Drupal musings 15: modules and Drupalcon videos

Since picking up the health career model and publishing the model online in 1986 the term holistic bandwidth has emerged. The blog in 2006 and to date has seen other loosely defined terms:

care architecture
4-fold care
cogneography
holistic competency

Using Drupal 6 I've got to a position were I am getting to know core plus some contributed modules. One of the latter is webforms. It's bound to be help seeing what webforms can do in terms of one-way data submission, compared to using CCK - the content construction kit. In webforms the grid component holds great promise, but in creating a grid for music genres I notice there is no validation (which would be quite a trick!). Users should only be able to select one type of music they want to hear most of the time. The validation question is going to help force the issue of getting under the hood. All that reading revealed in previous posts is also needed to sort the theme too.

I remember first coming across the word instantiate. As I write, think about a h2cm glossary and experiment for real with Drupal 6 - I wonder whether the content types I create (in Drupal 7 especially) may help define some of the above and other terms?
