticlesDyalogObjectOrientation" category.
If you search for...
"CategoryArticles" you get list of all articles
"CategoryArticlesDyalog" you get a list of all articles related to Dyalog
"CategoryArticlesDyalogObj" you get a list of all articles relateted to Dyalog starting with "Obj"
Remember, all of these lists are created automatically and dynamically and are therefore up-to-date. In case the page(s) are renamed moved elsewhere, nothing else then the page itself needs to changed.
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" to a particular page.
When you think about a new category, of course it is a good idea to check the list of already defined categories carefully.
