Title: Builder category and @Keywords
Post by: pajaro on May 18, 2014, 08:27:46 PM
I thought I understood the difference between regular (IMatch) categories and @Keywords. But now, playing with @Builder I found that a category created from the @Builder results could be stored as an IMatch category, but not as a @Keyword. I am confused - why this is not possible? As I use exclusively @Keywords having this option would be very useful...

Thanks,

Pavel.

If you persist the temporary results of the @Builder into a category, this category becomes a formula-based category. It dynamically calculates it's contents ("files") by evaluating the formula.

Formula-based categories cannot be used as child categories for data-driven categories, including the special @Keywords category.

I see. So, theoretically, if it is converted to @Keywords category, it can no longer be updated if new files are added to the database.

No.

The @Keywords category is a data-driven category. This means it's child categories are automatically added or removed by scanning the actual keywords in the database. Like all other data-driven categories.

@Keywords has some special features, for example, you are allowed to create new child categories (aka 'keywords') manually. But that cannot work with categories which do not contain files but have formulas instead. These two concepts cannot be combined - and what would be the result?

You cannot add keywords to categories that use formulas to be generated - makes sense. I think I got it  :)
