Help with concept

[JonasE]

Hello all,

A client has requested something that to me sounds like a simplistic expert system. He wants me to develop a system that can take certain properties that the user enters and based on those selections recommend a product.
I have given this some thought, and I figure that using some kind of tagging system might be appropriate? I.E. I would assign certain properties to certain products, and based on the users selections (through checkboxes probably), products matching those selections would show up.
Does anyone have any experience building something similar? Any examples? Am I on the right track?

Thanks a lot.

Jonas
