Via Seth Gottlieb I have found this really good presentation on content modelling for content management systems by Deane Barker:

Cleve Gibbon's recent well-written series on content modelling is closely related to Deane's presentation. Make sure to have a look if you are interested in that area.

I really like Deane's presentation, at least when I look at it from the paradigm that proper content management needs a-priori content modelling. Lately, I have come to question this idea, but that shall be the topic of a different post.
