Trails: passages into Pattern-based design and analysis
Paradoxically, often as more expert knowledge is embedded in a pattern language it becomes less accessible to novices. The Learning Patterns project has tried to address this issue by a small set of Trails which accompany our pattern language.
A trail is an informal illustrative account of how patterns were derived or how they might be used. It is not presented as hard data or detailed analysis, but rather as an aid for the casual reader.
