I think BJ is right here. It sounds like you have a specific set of requirements (even if they aren't totally defined or clear yet), and in order to implement a system some analysis and design will be required, and that isn't something you can get from a book or an open source project.

Both are simply resources that once understood can be used as a foundation and tools to make your design and implementation efforts easier and less risky.

first would be a document that details your whole opertaion.
then, against that document, deciding how to implement that into ofbiz. it is best to get someone that understand ofbiz to go over the document
with you to accomplish this in a short time.

Sunder,

Thanks for your reply. If I can find a copy of this book I'll check out that chapter. In the meantime, does is it seem odd to anyone else that such a core functionality of an Apache project is documented only in a $55 book? Having been published in 2001, this is not sitting on the shelves at Barnes
and Noble or Borders any more (at least, not where I live).

Perhaps I need to modify my original question - can anyone explain to me how to decide what elements of a product should be features, configurations, and
subassemblies and the tradeoffs between them?

In my opinion, You may be better off referencing the book and ofbiz data
(entity) schema in parallel since you are sure about your needs.

Your questions would be answered differently for each industry.

BJ,

Thanks for your response. I don't mean to come off sounding cheap, as I
will
definitely consider buying this book if I can figure out how to make OFBiz do what I need, but surely there is a free (as in beer) resource? I'm
still
in the proof of concept phase with my OFBiz adoption...

The wiki page doesn't really answer the "why" questions I posed. I think they're a great resource to understand how to build and edit my catalog
once
I've designed how the products will relate to one another, but I'm without
a
guideline for which tactic to adopt.

If it helps, the target industry is hand built custom musical instruments. There are dozens of options for every part of the instrument itself, and
more options for the accessories, like the case and bow.

Some of the composition questions answer themselves. Obviously the
components that are going to be available for sale as separate components, like the case and bow, will themselves be products. And since there are so many dimensions of options, it seems inefficient, even if it is possible,
to
make every permutation into it's own variant product with standard
features.
Does this mean it should be purely configuration, with nothing represented as a feature? Or, if there should be a mix, as I suspect, how should I go
about deciding what should be a configuration and what should be a
feature?
Also, there's a hole in the knowledge I've sponged up so far as to what
subassemblies are good for and when I should use those.

In the end, the goal is to a traditional eCommerce site that makes it possible to order non-custom products and to request quotes for custom instruments. We'd like to leverage as much of the MRP functionality as
possible, even though right now the entire production facility is
literally
in a basement.
