CookBook - Data Models

A "category" data model - for use in custom documents, weblog entries, etc.

An efficient parent/child relationship - Similar to the "category" data model above, but doesn't use recursive functions, neither multiple queries.

Using markup filters in models - efficiently using Markdown, Textile, etc. in models

A "Constants" class - a neat trick to enhance the choices functionality

Splitting models to multiple files - it is possible after all

Predicates - or "3-tuples" or "semantically enriched many-to-many relationships".

Generic Attributes - named attributes, slightly more refined than tags.
