[rules-users] Template Key in DSL

[FrankVhh]

Hi,

Sorry to have kept you waiting.

If you use plain DRL, you have 1 source of information. If you use DSL, you
add an extra source of information by inserting the data in it. Adding DSL
on top of that, adds a third source of information in the form of a
vocabulary.

In theory, the more disperse your information, the more difficult it will be
to maintain. 

Until now, I debugged all templates in the same way. Expand them all
completely and have them outputted to a real DRL file. Than, debug the
outputted file and make corrections in your template accordingly. Here,
imho, there is not much difference in a DSLR template and a DRL template,
provided that you have a stable DSL. This is not a debugging method that I
particullary like, but it gets the job done.

If you assess the difference between a DSLR and a DRL template, the only
differentiator is the DSL. In that case it comes down to the question
whether you have a stable DSL or not. If your DSL is mature, I would prefer
DSLR over DRL for reasons of understandability to non-technical users.
Unless your template is meant to be hidden from the user.

Regards,
Frank
