why don't you use the multiple relation option (started with enhanced object relation, not sure about the name of the attribute, but you can create several with a list of related object to check from)
Could you please provide any more details? I don't exactly see what you're proposing.
Naturally, object relations are very handy in various situations. But the key advantage of keywords attribute that I see is that it is lightweight, stored in a model that is very easy to perform operations on (fetching, conditioning). It is also very easy to manage actually: when it comes to few simple tag words, any interface other than coma separated text would be bothering in my opinion.
Anyways, I'd be grateful for any more details. Thanks.
You have the same fetching tools on related objects as you have on keywords, isn't it ?
As for the input form (comma separated), my users are "creative' enough so I can be sure that any of them won't choose the same keyword but a slightly different one (typo included)
I've had better success with a check box list, but YMMV.
<i>You have the same fetching tools on related objects as you have on keywords, isn't it ?</i> When it comes to core eZ API - yes. But if you want to operate on data directly (even if just for reads) than keywords seem much more efficient. However, I haven't studied the object relations' database architecture yet, it might be that I'm wrong. I'll try to confirm that soon.
<i>As for the input form (comma separated), my users are "creative' enough so I can be sure that any of them won't choose the same keyword but a slightly different one (typo included)</i> I believe this is another important issue that you touched, but not necessarily directly related one. If you want to force quality check, than object relations would be a much better choice, but then it would be a closed system (unless I don't see something). On the other hand, as you say - keywords are very risky to be given away to public because of problem you described. But they do great when it comes to a system with content quality enforced outside of eZ Publish.
And I believe they could do much better with additional key ;)
