A pattern starts with its seed environments. These may as well be other patterns themselves. They acknowledge for the originating context of a given case.
In case of formulating a pattern language, the convention is to combine a selected set of patterns into an inventory, which is in turn being used to model linear dependency paths with strong support by visual top-down and left-right hierarchies. These may as well be layed out by graphing their topological relations into a projected space. This emphasized notion of a direct acyclic graph's flow of meaning aids the reader's narrative comprehension.
Recombinatory utilisation and freely traversing value can only then be found, if the sustaining processus, which eventually led to affirmed conclusions, retains discoursive integrity and epistemic clarity.
