Hi torgos,
I tried to figure out taxonomies (aka categories/vocabularies?) and how they relate to the Catalog and Manufacturer modules. The thing I'm getting hung up on now is how to relate Manufacturers to the Catalog. What I'd really like to do is create a hierarchy like Manufacturers -> Machines -> Components where manufacturers and machines would be listed under the appropriate level and Products would be listed under Components in the Catalog. Do I need to create a Manufacturer term in Catalog or can I tie in the Manufacturer vocabulary somehow? I'm really curious how some other folks came up with a workable hierarchy similar to what I'm trying to do.
