Small discovery of the day: Algorithmic markup in one plugin interprets the meaning of the remainder of the page which should be designed with this cooperation in mind.
Case in point: Each urban pattern has both a title and an image. I've separated these into an image cluster and a bullet list.
A summary page for related patterns from Michael Mehaffy's Pattern Language for Growing Regions.
This is a mistake. I should place titles under each picture emphasizing the tight relationship. Then I should revise the algorithmic markup of the diagram to read its starting points from the captions rather than the bullet lists as done now. This change will serve to "schematize" the summary pages that will thus feel an organizing pressure from the wiki itself.
