Part 4: Concept Lattice
Seems closely related to the notion of a Concept, as defined by class threads in tapestry theory: a concept is the set of all nodes and edges traversed by the set of all class threads that emanate from a single node. So if the node is Widget, then an example of a class thread emanating from that node would be:. A second class thread might exist that starts and ends at the same nodes but traverses different subsets, eg: widget—>widgets—>round widgets—>my widget
So class threads create a DAG that organizes things into sets and subsets. Which I think a lattice does too, right?
The most important aspect of class threads is that the class header node (widget) and the superset node (widgets) must be distinct. The temptation is to merge them together into one node for the sake of simplicity, but that would be a mistake; you have to keep them separate if you want to integrate concepts the way that tapestry theory allows you to do. Seems like a mundane detail, but it’s important.
